[Crashtest72]

Good morning,

I am trying to install python occ core 0.18.1 under W7 64: -->anadonda navigator 1.9.2 -->python 3.6 -->Qt creator 4.7.0 based on qt5.11.1

I tried to install python occ with the conda link below: conda install -c conda-forge -c dlr-sc -c pythonocc -c oce pythonocc-core==0.18.1

I launch it by the terminal launched under the anaconda navigator

I get the following error each time I try:

""Executing transaction: failed ERROR conda.core.link:_execute(502): An error occurred while uninstalling packag e 'defaults::anaconda-5.2.0-py36_3'. PermissionError(13, 'Accès refusé')""

Is there anybody to help me please ?? I have tried several way even with the source code to build, nothing works :((((

Thanks ahead.

Is just possible to know if at least the softwares I use are compatible with the installation of python occ?

[efirvida]

Hi I have a similiar issue, I opened in pythonocc-demos. I will close it there

After conda install -c conda-forge -c dlr-sc -c pythonocc -c oce pythonocc-core==0.18.1

conda env cannot be used any more.

Even for conda list, I get

system cannot find the path specified

Any suggestions what causes this?

Hi, i came accross withe the same issue few weeks ago but in different circumstance. Check my answer here. It has something to do with the files in conda Script folder.

[johannesmichael]

Hi, @johanesmikhael this really helped me solving some issues. I realized, that only in the not working env there were activate, activate.bat, conda, .... files included, (except from the Anaconda3 folder itself). I removed them, and then this conda env was working again. Only issue I face now, is that I can't add this kernel to the jupyter notebook. Still trying to find the problem here.

Edit: I removed some nb_kernel files and now, jupyter is working again with this env
