dpdata package

class dpdata.LabeledSystem(file_name=None, fmt='auto', type_map=None, begin=0, step=1, data=None, convergence_check=True, **kwargs)[source]

Bases: System

The labeled data System.

For example, a labeled water system named d_example has two molecules (6 atoms) and nframes frames. The labels can be accessed by

d_example[‘energies’] : a numpy array of size nframes
d_example[‘forces’] : a numpy array of size nframes x 6 x 3
d_example[‘virials’] : optional, a numpy array of size nframes x 3 x 3

It is noted that

The order of frames stored in ‘energies’, ‘forces’ and ‘virials’ should be consistent with ‘atom_types’, ‘cells’ and ‘coords’.
The order of atoms in every frame of ‘forces’ should be consistent with ‘coords’ and ‘atom_types’.

Parameters:

file_namestr

The file to load the system

fmtstr

Format of the file, supported formats are

auto: infered from file_name’s extension
vasp/xml: vasp xml
vasp/outcar: vasp OUTCAR
deepmd/raw: deepmd-kit raw
deepmd/npy: deepmd-kit compressed format (numpy binary)

qe/pw/scf: Quantum Espresso PW single point calculations. Both input and output files are required. If file_name is a string, it denotes the output file name. Input file name is obtained by replacing ‘out’ by ‘in’ from file_name. Or file_name is a list, with the first element being the input file name and the second element being the output filename.
siesta/output: siesta SCF output file

type_maplist of str

Maps atom type to name. The atom with type ii is mapped to type_map[ii]. If not provided the atom names are assigned to ‘Type_1’, ‘Type_2’, ‘Type_3’…

append(*systems)[source]

Append systems or MultiSystems to systems.

Parameters:

*systemsSystem: The system to append

check_atom_names(system)[source]: Make atom_names in all systems equal, prevent inconsistent atom_types.

correction(hl_sys: MultiSystems)[source]

Get energy and force correction between self (assumed low-level) and a high-level MultiSystems. The self’s coordinates will be kept, but energy and forces will be replaced by the correction between these two systems.

Parameters:

Returns:

corrected_sysMultiSystems: Corrected MultiSystems

Notes

This method will not check whether coordinates and elements of two systems are the same. The user should make sure by itself.

Examples

Get correction between a low-level system and a high-level system:

>>> low_level = dpdata.MultiSystems().from_deepmd_hdf5("low_level.hdf5")
>>> high_level = dpdata.MultiSystems().from_deepmd_hdf5("high_level.hdf5")

class dpdata.System(file_name=None, fmt='auto', type_map=None, begin=0, step=1, data=None, convergence_check=True, **kwargs)[source]

Bases: MSONable

The data System.

A data System (a concept used by deepmd-kit) contains frames (e.g. produced by an MD simulation) that has the same number of atoms of the same type. The order of the atoms should be consistent among the frames in one System.

For example, a water system named d_example has two molecules. The properties can be accessed by

d_example[‘atom_numbs’] : [2, 4]
d_example[‘atom_names’] : [‘O’, ‘H’]
d_example[‘atom_types’] : [0, 1, 1, 0, 1, 1]
d_example[‘orig’] : [0, 0, 0]
d_example[‘cells’] : a numpy array of size nframes x 3 x 3
d_example[‘coords’] : a numpy array of size nframes x natoms x 3

It is noted that

The order of frames stored in ‘atom_types’, ‘cells’ and ‘coords’ should be consistent.
The order of atoms in all frames of ‘atom_types’ and ‘coords’ should be consistent.

Restrictions:

d_example[‘orig’] is always [0, 0, 0]
d_example[‘cells’][ii] is always lower triangular (lammps cell tensor convention)

DTYPEStuple[DataType]: data types of this class

perturb(pert_num, cell_pert_fraction, atom_pert_distance, atom_pert_style='normal')[source]

Perturb each frame in the system randomly. The cell will be deformed randomly, and atoms will be displaced by a random distance in random direction.

Parameters:

pert_numint

Each frame in the system will make pert_num copies, and all the copies will be perturbed. That means the system to be returned will contain pert_num * frame_num of the input system.

cell_pert_fractionfloat

A fraction determines how much (relatively) will cell deform. The cell of each frame is deformed by a symmetric matrix perturbed from identity. The perturbation to the diagonal part is subject to a uniform distribution in [-cell_pert_fraction, cell_pert_fraction), and the perturbation to the off-diagonal part is subject to a uniform distribution in [-0.5*cell_pert_fraction, 0.5*cell_pert_fraction).

atom_pert_distancefloat

unit: Angstrom. A distance determines how far atoms will move. Atoms will move about atom_pert_distance in random direction. The distribution of the distance atoms move is determined by atom_pert_style

atom_pert_stylestr

Determines the distribution of the distance atoms move is subject to. Avaliable options are

‘normal’: the distance will be object to chi-square distribution with 3 degrees of freedom after normalization.
The mean value of the distance is atom_pert_fraction*side_length

‘uniform’: will generate uniformly random points in a 3D-balls with radius as atom_pert_distance.
These points are treated as vector used by atoms to move. Obviously, the max length of the distance atoms move is atom_pert_distance.

‘const’: The distance atoms move will be a constant atom_pert_distance.

Returns:

perturbed_systemSystem: The perturbed_system. It contains pert_num * frame_num of the input system frames.
