UserWarning: Default upsampling behavior when mode=bilinear is changed to align_corners=False since 0.4.0. Please specify align_corners=True if the old behavior is desired. See the documentation of nn.Upsample for details.

This error occurs when I run demo.py. Is this a problem with pytorch? However, the environment is executed according to the configuration file. thank you

I meet same problems,can you solve it ?@fengzifrank

This is a warning from PyTorch as there is a change in the behavior of upsampling since version 0.4.0. You can safely ignore this warning.

The problem of changing his model is solved. CornerNet_Saccade() seems to have some problems.

#!/usr/bin/env python
import cv2
from core.detectors import CornerNet_Squeeze
from core.vis_utils import draw_bboxes

detector = CornerNet_Squeeze()
image = cv2.imread("demo.jpg")

bboxes = detector(image)
image = draw_bboxes(image, bboxes)
cv2.imwrite("demo_1.jpg", image)

In pytorch official tutorial, there are some clear explanation about this problem. https://pytorch.org/docs/stable/nn.html?highlight=upsample#torch.nn.Upsample
that is:
With align_corners = True, the linearly interpolating modes (linear, bilinear, bicubic, and trilinear) don’t proportionally align the output and input pixels, and thus the output values can depend on the input size. This was the default behavior for these modes up to version 0.3.1. Since then, the default behavior is align_corners = False. See below for concrete examples on how this affects the outputs.

seems it is related with pytorch jit: DeepVAC/TorchPod#47

I solved problem.
the problem is opencv version base on c++, so that is Segmentation fault
just typed the commandline to change version of opencv:
$ pip3 install opencv-python==4.0.1.24
