[Simnibs-discuss] [UNCLASSIFIED] Unable to install simnibs 4.0

Hi Oula,

Unfortunately, I am receiving the same error despite your instructions. See attached my anaconda script.
Apologies.

Best,
Aidan

Hi Aidan,

Sorry I copied the wrong link in. Please download the .yml file first,
i.e., save the file from this link:

https://github.com/simnibs/simnibs/releases/download/v4.0.0/environment_win.yml<https://github.com/simnibs/simnibs/releases/download/v4.0.0/environment_win.yml>

to your computer.

Then use conda and the file above to create the simnibs environment:

conda env create -f "%USERPROFILE%\Download\environment_win.yml"

assuming the .yml file is in your Download folder. After that activate
the environment by calling:

conda activate simnibs_env

and finally install the simnibs wheel (here's where I made a mistake in
the previous email):

pip install
https://github.com/simnibs/simnibs/releases/download/v4.0.0/simnibs-4.0.0-cp39-cp39-win_amd64.whl<https://github.com/simnibs/simnibs/releases/download/v4.0.0/simnibs-4.0.0-cp39-cp39-win_amd64.whl>

then try calling (with the environment active):

python

import simnibs

Best,
Oula
