Snowflake Documentation is available at:

Release Notes - v4.4.0(March 24,2026) - Bump the lower boundary of cryptography to 46.0.5 due to CVE-2026-26007. - Added support for Python 3.14. - Removed pyOpenSSL upper bound dependency constraint to allow installation of pyOpenSSL 26.0.0+, which includes a fix for GHSA-vp96-hxj8-p424. - Fixed Azure IMDS header to use lowercase instead of , which caused 400 errors during Azure Workload Identity Federation authentication. - Fixed default to be 20MB instead of 200MB, as the previous value was set too high and could cause out-of-memory issues. - Fixed a bug where Azure GET commands would incorrectly set the file status to UPLOADED instead of preserving the DOWNLOADED status during metadata retrieval. - Renamed the environment variable for skipping config file permission warnings from to . The old variable is still supported but emits a deprecation warning. - Fixed flag not being respected when reading . - Fixed JSONDecodeError in resultbatch.load() when fetching large result sets

Installation Errors

Common errors when installing snowflake-connector-python with pip.

ModuleNotFoundError: No module named 'snowflake_connector_python'

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

Fix: Run pip install snowflake-connector-python. If using a virtual environment, ensure it is activated first.

ModuleNotFoundError: No module named 'snowflake_connector_python' (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 snowflake-connector-python to install into the interpreter you are running.

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

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

Fix: Check the version with pip show snowflake-connector-python and upgrade with pip install --upgrade snowflake-connector-python.

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 snowflake-connector-python. 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 snowflake-connector-python

SSL: CERTIFICATE_VERIFY_FAILED

Fix: Try: pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org snowflake-connector-python

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.
