@QGN123 can you please add how you installed Python, NumPy and PyWavelets?

rgommers commented 1 year ago

I checked, there were no wheels for 3.7, so this was a build from source. The pyproject.toml requirements say:

"numpy==1.17.3; python_version=='3.7' and (platform_machine!='arm64' or platform_system!='Darwin') and platform_machine!='aarch64' and platform_python_implementation != 'PyPy'",

So a pip install pywavelets should have built against numpy 1.17.3. At runtime, 1.19.5 must work then. The error message indicates that the wheel was somehow built against a newer numpy version than 1.19.5. Maybe you used python setup.py install in an environment with a newer numpy already installed?

I have the same issue. My python --version is Python 3.10.1 and numpy version is 1.24.2. I have tried to upgrade my numpy but it does not work. I need pywt to do my school project. I'd be grateful if this problem can be solved.

This error is guaranteed to go away if you install the latest numpy. There's nothing else that can be done here - a pip install numpy pywavelets will always work.
