背景
在本教程中,我们将以 LiCl 熔体为例,详细介绍深度势能(Deep Potential)模型的训练和应用。深度势能模型是一种基于机器学习的方法,用于精确描述原子间相互作用的势能面。通过训练这种模型,我们可以高效地模拟材料的结构、动力学和热力学性质。具体包括以下示例:
- 章节 1: LAMMPS 经典分子动力学模拟
- 章节 2: ABACUS 第一性原理计算
- 章节 3: DeePMD-kit 深度势能模型训练
- 章节 4: DP-GEN 构建训练数据并生成深度势模型
- 章节 5: LAMMPS 深度势能分子动力学研究
总的来说,通过结合经典分子动力学模拟(如 LAMMPS)、第一性原理计算(如 ABACUS)和深度势能模型构建(DeePMD-kit 和 DP-GEN),我们可以多角度地研究 LiCl 熔体的性质。这些方法和工具的组合为研究复杂材料系统提供了强大的支持,帮助我们更好地理解材料在不同条件下的性能。

1.5 LAMMPS 分子动力学模拟结果与分析
运行完成后,我们可以看到在当前文件夹下生成了以下几个文件:
- log.lammps:日志文件,记录了模拟过程中的各种输出信息,包括初始系统状态、MD过程中的能量、温度、压力等物理量,以及各种计算的结果。
- licl.dump:轨迹文件,记录了模拟系统在每个时间步长中所有原子的位置、速度等信息。
- licl.rdf:径向分布函数(RDF)文件,记录了每 Nfrequency 步数输出的 RDF。
- licl.msd:均方位移(MSD)文件,记录了模拟系统中离子的均方位移随时间的变化。
对于 licl.dump 文件,我们可以使用 OVITO 等软件对完整轨迹进行可视化。在这里,我们使用 ASE 仅查看最后一帧的图像。了解 ASE 的使用,可以阅读《快速开始 ASE》
Atoms(symbols='Cl54Li54', pbc=True, cell=[13.4422702789, 13.4422702789, 13.4422702789])
了解一下什么是径向分布函数?为什么分子动力学中要计算径向分布函数?
径向分布函数(Radial Distribution Function,RDF)是一种描述在固体、液体和气体等多原子系统中,原子或分子间相对位置和距离分布的统计量。它可以用来表示从一个选定的原子或分子出发,与其距离为 r 的其他原子或分子的概率密度。径向分布函数 g(r) 可以表示为:
其中,N 是距离 r 范围内的原子或分子数,V 是体积,ρ 是原子或分子的平均密度, 是在距离 r 附近的原子或分子数增加率。
我们以氧气为例。在氧气中,氧分子之间主要通过范德华力相互作用。我们可以计算氧分子间的径向分布函数来分析这种相互作用。
考虑氧气中的一个氧分子,以其为中心,计算距离 r 内其他氧分子的概率密度。径向分布函数 g(r) 描述了在距离 r 处找到另一个氧分子的概率密度,相对于在完全随机分布的情况下找到另一个氧分子的概率密度。
在氧气中计算氧分子之间的径向分布函数 g(r),我们可以观察到:
当 r 很小时,g(r) 接近 0,这意味着氧分子不可能位于非常接近的位置,这是由于它们之间的排斥力。
随着 r 的增加,g(r) 的值会出现一个峰值,这个峰值对应于氧分子间最可能的距离,即范德华力最强的距离。
当 r 继续增加时,g(r) 将逐渐趋于 1,这意味着在较大的距离范围内,氧分子的分布接近随机分布。
当 r 增加时,g(r) 趋近于1的原因是,g(r) 是相对于完全随机分布的概率密度。在距离很远时,原子或分子之间的相互作用变得微弱,分子分布趋近于随机。
当我们提到 g(r) 趋近于1时,我们是在描述这样一个现象:在较大的距离范围内,分子之间的相互作用变得不那么重要,因此它们的分布接近于随机分布。在这种情况下,实际系统中找到一个分子的概率与随机分布中找到一个分子的概率相近,因此 g(r) 接近1。
需要注意的是,g(r) 本身并不是概率,而是概率密度。在径向分布函数 g(r) 的情况下,它表示的是在距离 r 附近找到另一个分子的相对可能性,因此是一个概率密度函数。g(r) 的值并不直接反映在某个距离 r 处找到分子的概率,而是相对于随机分布的概率密度。因此,当 r 增加时,g(r) 不会无限增大,而是趋于一个稳定值,即 1。这表明分子分布在远离中心分子的区域趋近于随机。
从这个简单的例子中,我们可以看到径向分布函数是如何帮助我们了解氧分子间相互作用和分布的。同样的方法也可以应用于其他气体系统,以揭示其原子或分子间的相互作用和结构性质。
在分子动力学(Molecular Dynamics,MD)模拟中,径向分布函数是一种重要的工具,因为它可以提供关于系统的结构信息,帮助我们了解原子或分子间的相互作用和系统的组织方式。计算径向分布函数可以帮助我们:
- 描述和量化原子或分子之间的距离分布,进而分析分子之间的相互作用和有序性;
- 分析系统的相变过程,例如液体 - 固体相变、液体 - 气体相变等;
- 了解系统的局部结构,例如液体中的簇形成、气体中的原子或分子分布规律等;
- 与实验数据(如 X 射线衍射、中子散射等)进行对比,验证模拟结果的准确性。
因此,在分子动力学模拟中计算径向分布函数对于分析和解释模拟结果具有重要意义。
对于 licl.rdf 文件,我们可以利用如下 Python 脚本进行进一步处理和绘图:
对于 licl.msd 文件,我们可以利用如下 Python 脚本进行进一步处理计算得到扩散系数 D 和绘图:
我们如何通过均方位移(MSD)来计算扩散系数呢?
