Installation Errors

Common errors when installing statsmodels with pip.

ModuleNotFoundError: No module named 'statsmodels'

Cause: The package is not installed in the current Python environment.

Fix: Run pip install statsmodels. If using a virtual environment, ensure it is activated first.

ModuleNotFoundError: No module named 'statsmodels' (installed but still failing)

Cause: pip installed the package into a different Python than the one running your script.

Fix: Use python -m pip install statsmodels to install into the interpreter you are running.

ImportError: cannot import name 'X' from 'statsmodels'

Cause: The function or class does not exist in the installed version.

Fix: Check the version with pip show statsmodels and upgrade with pip install --upgrade statsmodels.

pip: command not found

Cause: pip is not in PATH or Python was not added to PATH during installation.

Fix: Try python -m pip install statsmodels. On macOS/Linux try pip3.

PermissionError: [Errno 13] Permission denied

Cause: No write access to the system Python package directory.

Fix: Use a virtual environment, or add --user: pip install --user statsmodels

SSL: CERTIFICATE_VERIFY_FAILED

Cause: pip cannot verify PyPI's SSL certificate — common behind corporate proxies.

Fix: Try: pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org statsmodels

MemoryError when loading data

Cause: Dataset is too large to fit in RAM.

Fix: Read in chunks, filter columns on load, or consider Polars/Dask for out-of-core processing.
