one major issue that I'm being experiencing randomly is this
it almost appear every time I try to export an engine
sometimes when this happens the process completely holds other times it continues I managed to get one successfully completed and use it to run sd with trt and I can say that it is significantly faster
but most of the time my engine fails to export, making this almost unusable

the engines does seem to be generated (saved to disk) but the profiles are just not created so webui doesn't see it

Cause and patch fix

as far that I can see this is caused by yield logging_history
I've made an edit to replace all yield logging_history with print(logging_history) and it seems to work fine

Having this issue as well, not able to complete the build due to h11 connection errors

As yield seems to be causing issues for some users it will be replaced by print and gr.Info. The changes are live on the hot_fix branch right now.
Currently, I don't have an ETA when this branch will be merged into the master but hopefully by end of this week latest.

[contentis]

hot_fix has been merged. I'll close the issue, but feel free to reopen if you still face issues.