我们可以通过均方位移(MSD)计算扩散系数,因为它们之间存在直接的数学关系。扩散系数是一个衡量粒子在物质中传播的速度的物理量,它与粒子的均方位移(MSD)相关。
在扩散过程中,粒子的运动符合随机游走或布朗运动模型。对于三维随机游走,粒子在每个方向上的位移是独立的,我们可以将总的均方位移表示为三个方向的位移平方和的平均值:
根据爱因斯坦关系(Einstein Relation)和菲克定律(Fick's Law),我们可以得到扩散系数(D)和均方位移之间的关系:
在这个公式中, 是时间, 是扩散系数。公式表明,MSD 随时间线性增长,其斜率与扩散系数成正比。因此,我们可以通过对 MSD 数据进行线性拟合,计算出 MSD 与时间的线性关系,从而获得扩散系数。
需要注意的是,这种方法基于扩散过程中粒子的运动是随机的、无记忆的假设。在某些情况下,这种假设可能不成立,比如在有长程相互作用或有序晶格中的粒子运动。在这种情况下,我们需要采用其他方法来计算扩散系数。然而,在许多实际应用中,尤其是液体和气体中的粒子扩散,使用 MSD 计算扩散系数是一种非常有效的方法。
Diffusion Coefficients of Li+: 7.543639618987788e-09 m^2/s Diffusion Coefficients of Cl-: 3.5602726197335397e-09 m^2/s
以及从均方位移导出的扩散系数的数值:
Diffusion Coefficients of Li+: 7.543639618987788e-09 m^2/s
Diffusion Coefficients of Cl-: 3.5602726197335397e-09 m^2/s
注意:扩散系数的值可能和文献报道存在差异。我们可以考虑以下几个方面,以获得更准确的值:
- 首先在 NPT 系综进行模拟,将压力固定在 0 GPa,获得平衡体积。然后在平衡体积下进行 NVT 模拟。
- 使用更大的模拟盒子。
- 设置更长的模拟时间。
章节 2:ABACUS 第一性原理计算
对于 LiCl 熔体,我们还可以使用 ABACUS (Atomic-orbital Based Ab-initio Computation at UStc) 软件进行第一性原理计算。ABACUS 是一个基于密度泛函理论(DFT)的材料模拟软件,可以准确地计算原子间相互作用。通过使用 ABACUS,我们可以从电子结构层面研究 LiCl 熔体的性质。
本章节目标
在学习本章节后,你能够:
- 熟悉 ABACUS 软件的输入和输出文件;
- 为 LiCl 熔体编写 ABACUS SCF 计算输入文件并进行计算;
- 为 LiCl 熔体编写 ABACUS MD 计算输入文件并进行计算;
2.1 下载教程资源
在本章节中,我们以 LiCl 熔体分子为例,进行 ABACUS 第一性原理计算。我们已经在 LiCl_DP_Tutorial_Example/chapter2 中准备了需要的文件,本教程采用 ABACUS v3.1.0 完成。
在 LiCl_DP_Tutorial_Example/chapter2 文件夹中存在如下 5 种文件:
INPUT

2.2 ABACUS 自洽计算
首先,我们将使用 ABACUS 软件为 LiCl 熔体执行自洽计算。
自洽,是自洽场计算(SCF, self-consistent field calculation)的简称,它是密度泛函理论(DFT)算法的基础,也是 DFT 被称为第一性原理方法的原因。
从自洽场计算中我们可以得到一个体系的基态结构和基态能量。
基态结构使得我们可以得到体系的结构参数,例如晶胞参数,化学键键长键角等,而基态能量使得我们可以进一步得到原子受力和晶体材料的应力-应变性质等。
因此自洽场计算是开始做 DFT 计算的基础。

可以看到,经过 11 次迭代后,电荷密度收敛,密度误差达到 7.23978511026e-08,最终总能量为 -19448.1248715 eV。
在这个练习中,我们熟悉了 ABACUS 软件的输入文件,学会了如何为 LiCl 熔体编写 ABACUS SCF计算输入文件,执行计算并查看计算收敛情况。
2.3 ABACUS 量子分子动力学计算
量子分子动力学(Quantum Molecular Dynamics,QMD):将量子力学的原理应用于分子动力学中,考虑电子的波动性和粒子性。
除了 1.4 与 2.3 中提到的两种分子动力学外,还有如:
蒙特卡罗分子动力学(Monte Carlo Molecular Dynamics,MCMD):使用随机模拟的方法来模拟分子的运动,通过统计模拟得到分子系统的状态。
多尺度分子动力学(Multiscale Molecular Dynamics,MMD):将不同尺度的分子动力学方法结合起来,以提高模拟效率和准确性。
拉格朗日分子动力学(Lagrangian Molecular Dynamics,LMD):采用拉格朗日力学的方法来描述分子系统的运动。
基于机器学习的分子动力学(Machine Learning Molecular Dynamics,MLMD):利用机器学习方法来辅助分子动力学模拟,以提高模拟效率和准确性。
在这篇教程中即将学习的 DeePMD-kit 即为基于机器学习的分子动力学。
2.3.1 ABACUS MD 计算输入文件
ABACUS MD 计算所需的输入文件与上述 ABACUS SCF 计算的输入文件相似。
我们仅需要修改 INPUT 文件,而其他文件无需更改。修改后的 INPUT 文件示例如下:
INPUT_PARAMETERS
#Parameters (1.General)
ntype 2
symmetry 0
vdw_method d3_bj
#Parameters (2.Iteration)
ecutwfc 100
scf_thr 1.0e-7
scf_nmax 120
#Parameters (3.Basis)
basis_type lcao
#Parameters (4.Smearing)
smearing_method gauss
smearing_sigma 0.002
#Parameters (5.Mixing)
mixing_type pulay
mixing_beta 0.4
#Parameters (6.md)
calculation md # calculation:计算类型,这里选择分子动力学(md)
cal_force 1
cal_stress 1
md_nstep 500 # md_nstep:分子动力学模拟的总步数,设为 500
md_type 1 # md_type:模拟类型,这里选择 NVT 系综
