## Software Architecture

It is recommended to use Python 3.10 or higher. Older versions might cause type errors.
We also recommend using GPUMD version 3.9.5 or higher.

 
## Usage

Modify the `vim ~/.NepTrain` file to change the pseudopotential file path.
If this file doesn't exist, simply run `NepTrain init` once to generate it.


 
### Creating Training Set (Optional)
Generate a perturbation training set for structures or structure files.

For example, apply a 0.03 lattice distortion and 0.1 atomic perturbation:
```sh
NepTrain perturb ./structure/Cs16Ag8Bi8I48.vasp --num 2000 --cell 0.03 -d 0.1  
NepTrain select perturb.xyz -max 100  
```

### 1. Initialization
First, initialize NepTrain. This will create a submission script in the current directory:
```sh
NepTrain init slurm
```

### 3. Submit Job
After modifying the submission script and job configuration, you can submit the job by running the following command on a login node:
```sh
NepTrain train job.yaml
```
For running the job in the background, use `nohup`
```sh
nohup NepTrain train job.yaml &
```
If the job is interrupted, there will be a  `restart.yaml` file in the directory. To resume the job, run:
```sh
NepTrain train restart.yaml
```
