<p class="MsoNormal">Hi Aidan,<br>
<br>
Sorry I copied the wrong link in. Please download the .yml file first,<br>
i.e., save the file from this link:<br>
<br>
<a href="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</a><br>
<br>
to your computer.<br>
<br>
Then use conda and the file above to create the simnibs environment:<br>
<br>
conda env create -f "%USERPROFILE%\Download\environment_win.yml"<br>
<br>
assuming the .yml file is in your Download folder. After that activate<br>
the environment by calling:<br>
<br>
conda activate simnibs_env<br>
<br>
and finally install the simnibs wheel (here's where I made a mistake in<br>
the previous email):<br>
<br>
pip install<br>
<a href="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</a><br>
<br>
then try calling (with the environment active):<br>
<br>
python <br>
<br>
import simnibs<br>
<br>
<br>
Best,<br>
Oula<br>
<br>
