Hello,

I tried following commands to install napari-wsireg in a separate environment on my Windows 10 machine:

conda create -n nap-wreg python=3.9 conda activate nap-wreg pip install wsireg pip install napari-wsireg pip install "napari[all]"

Everything went fine, until I opened Napari and clicked on Plugins > napari-wsireg. I got a bunch of errors and I am not sure if it's a library issue or something else. Could you please help? Here is the full traceback in case you want to see:

@ved-sharma Yes this definitely looks like an issue with ITK's python package. I'll investigate. Thank you for bringing this to my notice!

@ved-sharma There appears to be an upstream issue with ITK in windows that I'll let them know about.

As a fix, can you try from the terminal:

pip uninstall itk-elastix itk
pip install itk==5.2.0 itk-elastix==0.13.0

then re-try napari-wsireg. It worked for me on Windows 10.

ved-sharma commented 2 years ago

Yes, that worked. Thank you so much!
