Hi, thanks for your work. A long time ago I worked about IA and trading, but never found a way to incorporate it too fractured. I have this error despite I followed your guideline, please could you help me?

Remove and reinstall fixed it

`rm -rf .env/lib/python3.8/site-packages/numpy*

pip install --force-reinstall --no-deps numpy==1.22.0`
