There is a CPU which has 10 CPU cores(20 CPU threads) on my Debian PC.
I installed fastai for CPU build.
When I run the sample code learn.fit_one_cycle(4) in lesson1-pets.ipynb to train the model,
I found my CPU usage is just about 20% rather than 100%. And only 4 CPU threads is fully running and other 16 CPU threads is idle.
Can someone know how to enable all my 20 CPU threads running ?
