RuntimeError: Numpy is not available

Question

I am getting this error RuntimeError: Numpy is not available, while trying to run the following line of code:

img = torch.from_numpy(np.array(pic, mode_to_nptype.get(pic.mode, np.uint8), copy=True))

Is there a way to solve this without the need to change python version?

Note: my python version is 3.10.

This topic seems to be about the same issue, yet it hasn't got any good answer stackoverflow.com/questions/71689095/… — Mateo Vial

Is there a way to downgrade the python version without re-installing it all over again? Because I am afraid if I uninstall python all my installed packages will be removed and I will re-install many of them again. — Ala BR

please use anaconda to manage these package error; trust me its the best — Prajot Kuvalekar

Thanks, it was fixed with anaconda, maybe because anaconda uses python 3.9 instead of 3.10 — Ala BR

Although, this is an old question.

We are still getting this warning for numpy 2.0.

So, the solution as of August 14th 2024 be:

pip install numpy==1.26.4

pip install "numpy<2" =))) I like this solution more, as your comment in stackoverflow.com/questions/71689095/…

Just had the same problem running torchvision with python3.12; torch docs recommend using a version between Python 3.8 - 3.11.

Create a new environment running on python3.9, I'm using MacOS with Homebrew so command is:

python3.9 -m venv /path/to/your/new/virtual/environment

Once this environment was created I installed torchvision with a specific numpy version lower than 2.0.0

# Install lower version of numpy to avoid compatibility issues.
pip install numpy==1.24.1
pip install torch torchvision
