@dusty_nv, I performed the task mentionedabove, check my sequnce of commands:
wget https://nvidia.box.com/shared/static/wa34qwrwtk9njtyarwt5nvo6imenfy26.whl -O torch-1.7.0-cp36-cp36m-linux_aarch64.whl
sudo apt-get install python3-pip libopenblas-base libopenmpi-dev
pip3 install Cython
sudo apt-get install libavcodec-dev
sudo apt-get update
sudo apt-get upgrade
cd Documents/installer/
pip3 install numpy torch-1.7.0-cp36-cp36m-linux_aarch64.whl
sudo apt-get install libjpeg-dev zlib1g-dev libpython3-dev libavcodec-dev
git clone --branch v0.8.1 https://github.com/pytorch/vision torchvision
export BUILD_VERSION=0.8.0
cd torchvision/
sudo python3 setup.py install
And the final output after trying to install torchvision is (error output):
from /home/nano/Documents/installer/torchvision/torchvision/csrc/cpu/video_reader/VideoReader.cpp:6:
/home/nano/Documents/installer/torchvision/torchvision/csrc/cpu/decoder/defs.h:13:10: fatal error: libavformat/avformat.h: No such file or directory

I’ve not specifically installed “ffmpeg”. “ffmpeg -version” gives the following output:
