Re: [scipion-users] Scipion3 failed installation: OpenCV not found - can't install xmipp

[Grigory S. <sha...@gm...>]

Hi Karl,

there are two problems:

1) you created a conda environment then activated it and then used scipion
installer to create virtualenv inside conda env. This is a very weird
setup. If you want to use conda, please follow the installation
instructions. You only need to source conda itself (do not create env or
activate it), and then run the installer with specific options.
2) you are using cuda 11.1 which is not supported by xmipp. You need to
have cuda 10.x or disable CUDA during xmipp installation.


Best regards,
Grigory
