dvc push: progress bar frozen at 0% when pushing to S3 until completed on M1 MacBook Pro

Bug Report

Description

The progress bar remained frozen at 0% until it had completed sending data to S3. I thought S3 was broken or so, but it was just the progress bar not working. This was not a short push but 100 MB and took a few minutes on my connection. The upload finished fine, however. (Took me a random break to not ctrl-c and see that it finished eventually.)

Reproduce

Setup a remote to S3 and add some data.

dvc push

Expected

A progress bar that keeps updating every 10 seconds or so.

Environment information

Output of dvc doctor:

PyCharm’s terminal. Note that it’s not a TQDM or similar issue. The overall progress bar works:

E.g.:
