Issue:
Why does Python configuration freeze at the 'Installing pip dependencies...' step?

Conda Troubleshooting
This seems to be a Miniconda issue when building the PLS_Toolbox virtual environment for the first time. It might also be worth noting we have only seen this on Windows machines so far (if you are running something different and encounter this, please let us know). Here is a workaround for those who have this issue in MATLAB:
- Get path to config_pyenv.m.
- From the MATLAB Command Window, type in the command
which config_pyenv
and enter. - Copy output of this command.
- From the MATLAB Command Window, type in the command
- Open Anaconda Powershell Prompt (Windows) or Terminal (macOS or Linux).
- Type
cd 'PASTE_OUTPUT_FROM_STEP_1_HERE'
and enter. - Type
cd ymls
and enter. - Type
conda env create -f pls_toolbox_<platform>_38.yml
and enter. This may take several minutes depending on your machine.- <platform> is one of either mac, windows, or linux, depending on what OS you are running.
- If you receive
CondaValueError: prefix already exists
while doing this step, the environment must be deleted in order to continue properly. One can do this by typing the commandconda remove -n pls_toolbox_<platform>_38
. Then repeat Step 5.
- Next, type
conda activate pls_toolbox_<platform>_38
and enter. - Type
python
and enter. - Type
import sys
and enter. - Type
sys.executable
and enter. Copy this output. - Go back to the MATLAB command window. Type in
pyenv('Version','PASTE_OUTPUT_FROM_STEP_9_HERE','ExecutionMode','InProcess')
and enter. - We then urge to rerun
config_pyenv
to see if this fixed the issue.
