Hi @yuanjinghui,
We recently (3.8 or 3.9, I don’t remember) switched to fastprogress.
The problem is probably more related to fastprogress than to PyMC3, so please try the following:
- make sure you have installed a recent/latest version of
fastprogress - try to use just
fastprogresswithout PyMC3 in Pycharm (e.g. their Example 1)
If the problem persists, it will be interesting to see if the progress bar is only missing when created through PyMC3, or also if it’s just the standalone example.
