module 'numpy' has no attribute 'asscalar' about riskfolio-lib HOT 16 CLOSED

which version of Riskfolio-Lib ?

from riskfolio-lib.

I'm using version 4.03.

from riskfolio-lib.

I think you must uninstall and reinstall because I removed np.asscalar from all code when numpy gave the deprecation warning on that function.

from riskfolio-lib.

odd, tried uninstall and reinstall and still getting the error on import.

import riskfolio.Portfolio as pf

from riskfolio-lib.

No, now is just import riskfolio as rp, import riskfolio.portfolio as pf is from very old versions

from riskfolio-lib.

tried import riskfolio as rp and still get the Numpy error.

from riskfolio-lib.

Which is your Python version?

from riskfolio-lib.

I did double check after uninstalling and it gave me a no module not found error. Reinstalled and tried to import with import riskfolio as rp and get the numpy error.

from riskfolio-lib.

Python version 3.9.6

from riskfolio-lib.

on Mac M1 version 13.2.1

from riskfolio-lib.

Are you using anaconda ?

from riskfolio-lib.

no, not using anaconda.

from riskfolio-lib.

Use anaconda, for scientific python use anaconda at least on Mac. I also have a M1 and I don't have problems. But install rosetta and download the normal version of anaconda, not the ARM version.

from riskfolio-lib.

I'll try anaconda on a test machine, but in the interim I thought I'd share the following.

File /Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/astropy/units/quantity_helper/function_helpers.py:116, in

110 # The following are not just unsupported, but so unlikely to be thought
111 # to be supported that we ignore them in testing. (Kept in a separate

As I told you, if you look on the code, Riskfolio-Lib doesn't use np.asscalar. It's a problem with your Python configuration. If you don't use a scientific Python distribution it's not a Riskfolio-Lib issue.
