AttributeError:

instead of file "/opt/mamba/envs/deepks/lib/python3.10/site-packages/deepks/utils.py", line 138

    res = yaml.safe_load(fp)

The safe_load and safe_dump functions used in deepks/utils.py has been deprecated since yaml 0.15.0. See https://yaml.readthedocs.io/en/latest/api/. We should think about update the supported version of yaml package.
