Hello Xilingyi,
I faced the same issue. How did you fix it? I would appreciate your help.

My version of ase has been upgraded to 3.22. Then, catkit can run. At 2021-11-19 11:23:08, "hanao2" ***@***.***> wrote: Hello Xilingyi, I faced the same issue. How did you fix it?

Hello,
I am also facing that issue. My ase is upgraded to 3.22.1 version.
Is there anything else that you have changed to fix this error?

Maybe You can install the latest version of anaconda3, then install catkit through pip of anaconda prompt. At 2022-01-27 01:53:16, "melkoz" ***@***.***> wrote: Hello, I am also facing that issue.

@melkoz I had to downgrade ase to 3.17.0 to get catkit 0.5.4 to work. The last update of catkit was released in 2018, and this is when ase 3.17.0 was released. Anything before gets flagged by catkit and anything after returns the '_cell' error for me.

Hi all,

Try to install CatKit directly from this github repo and not from 'pip install catkit'.

The ._cell issue was fixed a while back, but I don't have permission to update the pypi entry.

Hi, I installed by "pip install git+https://github.com/SUNCAT-Center/CatKit.git", I keep run into the issue of AttributeError: 'Gratoms' object has no attribute '_cell'. Is there anything else that you have changed to fix this error?
