error in downloading one of the datasets using Docker -- requests.exceptions.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

When I ran your Docker for downloading the datasets I got this error for one of the datasets. Have you tested your Docker on Ubuntu 18.04 and Python 3.8? Here's my machine specs. Please let me know if you have a suggestion or fix in your docker.

Matplotlib created a temporary config/cache directory at /tmp/matplotlib-1adwzlk_ because the default path (/.config/matplotlib) is not a writable directory; it is highly recommended to set the MPLCONFIGDIR environment variable to a writable directory, in particular to speed up the import of Matplotlib and to better support multiprocessing.

@monajalal thank you for surfacing this - we have replicated and are working on a fix!

[Jacobsolawetz]

@monajalal we have pushed additional protection too prevent this bug from stopping download - please make sure you rebuild your docker with the most recent roboflow python package.

@FrancescoSaverioZuppichini is rebuilding and repushing the one we are hosting on Docker Hub 🚀
