In Gull tracking (see latest version in #167), anaconda-project run gives the following error:

@jlstevens note that this issue appears with versions of anaconda-project that display a progress bar when downloading data. With 0.8.3 it works fine, this is the version pinned in the README. When I installed anaconda-project in the first place I didn't follow that pin since it seemed a little outdated. So to deploy this notebook and until there's a new version of anaconda-project that fixes this bug, you may have to use one of the older versions without the progress bar.

[jlstevens]

Thanks for tracking that down.

The progress bar was added to anaconda-project at our request so I'll file a bug report there. It probably just needs to catch the case when it can't show the progress bar (for whatever reason) and continue as normal.

[maximlt]

I've already opened an issue and submitted a PR there, it's linked above.

[jlstevens]

Ah, I missed that. Thanks!

Can this issue be closed, or is the problem still persisting?

[maximlt]

I think the problem has been solved in anaconda-project. @Azaya89 can you search in the repository if we recommend somewhere installing an older version of anaconda-project. If so, please update the docs to pin the latest version.

Pls, what docs should I update? Is it the Contributing guide?

[maximlt]

It seems that there's one place where we recommend installing version 0.8.3. That should be updated.
