How to solve the pytorch RuntimeError: Numpy is not available without upgrading numpy to the latest version because of other dependencies

stackoverflow.com › questions › 71689095 › how-to-solve-the-pytorch-runtimeerror-numpy-is-not-available-without-upgrading

Getting same error for numpy 2.0 as of March 18th 2025.

Current solution is to install the latest version of numpy 1 (1.26.4) instead:

Copypip install "numpy<2"

You will likely have to restart the kernel afterwards.

This will be easily solved by upgrading numpy.... When I face this error, that time numpy version 1.22 was installed.... I update version to 1.24.1 using this command

Copypip install numpy==1.24.1

Ok. I’ve had this one before. I think (I’m only hypothesizing) that you have to refer to Numpy as np forever after. I think. You’ve referred to it as from_numpy. Maybe I’m just running the wrong track and the error is something else. If this doesn’t work, I’m super sorry, I’m under 15 years of age. …

Ok after tracking the error log I found:

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.0.0 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

Apparently numpy released a new version (numpy 2.0.0) just two day ago (2024/06/17) and pip by default installs the new version which is not compatible with pytorch yet as I assume.

Downgrading numpy to the last stable version of numpy v1 using the following command fixed the issue:

pip install numpy==1.26.4

At least in Google Colab I was able to solve this issue by running (after installing xla):

!pip install -U numpy

Not completely sure it will help in any context

This is an issue with the version mismatch. Currently the pytorch version 1.12.1+cu113 is compatible with numpy version 1.21.6.

I don't know why this occurs. But keep checking the version in google colab and you can possibly make torch work locally.

PyTorch does not implement __array_function__ or __array_ufunc__. Under the hood, the Tensor.__array__() method returns a NumPy ndarray as a view of the tensor data buffer. See this issue and the __torch_function__ implementation for details.