md_dt 1 # md_dt:时间步长,设为 1
md_tfirst 900 # md_tfirst:目标温度,设为 900 K
md_restart 0 # md_restart:是否为续算,设为 0 表示不是续算
md_dumpfreq 1 # md_dumpfreq:输出分子动力学信息的频率,设为 1 表示每一步都输出
out_stru 1 # out_stru:输出结构信息的选项,设为 1 表示输出
INPUT 文件定义了 LiCl 熔体的分子动力学(MD)模拟。与之前的 LAMMPS MD 一致,模拟在 NVT 系综下进行,时间步长 ,温度为 900 K。
在 LiCl_DP_Tutorial_Example/chapter2/abacus_md/ 文件夹中我们为你准备好了本次计算所需的输入文件。
考虑到 DFT 计算成本相对较高,这里模拟时间为 ()。
注意:使用 LCAO 基组计算时,通常需测试能量、力、应力对不同轨道半径截断值和不同 k 点(k_spacing)设置的收敛性。出于简化教程的目的,这里我们没有做这样的测试。
2.3.2 运行 ABACUS MD 计算
准备好以上所有输入文件后,我们可以执行 LiCl 熔体的MD计算。例如,使用命令行:
注意: 由于我们需要的 ABACUS 版本为 ABACUS 3.1,这一步需将镜像更换为abacus:3.1.4-toolkit-notebook

可以看到,即使计算步数仅为 LAMMPS 经典分子动力学计算的 ,
ABACUS 量子分子动力学计算所需要的时间也是 LAMMPS 经典分子动力学计算的 倍!
成本比高达约 63732 倍!

该文件记录了分子动力学模拟的信息。包括:
- MD的步数(MDSTEP)
- 晶格常数(LATTICE_CONSTANT)和晶格矢量(LATTICE_VECTORS)。
- 应力张量(VIRIAL),单位 KBAR。
- 每个原子的索引、标签、坐标位置(POSITIONS)和受到的力(FORCE),力的单位 eV/Angstrom。
这里提供了一个 Python 脚本,可以提取原子坐标,计算 RDF 并将 RDF 数据保存到名为 gr_Li-Cl、gr_Li-Li 和 gr_Cl-Cl 文件。
从 ABACUS MD计算的 RDF 如图。我们可以观察 ABACUS 和 LAMMPS MD 获得的 900K 下的 LiCl 熔体的 RDF 是否存在差异。注意,由于模拟体系较小和模拟时间较短,ABACUS MD 计算的 RDF 曲线并不光滑,更大的模拟体系或者更长的模拟时间将有助于改善这一情况。
在这个练习中,我们学习了如何为 LiCl 熔体编写 ABACUS MD 计算输入文件,执行计算,和 MD 轨迹处理。
章节 3:DeePMD-kit 深度势能 (DP) 模型训练
对于 LiCl 熔体,我们可以使用 DeePMD-kit 软件包,为其训练一个深度势能模型。DeePMD-kit 是一个基于深度学习的分子动力学模拟工具,可以根据第一性原理数据训练高精度的 DP 模型。在这个示例中,我们可以利用 ABACUS 第一性原理数据和 DeePMD-kit 训练一个 LiCl 熔体的 深度势能 (DP) 模型。
DeePMD-kit 的详细原理是:通过建立深度学习模型来学习高成本第一性原理计算获得的数据,得到的深度势能模型,并将该模型应用于后续的分子动力学模型中,用于控制分子间势,这即是「深度势能分子动力学」名称的由来。
DeePMD-kit 深度势能分子动力学方法大大节省了量子分子动力学所需的计算成本,将分子动力学模拟的规模从以往的几千原子提升至上亿原子的级别,同时也保留了显著优于经典分子动力学的模拟精度。相关成果曾获2020年度⾼性能计算领域最⾼奖 ACM 戈登贝尔奖。
本章节目标
学习完本章节后,你将能够:
- 掌握 DeePMD-kit 输入文件编写
- 能够进行数据准备、训练/冻结/压缩/测试和分子动力学任务
下载教程资源
在本章节中,我们以 LiCl 熔体分子为例,训练深度势能模型。我们已经在 ./LiCl_DP_Tutorial_Example/chapter3 中准备了需要的文件。
在 ./LiCl_DP_Tutorial_Example/chapter3 文件夹下有 00.data,01.train 和 02.lmp 共 3 个子文件夹。
- 00.data 文件夹用于存放训练和测试数据,
- 01.train 包含使用 DeePMD-kit 训练模型的示例脚本,
- 02.lmp 包含用于分子动力学模拟的 LAMMPS 示例脚本。
本教程采用 DeePMD-kit(2.2.1)程序完成。
3.1 准备训练数据
在 2.3 中已经执行了ABACUS MD 计算。你可以使用如下 Python 脚本,其中调用 dpdata 的工具,将 ABACUS MD 生成的数据(数据格式abacus/md)转换为 DeePMD-kit 训练所需的数据格式(NumPy数组)。
# 数据包含 501 frames # 训练数据包含 401 frames # 验证数据包含 100 frames
我们可以看到 abacus_md 文件包含 501 帧数据。 我们随机选取 100 帧作为验证数据,其余的401帧作为训练数据。在开始训练之前,我们可以先检查 training_data 或 validation_data 文件夹。
box.raw energy.raw set.000 type_map.raw coord.raw force.raw type.raw virial.raw
这些文件的作用如下:
set.000
:是一个目录,包含压缩格式的数据(NumPy压缩数组)。所有训练数据应首先转换为此格式,然后在 DeePMD-kit 中使用。该数据格式在 DeePMD-kit 手册中有详细解释,可以在 DeePMD-kit Data Introduction 中找到。type.raw
:是一个文件,包含原子的类型(以整数表示)。type_map.raw
:是一个文件,包含原子的类型名称。
让我们来看一下这些文件:
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
这告诉我们这个例子中有 108 个原子,其中 54 个原子由类型"0"表示,54 个原子由类型"1"表示。有时需要将整数类型映射到原子名称。映射可以通过文件type_map.raw
给出。
由于系统中的所有帧都具有相同的原子类型和原子序号,因此我们只需为整个系统指定一次类型信息。
Li Cl
其中原子 Li 被赋予类型 0,原子 Cl 被赋予类型 1。
3.2 准备输入脚本
训练数据准备完成后,接下来就可以进行训练。让我们进入训练目录看一下运行所需的脚本:
