FYI: installing expyriment with recent Anaconda Python3

[Christophe Pallier]

Hi,

Trying to install expeyriment wih Anaconda Python3.9 under Linux,  I encountered compilation issues.

A workaround was to create an environment (https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html) to use Python 3.7:   

    conda create --name expyriment python=3.7

    conda activate expyriment
    pip install expyriment[all]

Then no compilation was needed.
