Error building torchvision from source. CalledProcessError: Command '['ninja', '-v']' returned non-zero exit status 1.

Hi, dear support team. I've faced the issue during installation process of torchvision from source on my Jetson Nano.
I followed instructions from official Nvidia site and succeeded in installation Torch v1.7.0. I build it from source cause i have python3.8.

The log file with the error could be found here

Here is the output of your environment data collection script:

Please, share the know!

Start by reading the linked build log and the official NVIDIA installation instructions referenced in the report, then compare them with the supplied PyTorch, Python, CMake, GCC, CUDA, and Jetson Nano environment details. Reproduce the torchvision source build if possible; done means identifying the cause of the ninja failure and confirming a successful build on the reported setup.
