Error while trying the basic example

[EtienneT]

Installed using pip. Tried the very simple example from the readme, but got this error when importing the package.

[rudrashisgorai]

Did you use pip install polyfuzz or pip install polyfuzz[fast] ?

[EtienneT]

@rudrashisgorai I did the following sequence. One thing to note, I am on Windows. Not sure if it change anything:

conda install -c conda-forge sparse_dot_topn
pip install polyfuzz
pip install polyfuzz[all]

[EtienneT]

Did the exact same setup in WSL 2 in Ubuntu, got the exact same error.

[MaartenGr]

Which version of numpy do you have? I have noticed some issues with that. Could you try it out with numpy v1.20 or higher?

[EtienneT]

Installed numpy 1.20.3, and running the basic example works now.

But I get the following errors when using pip:

polyfuzz 0.3.2 requires numpy<=1.19.4,>=1.18.5, but you have numpy 1.20.3 which is incompatible.

[MaartenGr]

Numpy was upgraded to the new version to be compatible with the package. If in a new environment, you try out the new version of PolyFuzz, you should have no issues.

If it does not work out, please let me know!
