I am attempting to implement a BNN posted on GitHub in the link attached: https://github.com/yucenli/bnn-bo.

In the README section, I tried running code “conda env create -f environment.yml”, which is supposed to be the part where I create a new conda environment. However, my terminal returned the following error message:

PS C:Usersliuna> conda env create -f environment.yml

I have also attempted codes like “conda update conda” to ensure everything’s up to date, and it looks like some packages aren’t compatible or do not exist but this entire environment should be created fairly recent and I believe it has nothing to do with specific versions (i.e. if anything, wouldn’t the versions above be just old but not necessarily nonexistent?). I have looked up this issue and do not think I see a similar problem being actually answered. Perhaps there is a straightforward fix to this. Thanks in advance.

Mentioned above (e.g. attempted running “conda update conda”.)
