Using a-shell on iPad Pro 4. Failed to pip install scipy. I am not sure what’s the problem. I tried to install/upgrade meson-python and pyproject.toml, but it seems that the package is already up to date. A-shell comes with pandas and numpy pre installed. I tried to upgrade numpy and I got the same error message. Finally, I tried to install older versions of scipy and it keeps failing for similar reasons.
