how to removed the Slice operation and replaced the input with a downscaled image and stacked it to match the channel number?
Hi,
Thanks for you work
i using my own trained model file will report error Slice operation in .pt or in .onnx?
more details needed as you
ONNX converts the operation of line 87 in common.py
return self.conv(torch.cat([x[..., ::2, ::2], x[..., 1::2, ::2], x[..., ::2, 1::2], x[..., 1::2, 1::2]], 1))
into a slice operation with steps.
The easiest way to eliminate the slice operation is to change this line into:
return self.conv(torch.cat([x,x,x,x], 1))
It is also possible to change this operation into a convolution operation.

Hi, Can I remove slice operation for trained model? I have trained my custom dataset, and converted it to pytorchscript. But the result is afwul (all boxes are wrong). Can I use models/onnx_export.py from ultralytics for my model and remove slice operation without retraining? Thank you so much
Of course, you can remove the slice operation without retraining.