{ "_comment": " model parameters", "model": { "type_map": ["Li", "Cl"], "descriptor" :{ "type": "se_e2_a", "sel": [128, 128], "rcut_smth": 0.50, "rcut": 7.00, "neuron": [20, 40, 80], "resnet_dt": false, "axis_neuron": 4, "seed": 1, "_comment": " that's all" }, "fitting_net" : { "neuron": [200, 200, 200], "resnet_dt": true, "seed": 1, "_comment": " that's all" }, "_comment": " that's all" }, "learning_rate" :{ "type": "exp", "decay_steps": 5000, "start_lr": 0.001, "stop_lr": 3.51e-8, "_comment": "that's all" }, "loss" :{ "type": "ener", "start_pref_e": 0.02, "limit_pref_e": 1, "start_pref_f": 1000, "limit_pref_f": 1, "start_pref_v": 0, "limit_pref_v": 0, "_comment": " that's all" }, "training" : { "training_data": { "systems": ["../00.data/training_data"], "batch_size": "auto", "_comment": "that's all" }, "validation_data":{ "systems": ["../00.data/validation_data"], "batch_size": "auto", "numb_btch": 1, "_comment": "that's all" }, "numb_steps": 400000, "seed": 10, "disp_file": "lcurve.out", "disp_freq": 1000, "save_freq": 10000, "_comment": "that's all" }, "_comment": "that's all" }
input.json 包含了 DP 模型训练过程中所需的各种参数,定义和控制训练任务。这些参数在 DeePMD-kit 手册中有详细的解释,所以这里只做简单介绍。
在 model 模块, 指定嵌入和拟合网络的参数。
"model":{
"type_map": ["Li", "Cl"], # 元素名称
"descriptor":{
"type": "se_e2_a", # 描述符类型
"rcut": 7.00, # 截止半径
"rcut_smth": 0.50, # 光滑截止半径
"sel": [128, 128], # 原子的选定邻居数
"neuron": [20, 40, 80], # 嵌入网络尺寸
"resnet_dt": false,
"axis_neuron": 12, # 嵌入子网络横向尺寸
"seed": 1,
"_comment": "that's all"
},
"fitting_net":{
"neuron": [200, 200, 200], # 拟合网络尺寸
"resnet_dt": true,
"seed": 1,
"_comment": "that's all"
},
"_comment": "that's all"'
},
描述符 se_e2_a
用于 DP 模型的训练。将嵌入和拟合神经网络的大小分别设置为 [20, 40, 80] 和 [200, 200, 200]。 里的成分会从 0.5 到 7 Å 平滑地趋于 0。
下面的参数指定学习效率和损失函数:
"learning_rate" :{
"type": "exp",
"decay_steps": 5000, # 学习率下降间隔
"start_lr": 0.001, # 起始学习率
"stop_lr": 3.51e-8, # 结束学习率
"_comment": "that's all"
},
"loss" :{
"type": "ener",
"start_pref_e": 0.02, # 能量起始权重
"limit_pref_e": 1, # 能量最终权重
"start_pref_f": 1000, # 力起始权重
"limit_pref_f": 1, # 力最终权重
"start_pref_v": 0, # 维里
"limit_pref_v": 0,
"_comment": "that's all"
},
在损失函数中, 从 0.02 逐渐增加到 1 ,而 f 从 1000 逐渐减小到 1 ,这意味着力项在开始时占主导地位,而能量项和维里项在结束时变得重要。这种策略非常有效,并且减少了总训练时间。 设为 0 ,这表明训练过程中不包含任何维里数据。将起始学习率、停止学习率和衰减步长分别设置为 0.001,3.51e-8,和 5000。模型训练步数为 。
训练参数如下:
"training" : {
"training_data": {
"systems": ["../00.data/training_data"], # 训练数据路径
"batch_size": "auto", # 自动确定,natoms*batch_size≥32
"_comment": "that's all"
},
"validation_data":{
"systems": ["../00.data/validation_data/"],
"batch_size": "auto",
"numb_btch": 1, # 测试帧数
"_comment": "that's all"
},
"numb_steps": 400000, # 训练步数
"seed": 10,
"disp_file": "lcurve.out", # 写入学习曲线到文件
"disp_freq": 1000, # 写入学习曲线的频率
"save_freq": 10000, # 保存模型相关文件频率
},
3.3 模型训练
准备好训练脚本后,我们可以用 DeePMD-kit 开始训练,只需运行:

第 4、5 和 6、7 列分别介绍了能量和力的训练和测试误差。 经过 4000,00 步训练,能量测试误差小于 1 meV,力测试误差小于 20 meV/Å。可以通过简单的 Python 脚本对该文件进行可视化:
