Installation Issues

[timebis]

Hi guys,

Thanks again for the work made with Flexmeasures.
I'm currently trying to play with the project.

Here is a share of the issues I got during the installation process :

Difficulties to pip install flexmeasures with Python3.10 (both with ubuntu and Windows 11)

I manage to make it work with python3.9.13

Difficulties with the package "PIL" or "Pillow"

I finaly made it work with python3.9 -m pip install -U pillow==9.0.1

Did I miss something ?

Hi @timebis

About the first issue: we know that FlexMeasures 0.11 is not supporting 3.10 yet ― (and we say so). I believe the latest dependency management PRs (#476, #494) should help with that, once 0.12 is out.

But you figured out how to move forward!

I can't make much of the pillow problem. pillow is part of our requirements.

I notice that in the end, your computer says that pillow already exists in/usr/lib. Plus, and that is a guess, it seems you are not using a virtual environment. The cleanest way to work is always in a virtual environment. Maybe that will be more straightforward?

I ran this:

mkvirtualenv --python python3.9  fm-env-39-testinstall
pip install flexmeasures

and that worked well.

It seems re-installing pillow is one prescribed remedy against this problem (see here, for example). Installing it fresh in a virtual environment thus avoids this pitfall :)

Virtual environments are awesome in general, for all sort of reasons, so if you’re not using them already, you should :)

Curious to hear if that would make this problem go away :)

Excited to learn if you have a use case in mind - let us know if you do and we can discuss how FlexMeasures could help!

Thanks for your answer !

Indeed I don't have the venv reflex when I am working without my IDE. It solved the issue : pip install flexmeasures worked perfectly :)

Sure, I will keep you informed.
