Dear Latif,

Thanks for reporting this. Unfortunately `pip` is not able to correctly install all dependencies of Larch. The way to go is to install those dependencies via `conda`.

Under Windows, this is achieved by running the script `GetLarch.bat` (https://raw.githubusercontent.com/xraypy/xraylarch/master/installers/GetLarch.bat). This script will download and install a minconda distribution, plus install Larch in it.

Seen you already have Anaconda installed, you could simply run the following commands from your Anaconda prompt:

conda install -yc conda-forge wxpython tomopy scipy matplotlib scikit-image scikit-learn pymatgen pycifrw
pip install wxmplot wxutils lmfit asteval pyshortcuts pyfai xraylarch

If this does not work, please, let me know. I have created a related Github issue in order to avoid such troubles in the future:

Best,
Mauro
