NumPy issue during install

[philipnenni]

Can I get some help on resolving this issue? thanks in advance I'm a python newbie.

ERROR: Cannot install numpy==1.21.6 and numpy==1.22.3 because these package versions have conflicting dependencies.

  The conflict is caused by:
      The user requested numpy==1.22.3
      The user requested numpy==1.21.6

It would be helpful to say what command you ran to get that error message @philipnenni

[philipnenni]

I was trying to install sparse so the command I used was 'pip install sparse'
I also tried in PyCharm and limiting the version of NumPy but neither option worked.

[rgommers]

The only requirements in sparse are (from https://github.com/pydata/sparse/blob/master/requirements.txt):

numpy>=1.17
scipy>=0.19
numba>=0.49

So this seems unlikely to be the cause. Can you provide the complete output of pip install sparse, and also say how you installed Python and whether or not you are working in a virtualenv?

[philipnenni]

I think you are right... I'm still getting used to reading the logs and whatnot. I'm using Python 3.10.7 on windows.
Here is the full output.

  To fix this you could try to:
  1. loosen the range of package versions you've specified
  2. remove package versions to allow pip attempt to solve the dependency conflict

Using cached scipy-1.9.1.tar.gz indicates that pip is trying to build SciPy from source. What is happening here is that there's no SciPy wheel for 32-bit Windows at https://pypi.org/project/scipy/1.9.1/#files.

You're not going to be able to resolve that easily. If you are new to Python and can start over, the best thing is to get rid of your 32-bit install completely, and install a 64-bit Python. If you don't know which one, I recommend the 64-bit Windows installer of Anaconda at https://www.anaconda.com/products/distribution. It already comes with NumPy, SciPy, Numba etc. pre-installed (maybe even sparse, no sure). Otherwise, if you prefer the python.org installer, also there 64-bit is recommended: https://www.python.org/downloads/release/python-3107/

Cool! Thanks for the help. Sorry about my lack of experience and understanding of the logs.

[rgommers]

No worries at all!

Thanks @rgommers for replying to this much faster than I could. I appreciate it!