当训练过程异常停止时,我们可以从提供的检查点重新开始训练,只需运行
需要注意的是 input.json 需要和上一个保持一致。
3.4 冻结和压缩模型
在训练结束时,保存在 TensorFlow 的 checkpoint 文件中的模型参数通常需要冻结为一个以扩展名 .pb 结尾的模型文件。 只需执行:

3.6 使用 LAMMPS 运行深度势能分子动力学
首先,我们将 01.train 目录中的 DP 模型复制到 02.lmp 目录
让我们查看一下 02.lmp 目录下的文件:
64_dpmd_rdf.png licl-compress.pb licl.dump licl.rdf ave_rdf.txt licl.data licl.in log.lammps
其中 licl.data 给出了 LiCl 熔体 MD 模拟的初始配置,文件 licl.in 是 lammps 输入脚本。 可以检查 licl.in 并发现它是一个用于 MD 模拟的相当标准的 LAMMPS 输入文件,与章节 1 中的 licl.in 文件相比,在原子类型和势函数参数设置上略有不同:
atom_style atomic
和
pair_style licl-compress.pb
pair_coeff * *
其中调用 pair style deepmd 并提供模型文件 licl-compress.pb,这意味着原子间相互作用将由名为 licl-compress.pb 的 DP 模型计算。可以以标准方式执行:
稍等片刻,MD 模拟结束,生成 log.lammps 和 licl.dump 文件。 它们分别存储热力学信息和分子的轨迹,我们可以使用 chapter1 中提供的 Python 脚本计算 RDF。
让我们来对比一下由经典分子动力学、量子分子动力学、深度势能分子动力学计算得到的 rdf 曲线:
可以发现,相对于 LAMMPS 经典分子动力学计算得到的结果,由 DeePMD-kit 深度势能分子动力学计算得到的结果更接近 ABACUS 量子分子动力学得到的结果,具有更高的准确度。
而在模拟步数为量子分子动力学的 1000000/500 = 200 倍的情况下,时间仅为 19 mins / 9 h 30 mins = 0.03。在保证较高精度的前提下,大大降低了计算成本。
接下来,我们将使用 DP-GEN 工作流进一步优化我们的深度势能分子动力学模拟。在更大空间和时间尺度上研究 LiCl 熔体的结构、动力学和热力学性质。
章节 4:DP-GEN 构建训练数据并生成深度势模型
为了构建高质量的LiCl熔体深度势能模型的训练数据集,我们可以使用 DP-GEN(Deep Potential GENerator) 软件。DP-GEN 是一个自动化的训练数据集生成工具,可以根据预设的参数和条件搜索材料的结构和相态空间。
本教程采用DeePMD-kit(2.2.1),ABACUS(3.2.0)和DP-GEN(0.11.0)程序完成。
本章节目标:
在学习本章节后,你将能够:
- 掌握 DP-GEN 输入文件(param.json 和 machine.json) 中主要关键词的设置;
- 利用 DP-GEN 为 LiCl 熔体构建训练数据并生成深度势模型;
- 分析和解读 DP-GEN 迭代过程中的结果和输出文件,以便更好地理解模型训练的过程和效果。
4.1 下载教程资源
在本教程中,我们以 LiCl 熔体分子为例,构建训练数据并生成深度势模型。我们已经在 LiCl_DP_Tutorial_Example/chapter4 中准备了需要的文件。
/usr/bin/sh: 1: pip: not found /usr/bin/sh: 1: pip: not found
让我们来查看一下 LiCl_DP_Tutorial_Example/chapter4 中所含的文件。
LiCl_DP_Tutorial_Example/chapter4 ├── abacus │ ├── Cl_ONCV_PBE-1.2.upf │ ├── Cl_gga_8au_100Ry_2s2p1d.orb │ ├── Li_ONCV_PBE-1.2.upf │ └── Li_gga_8au_100Ry_4s1p.orb ├── dpgen.log ├── iter.000000 │ └── 00.train ├── machine.json ├── max-devi-f.png ├── max_devi_f.py └── param_abacus.json 3 directories, 9 files
*.upf
和*.orb
是 ABACUS 的输入文件param.json
是运行当前任务的 DP-GEN 设置。machine.json
是一个任务调度程序,其中设置了计算机环境和资源要求。
4.2 DP-GEN 输入文件
DP-GEN 运行过程包含一系列连续迭代,按顺序进行,例如将系统加热到特定温度。每次迭代由三个步骤组成:
- 探索 (Exploration)
- 标记 (Labeling)
- 训练 (Training)。
首先,介绍 DP-GEN 运行过程所需的输入文件。
param.json
param.json
中的关键字可以分为 4 个部分:
- 系统和数据 (System and Data):用于指定原子类型、初始数据等。
- 训练 (Training):主要用于指定训练步骤中的任务;
- 探索 (Exploration):主要用于在探索步骤中指定任务;
- 标记 (Labeling):主要用于指定标记步骤中的任务。
这里我们以 LiCl 熔体为例,介绍 param.json
中的主要关键词。

"model_devi_f_trust_hi" | int | 选择的力上限。如果为 List,则应分别为每个索引设置sys_configs。 |
"model_devi_clean_traj" | bool or int | 如果model_devi_clean_traj的类型是布尔类型,则表示是否清理MD中的traj文件。如果是 Int 类型,则将保留 traj 文件夹的最新 n 次迭代,其他迭代将被删除。 |
"model_devi_clean_traj" | bool | 控制在模型偏差(model_devi)阶段是否合并生成的轨迹文件 |

对于每次迭代,在不同的温度(900, 1000, 1100和1200 K)和压力条件(0, 1e-3, 1e-2, 1e-1和1 GPa)下,使用 NPT 系综和“sys_configs_prefix”和“sys_configs”指定的构型进行 100000 步模拟,时间步长为0.001 ps。
