With the 0.7 pytorch and old course my gpu utilization was 100% at times. After upgrading to pytorch 1.0 and course v3, the gpu usage was only spikes.
Pytorch v1.0 stable is now working on Windows but fastai v1 needs some tweaks to get it work on Windows
@sgugger might also want to fix this for a future version of the notebooks by adding
fn_paths = [item.as_posix() for item in fn_paths]
into the https://github.com/fastai/course-v3/tree/master/nbs/dl1 notebooks that operate on file names. This would make Jeremy’s regexp work on Win and Posix without us poor Windows users having to figure out REs on themselves
as_posix is in the library now, it has been suggested as a bug fix and will be in v1.0.43 when it’s released.
Trying to run lesson 1 on windows
set path = r’\([^\]+)_\d+.jpg$’ will fix it.But in the meet a issue—‘PicklingError’ until now, i can’t fix it.
