Questions about the use of DeePKS

[yycx1111]

Details

I have installed deepks and abacus on my local machine. I met some problems with package and function versions in the case of running a single water molecule in deepks. Here are a few of my questions, since I didn't get feedback for asking questions in the deepks community. I ask the same questions in abacus.

1. What version of pyscf is compatible with deepks? What can be done about the following problems?

2. Is deepks still being updated? Cause I've encountered some problems that suggest that the function or package used is old and may no longer work.

3. Is there a container image with deepks readily available on the Bohrium platform?

Have you read FAQ on the online manual http://abacus.deepmodeling.com/en/latest/community/faq.html

• Yes, I have read the FAQ part on online manual.

@WHUweiqingzhou Any comments? I do think a hands-on tutorial for deepks-abacus installation along with deepks notebook is needed

Second it. We will consider this.

@yycx1111 It seems there are issues with matching deepks-kit with the newest pyscf version. You can use deepks-kit with ABACUS instead.

Here's a way to use ABACUS+deepks in conda environment:

conda create -n abacus+deepks python=3.12 numpy=1.26.0 scipy h5py ruamel.yaml=0.17.21 paramiko abacus "libblas=*=*mkl" mpich -c conda-forge

conda activate abacus+deepks

# Install pytorch, the cuda version depends on your machine
conda install pytorch torchvision torchaudio cpuonly -c pytorch # cpu version
conda install pytorch torchvision torchaudio pytorch-cuda=12.4 -c pytorch -c nvidia # gpu version

# use develop branch
pip install git+https://github.com/deepmodeling/deepks-kit@develop

Thank you for your reply. But I have been experiencing problems with network connections or failing to connect to the site when creating the environment, and I still have problems with connection errors even after switching to the Tsinghua source. Do you have any suggestions on how to create an environment?
The problems are like this:
CondaHTTPError: HTTP 000 CONNECTION FAILED for url http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/linux-64/libmagma-2.8.0-hfdb99dd_0.conda

An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.

This looks like a problem with your network setup. Maybe you should check things like your network environment and proxy settings.

Ahh, I’ve made a mistake. For cpu version, try

conda install pytorch torchvision torchaudio cpuonly -c pytorch