我们选择保存 MD 轨迹文件,并将保存频率“trj_freq”设置为 10。如果轨迹中构型的“max_devi_f”介于 0.08 和 0.18 之间,DP-GEN 会将该结构视为候选结构。
如果要保存 traj 文件夹的最近 n 次迭代,可以将“model_devi_clean_traj”设置为整数。

machine.json
DP-GEN 运行过程中的每次迭代都由三个步骤组成:探索、标注和训练。因此,machine.json 由三个步骤组成:train、model_devi 和 fp。每个步骤都是字典列表。每个字典都可以被视为一个独立的计算环境。
在本节中,我们将向您展示如何在 Bohrium 上执行train
, model_devi
和fp
步骤。 对于每个步骤,需要三种类型的关键词:
- 命令 (Command):提供用于执行每个步骤的命令。
- 机器 (Machine):指定机器环境(本地工作站、本地或远程集群或云服务器)。
- 资源 (Resources):指定组、节点、CPU 和 GPU 的数量;启用虚拟环境。
在此示例中,我们在Bohrium上执行train
步骤。

案例说明:
在 command 参数中,train
,model_devi
和fp
步骤使用的程序分别为 DeePMD-kit,LAMMPS 和 ABACUS,其相应的调用命令分别为
dp
export LAMMPS_PLUGIN_PATH=/opt/deepmd-kit-2.1.5/lib/deepmd_lmp && lmp -i input.lammps -v restart 0
OMP_NUM_THREADS=1 mpirun -np 4 abacus
在 machine 参数中,"scass_type"指定训练使用的机型。
对于
train
和model_devi
步骤,建议使用GPU机型,这里使用的机型为“c12_m92_1 * NVIDIA V100”。对于
fp
步骤,建议使用CPU机型,这里使用的机型为“c8_m64_cpu”。
在 resources 参数中,“group_size”指定了一个 group 中任务的数量。
对于
train
和model_devi
步骤,由于任务数量较少(分别为4和20),我们可以将“group_size”设置为 1, 使所有任务同时执行。 对于fp
步骤,由于任务数量较多(200),我们可以将“group_size”设置为 2, 使100个任务同时执行。
注意:用户需要填入自己的 Bohrium 账户邮箱,密码和项目ID(共三处)。其他参数通常不需修改。
4.3 运行DP-GEN
准备好了 param.json
和 machine.json
,我们就可以通过以下方式轻松运行 DP-GEN:
请输入你的 Bohrium 账户: quehaohui@dp.tech 请输入你的 Bohrium 密码: ········ 请输入你的 Bohrium 项目 ID【请输入整数】: 12788
修改配置文件后,配置文件中携带你的个人账户信息,请注意保密!
通常情况下,该文件不会被分享,你可以运行本文档附录的代码以初始化该配置文件。/usr/bin/sh: 1: cd: can't cd to LiCl_DP_Tutorial_Example/chapter4/
成功运行 DP-GEN 之后,在 LiCl_DP_Tutorial_Example/chapter4 下,可以发现生成了一个文件夹和两个文件:
- iter.000000 文件夹:包含 DP-GEN 迭代过程中第一次迭代的主要结果;
- dpgen.log 文件:主要记录时间和迭代信息;
- record.dpgen 文件:记录迭代过程的当前阶段。
如果 DP-GEN 的进程由于某种原因停止,DP-GEN 将通过 record.dpgen
文件自动恢复主进程。我们也可以根据自己的目的手动更改它,例如删除上次迭代并从一个检查点恢复。
record.dpgen
文件每行包含两个数字:第一个是迭代的索引,第二个是 0 到 9 之间的数字,记录每个迭代中的哪个阶段当前正在运行。
Index of iterations | Stage in each iteration | Process |
---|---|---|
0 | 0 | make_train |
0 | 1 | run_train |
0 | 2 | post_train |
0 | 3 | make_model_devi |
0 | 4 | run_model_devi |
0 | 5 | post_model_devi |
0 | 6 | make_fp |
0 | 7 | run_fp |
0 | 8 | post_fp |
4.4 结果分析
第一次迭代完成后,iter.000000 的文件夹结构如下,主要是 3 个文件夹:
/usr/bin/sh: 1: cd: can't cd to LiCl_DP_Tutorial_Example/chapter4
- 00.train 文件夹:主要是基于现有数据训练的多个 DP 模型(默认是 4 个);
- 01.model_devi 文件夹:使用 00.train 中得到的 DP 模型进行 MD 模拟,产生新的构型;
- 02.fp 文件夹:对选定的构型进行第一原理计算,并将计算结果转换成训练数据
首先,我们来查看 iter.000000
/ 00.train
。
iter.000000/00.train ├── data.init -> /data/bohrium-notebook/Proem/CH/LiCl_DP_Tutorial_Example/ex3 └── data.iters 1 directory, 1 file
- 文件夹 00x 包含 DeePMD-kit 的输入和输出文件,其中训练了模型。
- graph.00x.pb ,链接到 00x/frozen.pb,是 DeePMD-kit 生成的模型。这些模型之间的唯一区别是神经网络初始化的随机种子。
让我们随机选择其中之一查看,例如 000。
iter.000000/00.train/000 [error opening dir] 0 directories, 0 files
input.json
是当前任务的 DeePMD-kit 的设置。checkpoint
用于重新开始训练。model.ckpt*
是与模型相关的文件。frozen_model.pb
是冻结模型。lcurve.out
记录能量和力的训练精度。train.log
包括版本、数据、硬件信息、时间等。
然后,我们来查看iter.000000/01.model_devi
