conda cannot solve current environment.yml (windows x64)

[soeroesg]

Hi, thanks for your tool! I was trying to set it up but conda fails to solve the dependency conflicts in the current environment.yml

I tried this command: conda env create -f environment.yml

Hi thanks for trying out the tool! What error message are you getting?

It starts like below and goes on for hundreds of similar errors

What conda version do you have installed on your machine? This might be solved by updating the conda version:

conda update --all

Also, I am using the libmamba solver for conda. Possibly this helps as well:

conda install -n base conda-libmamba-solver
conda config --set solver libmamba
