Couldn't find activation function mish, going with ReLU #6071

Couldn't find activation function mish, going with ReLU

I've been getting this error whenever I try to run the new YoloV4

yassinesefrioui commented 4 years ago

i have the some error

francismontalbo commented 4 years ago

It works with yolov4-tiny I managed to train my own dataset. It only uses LeakyReLU

However, I'm having problem with the 'mish' activation.

imaami commented 4 years ago

I have a patch for this in a branch but I haven't made a pull request, I'll try to do that today.

francismontalbo commented 4 years ago

Hoping for an update on this soon. Thank you, guys!

imaami commented 4 years ago

A quick heads-up: I didn't have enough oomph left last night after a hot day and household chores to make the pull request happen. I'll do it in a couple hours as soon as I get another cup of coffee going and the air conditioning set up...

Edit: Still didn't have time, bah...

francismontalbo commented 4 years ago

Hello, was this fixed? Is mish now working? Thank you!

francismontalbo commented 4 years ago

Still getting the same error

No, sorry, I haven't had time for it yet. I'll let you know ASAP.

francismontalbo commented 4 years ago

Thank you my friend. Be safe.

@francismontalbo You know what, I don't know why you're seeing that error. I thought one of my bugfix branches deals with what you described, but I misremembered. The current unmodified master branch should be able to parse "activation=mish" in cfg files just fine.

I ran YOLOv4 inference on my computer, both with GPU enabled and without it, and I don't see the error at all. And looking at the source code I don't see any reason why it shouldn't work, either. The function get_activation() in src/activations.c - the only place that prints the error message you're getting - has recognized the word "mish" since commit bf8ea4183 in November 2019.

So either you're accidentally running an old build, or there's a bug in the parsing code that I'm not hitting, or maybe you have some local changes in the cfg file.

Can you please triple-check everything and give details about where you got the binary, any possible local changes you have, etc.

Thank you my friend. Be safe.

You too, thank you for the kind words!

Thank you for the quick response my good friend. This helps me a lot. Btw is there a way for me to download an updated build of the darknet.exe? I previously used the one I found before, which works perfectly with yolov4-tiny but not with yolov4 due to the mish function. Would be helpful if I could find an updated build just like before. Thank you!

Sorry for bothering.

I'm building a bugfix branch right now, I assume you're on Windows? I'll post a download link as soon as I can.