。
- 文件夹 confs 包含从您在 param.json 的“sys_configs”中设置的 STRU 转换而来的 LAMMPS MD 的初始配置。
- 文件夹 task.000.00000x 包含 LAMMPS 的输入和输出文件。我们可以随机选择其中之一,例如 task.000.000000。
conf.lmp
,链接到文件夹 confs 中的“000.0001.lmp”,作为 MD 的初始配置。input.lammps
是 LAMMPS 的输入文件。model_devi.out
记录在 MD 训练中相关的标签,能量和力的模型偏差。它是选择结构和进行第一性原理计算的标准。traj
存储LAMMPS MD轨迹。
通过查看 model_devi.out
的前几行, 您会看到:
想一下,我们将“trj_freq”设置为10,因此每10个步骤保存结构。
是否选择结构取决于其“max_devi_f”
。如果它介于“model_devi_f_trust_lo”
(0.08)和“model_devi_f_trust_hi”
(0.18)之间,DP-GEN 会将该结构视为候选结构。
对于0,10,20 和 30 步保存结构,其“max_devi_f”
均小于 0.08,所以不会被视为候选结构。
最后,我们来查看 iter.000000/02.fp
。
candidate.shuffle.000.out
记录将从最后一步 01.model_devi 中选择哪些结构。 候选的数量总是远远超过您一次期望计算的最大值。在这种情况下,DP-GEN将随机选择最多fp_task_max
结构并形成文件夹任务。rest_accurate.shuffle.000.out
记录了我们的模型准确的其他结构(max_devi_f
小于model_devi_f_trust_lo
),rest_failed.shuffled.000.out
记录了我们的模型太不准确的其他结构,这些结构通常是非物理的(大于model_devi_f_trust_hi
)。data.000
:经过ABACUS SCF计算后,DP-GEN 将收集这些数据并将其更改为 DeePMD-kit 所需的格式。在下一次迭代的“00.train”中,这些数据将与初始数据一起训练。
通过 cat candidate.shuffled.000.out | grep task.000.000000
, 你将会看到从task.000.000000中收集的候选构型:
Usage: grep [OPTION]... PATTERNS [FILE]... Try 'grep --help' for more information. cat: ./iter.000000/02.fp/candidate.shuffled.000.out: No such file or directory
在第一次迭代之后,我们检查 dpgen.log 的内容。
可以发现,在 iter.000000 中生成了 200020 个结构,其中候选构型21098个,挑选了 200 个结构进行ABACUS SCF计算,且全部成功收敛。
在所有迭代结束之后,我们来检查 LiCl_DP_Tutorial_Example/chapter4
的文件结构:
以及 dpgen.log
的内容:
可以发现,仅在三个iteration后accurate_ratio接近100.00 %。在 'iter.000002' 中收集了 9 个候选结构,小于param.json中fp_task_min
关键词指定的50。因此,模型不会在 iter.000003/00.train 中更新。
为了更直观监测迭代过程,我们提供了提供了一个名为max_devi_f.py的python脚本,用于统计每个iteration中所有构型max_devi_f的分布
至此,我们应该已经了解了如何使用 DP-GEN 生成和训练深度势模型,以及如何分析输出结果。
章节 5:LAMMPS 深度势能分子动力学研究
在训练好 DP 模型后,我们可以将其应用于 LAMMPS 软件中,以便更高效地模拟 LiCl 熔体的性质。这使得我们能够在大尺度和长时间尺度上研究 LiCl 熔体的结构、动力学和热力学性质,从而获得关于材料行为的更深入理解。
本章节目标:
学习完本课程后,你将能够:
- 能够利用循环方式进行 LAMMPS 模拟;
- 能够进行 LiCl 熔体的 NPT 和 NVT 计算。
5.1 下载教程资源
在本教程中,我们以 LiCl 熔体分子为例,构建训练数据并生成深度势模型。我们已经在 LiCl_DP_Tutorial_Example/chapter5 中准备了需要的文件。
首先,使用 tree
命令查看 LiCl_DP_Tutorial_Example/chapter5
文件夹。
./LiCl_DP_Tutorial_Example/chapter5 ├── 00.npt │ ├── licl.data │ └── licl.in └── 01.nvt ├── licl.in ├── msd_all_temperatures.png └── rdf_all_temperatures.png 2 directories, 5 files
licl.in
和licl.data
是 LAMMPS 的输入文件
本教程采用 DeePMD-kit(2.1.5)软件包中预置的 LAMMSP 程序完成。
5.2 NPT-MD模拟
我们在 ex4/iter.000002/01.train/* 文件夹中可以找到最终的4个 DP 模型。通过 dp compress
命令,可以将模型压缩,并命名压缩后的模型为 licl_compress_0.pb 到 licl_compress_3.pb。将压缩后的模型分别复制到 00.npt 和 01.nvt 文件夹。接下来,我们进行 LAMMPS NPT-MD 模拟,以预测 LiCl 熔体的密度。LiCl 熔体LAMMPS NPT-MD 的控制文件如下:

与 Chapter1 的 licl.in 相比,有几点需要解释:
variable a loop 4 pad
:创建一个名为a的变量,并通过loop命令在脚本中循环4次。变量 a 将在循环过程中依次取值 1, 2, 3 和 4。
variable b equal $a-1
:创建一个名为b的变量,其值等于a减1。这意味着在循环中,b的值将从0开始,直到3。
variable f equal $b*100
:创建一个名为f的变量,其值等于b乘以100。在循环过程中,f的值将是0、100、200和300。
variable t equal 900+$f
:创建一个名为t的变量,其值等于900加上f。在循环过程中,t的值将是900、1000、1100和1200。
