v2.0.0-alpha.0

The very first alpha release of deepmd-kit version 2.0.0. It includes the following new features

• Model compression
• New descriptor: three body embedding
• Hybridization of descriptors
• Long-range modification
• Type embedding (under development)
• Training and inference the dipole (vector) and polarizability (matrix). (under development)
• Split of training and validation dataset. (under development)
• ROCm device support (under development)

Enhancements

• More efficient training: all customized OPs are implemented with GPU.
• Parallel training with multiple GPU support (under development)

Improvement of the code for developers

• Supports version of the model. Easily check model compatability
• Clear and pythonic python interface
• C++ API that can be tested independently
• OP supports multi-device.

Bug fixings:

• remove using namespace std. Solves compiling compatability problem.
• added deepmd namespace for the C++ API

v1.3.3

Bug fixing:

• Fix lammps memory leak when initialized pair_style deepmd for multiple times. #392
• Fix GPU memory issues. #393 #407 #424

v1.3.2

Improvements:

• Compiling with Cuda 11.0 and 11.1 #390

Bug fixings:

• Fix stress tensor bug of ASE interface #338

v1.2.4

Bug fixings

• Fix several compiling issues of v1.2.3

v1.2.3

New feature:

• added tool to convert a v1.2 compatible model to v1.3 compatible model.

Bug fixing:

• neighbor list bug in the GPU implementation.

v1.3.1

Bug fixing:

• Compulsory label requirement if the corresponding prefactor is set to non-zero. The current behavior is when then label is missing, the corresponding term does not appear in the loss function
