RuntimeError during get_model

[kelvinAI]

I'm facing a runtime error when loading the model, with the following parameters:

model = get_model("resnet50_2020-07-20", max_size=2048)
model.eval()

RuntimeError: version_ <= kMaxSupportedFileFormatVersion INTERNAL ASSERT FAILED at ../caffe2/serialize/inline_container.cc:132, please report a bug to PyTorch. Attempted to read a PyTorch file with version 3, but the maximum supported version for reading is 2. Your PyTorch installation may be too old.

I've tried upgrading torch and torchvision with !pip install --upgrade torch torchvision , as recommended by pytorch/vision#1943 but it wasn't resolved.

Current installed versions:

torch - 1.5.0a0+8f84ded
torchvision - 0.6.0a0 

Any recommendations?

How about try PyTorch 1.4 and torchvision 0.5.0? seems to work in similar problem but I'm not perfectly sure yet, and maybe there is more good version to safe.
!pip install torch=1.4 (torch vision also) and restart your colab or J.notebook
