How to deal with "Numpy is not available"

[freemank1224]

After following the installation instruction, when I am running the example file "inference.ipynb", it can successfully fetched the files (Fetching 10 files: 100%|██████████| 10/10 [00:00<00:00, 20097.29it/s]). BUT, then, it show some error message:

RuntimeError: Numpy is not available

That's a very strange issue. @freemank1224, did you check if the NumPy library is installed?

[yuezewang]

You can first try to confirm whether numpy is installed and used correctly in your environment, and tell us your numpy version (Perhaps there is already an incompatible version of numpy in your environment)

I have a similar issue, when running 'python app.py', I get the same runtimeerror. I have numpy 2.1.2 installed in my environment. I tried downgrading to 1.10.0 and 1.3.0. Both did not work either.

After deleting the original virtual env and recreate a new one, I have solved this issue.

Similar error for me. It helped to run pip install numpy==1.24.1 which saw it uninstalled 2.1.3 and installed 1.24.1 then it worked.
