Hello kwant users,
It has been quite some time since I last saw activity on this forum—perhaps
AI assistants have become everyone's first stop for troubleshooting!
Nevertheless, I am hoping to get some advice from the community on an issue
I have encountered.
I have a Gemini Pro subscription and frequently use Google Colab, which now
has Gemini integrated directly into the notebook environment. One of the
reasons I would like to use Kwant in Colab is to take advantage of the
built-in AI assistance while developing and analyzing Kwant-based
simulations.
However, I am experiencing difficulties using Kwant in Google Colab. Kwant
appears to install successfully, and the installation is recognized by the
environment, but importing Kwant from within a notebook cell results in a
ModuleNotFoundError.
The environment is Google Colab with Python 3.11.11 and Kwant 1.5.0
installed from conda-forge. During the process, I also encountered a Python
version pinning conflict involving Python 3.12 versus the installed Python
3.11.11, which may or may not be related.
What is confusing is that Kwant seems to be present and accessible at the
environment level, yet it remains unavailable from within the notebook
kernel itself. This suggests a possible mismatch between the environment
where Kwant is installed and the interpreter used by the notebook.
Has anyone encountered a similar issue when using Kwant with Google Colab?
Is there a known compatibility problem with recent Colab environments, or a
recommended way to ensure that the notebook kernel is using the correct
environment?
Any guidance would be greatly appreciated.
Best
Adel
