After reference searching and discussion, we found this code can work with yolov3-tiny.cfg by a simple modification in yolomodel.py. This modification won't effect the process of yolov3.cfg.
Please refer to https://github.com/ultralytics/yolov3/issues/51 what the modification in model.py that glenn-jocher reported.
In here, we simply substitute line #284 in yolomodel.py ( in createmodules() ): pool = nn.MaxPool2d(stride=stride,kernel_size=kernel_size)_ as following codes _if kernel_size == 2 and stride == 1: module.add_module('_debugpadding%d' % index, nn.ZeroPad2d((0, 1, 0, 1))) pool = nn.MaxPool2d(kernel_size=kernel_size, stride=stride, padding=int((kernelsize - 1) // 2)) by referring to the glenn-jocher's method in model.py.
*ps: We also tried _pool = nn.MaxPool2d(stride=stride,kernel_size=kernel_size, ceilmode=True) Yet this didn't work.
If anyone has any better idea, please do make us know. Thanks a lot!
Hi @horngjason, when I try to run with yolov3-tiny, it has error:
Traceback (most recent call last):
File "sparsity_train.py", line 154, in
Did you encounter the same problem?

But I use this it reminds me out of memory,Before I use it I encounter RuntimeError: invalid argument 0: Sizes of tensors must match except in dimension 1.

Did you encounter the same problem?
So did you solve it?
Hi @talevolano,
For yolov3.cfg, it works. Yet I can make yolov3-tiny work with this code by simply change the cmd to point to yolov3.cfg as well as yolov3.weights. I would like to inquire whether or not this implementation can access yolov3-tiny.cfg with yolov3-tiny.weights? Thanks.
