Suppress output in python?

[Dmitry Ulyanov]

Hello, I use python wrapper and I don't want to see any of caffe info it always prints about setup and so on. But whatever I do to suppress the output does not work for me, I tried many of standard python moves to switch stdout to something like 

sys.stdout = os.devnull

and then restore it, but it does not work, any ideas? Thanks!

Did you try stderr rather than stdout? I know at least some of the output goes to stderr.

[Dmitry Ulyanov]

Yes, I tried both

you can also try this:

python /your/script 2> /dev/null

when i run my python wrapper all the set up is piped through stderr so i just use the command above

Best Regards,

Thank you for the comment. This way works, but my workflow is like that: I run a server which should process incoming queries, so I  do 

net = caffe.Net(train_test, snapshot_path)

and that is the only time I want to suppress everything, but then I have some logs, that I want to see, so I tried methods to redirect output inside the script but got no luck

I found a workaround. See the code here:

It would be kinda nice if caffe turned off the output when using python by default.
