So, I am not able to install it either. I installed PyTorch and torchvision using the instructions here.
They are for sure installed:
>>> import torch
>>> torch.__version__
'1.4.0'
>>> import torchvision
>>> torchvision.__version__
'0.5.0a0+85b8fbf'
But installing retinanet-examples does not work. I built a wheel, but it won’t install.
$ pip3 install odtk-0.2.0-cp36-cp36m-linux_aarch64.whl

If I try to install it globally, since torchvision won’t do a --user install on tegra, i get this:
Running setup.py install for pbkdf2 ... done

Nvidia documentation seems to state that int8 calibration should be performed on the same device that the network is run on but in the case of Xavier I am not able to get it working and unfortunately I have no card for x86 that supports fast int8 (edit: apparently I do. supported by 1080). Apart from some example code that does similar things, I can find no int8 calibration tool.
My understanding is I need to do two things:
- convert my .pth to an onnx
- make a calibrated .plan with the supplied dataset
Unfortunately I am stuck, however, without a .pth to .onnx conversion. If it’s not possible to install retinanet-examples on xavier, is there an alternative conversion utility lying around in a repo somewhere?
