Download

A no-frills tool to download files from the web. It will attempt to be smart about not downloading data that's already there, checking to make sure that there were no errors in fetching data, automatically unzipping the contents of downloaded zipfiles (if desired), and displaying a progress bar with statistics.

.. note::

This draws heavily from the
`MNE-python <https://martinos.org/mne>`_ ``_fetch_file`` function.

This package doesn't get a ton of developer attention, but is hopefully well-scoped enough that it should still be useful! If you'd like to help improve it, fix bugs, etc, please reach out in the issues!

Frequently Asked Questions

.. _faq/file-size:

Why do I occasionally get a "Error file size is..." error? ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Occasionally, when you try to download a file, the server from which you are downloading will return that the download is finished, when it is not. download will check whether the final downloaded file is the correct size. If not, it will throw this error. In this case, you should try re-downloading the file.