replicate
2 2 2:表示沿x、y和z方向将原始系统复制一次。这将使得模拟体系由64原子增大至512原子。
`pair_style deepmd ./licl_compress_0.pb ./licl_compress_1.pb ./licl_compress_2.pb ./licl_compress_3.pb out_freq 100 out_file model_devit.out的文件,其中 $t 表示温度。
thermo_style custom step temp pe ke etotal press density lx ly lz vol
: 在thermo_style中增加了density,便于计算模拟体系的密度。
write_data licl$t.data
: 每次模拟结束时,将模拟体系的信息写入名为 licl$t.data
的文件中。
jump in.licl_npt
: 每次模拟结束后,脚本会清除之前的设置,并跳回到输入文件的开头,准备开始下一次模拟。
我们提供了一个名为 log_lammps.py 的 Python 脚本,可以从 LAMMPS NPT 中获取盒子边长和密度信息。
预测密度如下:
表5.1 不同温度下,LiCl熔体的计算密度和相应模拟盒子的边长。
T(K) | Density(g/cm3) | Lx |
---|---|---|
900 | 1.602 | 22.405256609375005 |
1000 | 1.562 | 22.596664576249935 |
1100 | 1.523 | 22.789268989874945 |
1200 | 1.485 | 22.981117881750063 |
5.3 NVT-MD 模拟
根据表 5.1 中 Lx 的数值调整 LAMMPS NPT-MD 模拟产生的 licl.data 文件中模拟盒子的边长。接下来,进行 LAMMPS NVT-MD 模拟,以预测 LiCl 熔体的结构信息和离子扩散系数。LiCl 熔体 LAMMPS NVT-MD 的控制文件如下:
variable a loop 4 pad
variable b equal <span class="katex"><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.6667em;vertical-align:-0.0833em;"></span><span class="mord mathnormal">a</span><span class="mspace" style="margin-right:0.2222em;"></span><span class="mbin">−</span><span class="mspace" style="margin-right:0.2222em;"></span></span><span class="base"><span class="strut" style="height:0.8889em;vertical-align:-0.1944em;"></span><span class="mord">1</span><span class="mord mathnormal" style="margin-right:0.03588em;">v</span><span class="mord mathnormal">a</span><span class="mord mathnormal" style="margin-right:0.02778em;">r</span><span class="mord mathnormal">iab</span><span class="mord mathnormal" style="margin-right:0.01968em;">l</span><span class="mord mathnormal">e</span><span class="mord mathnormal" style="margin-right:0.10764em;">f</span><span class="mord mathnormal">e</span><span class="mord mathnormal" style="margin-right:0.03588em;">q</span><span class="mord mathnormal">u</span><span class="mord mathnormal">a</span><span class="mord mathnormal" style="margin-right:0.01968em;">l</span></span></span></span>b*100

我们可以利用 chapter1 中提供的 Python 脚本,从 licl.rdf 和 licl.msd 中获得径向分布函数和离子自扩散系数。
预测径向分布函数如下:
表5.2 不同温度下,LiCl熔体的中Li-Li,Li-Cl和Cl-Cl离子对径向分布函数第一峰的位置。
T(K) | Li-Li | Li-Cl | Cl-Cl |
---|---|---|---|
900 | 3.605 | 2.345 | 3.675 |
1000 | 3.605 | 2.345 | 3.675 |
1100 | 3.605 | 2.345 | 3.745 |
1200 | 3.605 | 2.345 | 3.745 |
预测均方位移和离子扩散系数如下:
表5.3 不同温度下,LiCl 熔体的中 和 离子的扩散系数 。
T(K) | ||

900 | 8.48 | 3.28 |
1000 | 10.78 | 4.59 |
1100 | 12.54 | 5.96 |
1200 | 18.07 | 8.75 |
我们可以将计算结果和文献[1]进行比较,可以看到计算结构和文献基本吻合。
结语
在这项工作中,我们通过新训练的深度势(DPs)研究了典型碱金属氯化物 LiCl 的局部结构和输运特性。我们从从头算分子动力学(AIMD)计算中提取数据集,并用这些数据来训练和验证 DPs。我们在比 AIMD 更广泛的温度范围内进行了大规模、长时间的分子动力学模拟,以确认 DPs 的可靠性和通用性。我们证明了生成的 DPs 模型可以作为模拟碱金属氯化物的有力工具;DPs 还提供了与 AIMD 相当的准确性和与经验势相似的效率。使用 DPs 预测的部分径向分布函数和角分布函数与从 AIMD 得到的结果非常接近。这项工作为 DPs 可用于探索其他系统(包括氯化物混合物或完全不同的盐类)提供了信心。
