No module named 'blosc.blosc_extension' when importing radio - module

Question

I created an environment (radIOenv) in Anaconda.
And I typed python -m pip install git+https://github.com/analysiscenter/radio.git.
When i type import radio or from radio import CTImagesBatch I get the following error : ModuleNotFoundError: No module named 'blosc.blosc_extension'
How can I solve this problem ?
Here is the full output :

I've had an issue in Anaconda before where I've accidentally installed the C version of Blosc rather than the Python version. I doubt this is your issue but the Python version is installed with conda install -c conda-forge python-blosc
