NumPy Installation On Windows Operating System You can download the required version of python from python.org. Once python is installed successfully, open command prompt and use pip to install numpy.
This NumPy release is the result of 581 merged pull requests contributed by 175 people. The Python versions supported for this release are 3.7-3.9, support for Python 3.10 will be added after Python 3.10 is released.
To solve the error "Could not build wheels for numpy", run the pip install --upgrade pip command to upgrade your pip version and rerun the pip install numpy command. Copied! The most common cause of the error is having an outdated version of pip .
The Python "ModuleNotFoundError: No module named 'numpy'" occurs when we forget to install the numpy module before importing it or install it in an incorrect environment. To solve the error, install the module by running the pip install numpy command.
Python 3.9 came out 3 days ago (today - Oct 8, 2020). It doesn't have wheels for numpy yet.
See here
But it’s so soon after 3.9’s release, many packages don’t have wheels for Python 3.9 yet. For example, as of October 6th neither the PyPI file listing for NumPy (a Pandas dependency) nor the file listing for Pandas show Python 3.9 wheels. You can, of course, compile these packages from source, assuming they work out of the box with Python 3.9–but that takes a bunch more effort (setting up compilers) and time.
Is there a specific reason you really need 3.9 right now?
If not, I would stick with 3.8 or even 3.7 for now. Upgrading later should be super easy.
