I am using tqdm 4.23 on Py3.5 on Ubuntu 16.04.

In the code example attached here I am trying to reproduce the same execution in a sequential process and in a multitasking. I am using the logging with the write channel redirect through tqdm writer.

While in the sequential I reach my goal:

Test 0
Test 1
Test 2
...

In the multithread I am getting twice the output (or errors when I modify the code):

My thread 5
My thread 5
My thread 6
My thread 6
....

Some could give me some tip?
