Error Occurs when Running the Online Contextual Bandits Tutorial about contextualbandits HOT 4 CLOSED

There's a note about it in the readme installation instructions. In short: either update numpy, or install without pep517.

Hi @david-cortes ,

Thank you for your speedy reply! I uninstalled the contextualbandits package and reinstalled it with the command given in the tutorial. But I still got the same error.

python -m pip uninstall contextualbandits
python -m pip install --no-use-pep517 contextualbandits

Any suggestions?

Note: to make sure that I successfully reinstalled the package. I uninstalled the package, and then I restarted the jupyter server, confirming the package has been successfully removed. After that, I installed the package again according to the command in the readme file.

That's weird. Perhaps updating numpy to >= 1.20.0 would do (might also need updating cython too). Alternatively, you could also install it without pip with python setup.py install, or if you know how to create installable packages, perhaps modifying the requirements.txt by changing numpy to numpy<=1.19.0.

Hi @david-cortes ,

I upgraded my numpy version to 1.20.1 and it works. Thank you very much for your help!
