Can this code runs yolov3-tiny?

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.

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 create_modules() ):
pool = nn.MaxPool2d(stride=stride,kernel_size=kernel_size)
as following codes
if kernel_size == 2 and stride == 1:
module.add_module('debug_padding%d' % index, nn.ZeroPad2d((0, 1, 0, 1)))
pool = nn.MaxPool2d(kernel_size=kernel_size, stride=stride, padding=int((kernel_size - 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, ceil_mode=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:

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.

So did you solve it?
