Error at Localize module launch after installing GPUFit on a pip install

[Christophe Leterrier]

I tried to install Picasso with the pip install method in an Anaconda environment under WIndows 10. I did as per the readme file:

Via PyPI
Open the console/terminal and create a new conda environment: conda create --name picasso python=3.8
Activate the environment: conda activate picasso
Install Picasso package using: pip install picassosr
You can now run any Picasso function directly from the console/terminal by running: picasso render, picasso localize, etc.

Then I installed the latest GPUFit wheel (https://github.com/gpufit/Gpufit/releases/tag/v1.2.0, cublas version) using pip install [PATH_TO_GPUFIT_WHEEL]

Output was:

Processing c:\users\chris\christo\processing\gpufit_1.2.0_cublas_build202110131846\python\pygpufit-1.2.0-py2.py3-none-win_amd64.whl
Requirement already satisfied: NumPy>=1.0 in c:\users\chris\.conda\envs\picasso\lib\site-packages (from pyGpufit==1.2.0) (1.19.2)
Installing collected packages: pyGpufit
Successfully installed pyGpufit-1.2.0

It created the two folders pygpufit and pyGpufit-1.2.0.dist-info in the environment C:\Users\chris\.conda\envs\picasso\Lib\site-packages

Now when I launch the Localize module picasso localize I get the following error:

whereas the file at this path is indeed existing.

Hi Christophe,

Apologies for the late reply. We will try solving this issue with the next Picasso release. Sorry for inconvenience.

Best wishes,
Rafal

Hi Christophe,

I have looked into the problem and I noticed that if you choose the non-cublas version, everything works fine. Again, I would like to apologise for taking such a long time to reply.

Bests,
Rafal
