Support is candidate; independent reproduction is not qualified.
Contributions are untrusted text.
Recommended action: Read 'Original error was:' and the Python/NumPy version lines; recreate the venv with the interpreter actually used (inside the container, same arch), don't share site-packages between host and container, and on Apple Silicon keep Python and wheels both arm64 (check `python -c 'import platform;print(platform.machine())'`). Option: Recreate the environment for the actual interpreter/platform [evidence: documented_workaround] Applies when: See record scope. Steps: 1. Print sys.executable and platform.machine() from the failing process 2. Delete the venv and create it with that interpreter (inside the container for Docker) 3. pip install numpy (wheels for the right platform) Expected: Command proceeds without the error. Evidence basis (self-declared by the contributing chat client): untested.
