Hi,
I am trying to install pytorch v1 on TX2 with Jetpack 3.3 and I m getting the following error after running the command $ python setup.py install:
....
subprocess.CalledProcessError: Command '['cmake', '--build', '.', '--target', 'install', '--config', 'Release', '--', '-j', '6']' returned non-zero exit status 2
I also tried to run python setup.py build_deps but I am getting error: invalid command 'build_deps'

Do you know how could I solve it?

Thanks a lot!

I found the following comment in setup.py and it solved my issue (i had the same)

It is no longer necessary to use the 'build' or 'rebuild' targets

To install:
  $ python setup.py install
To develop locally:
  $ python setup.py develop
To force cmake to re-generate native build files (off by default):
  $ python setup.py develop --cmake

See the build instructions from this post for PyTorch v1 -- https://devtalk.nvidia.com/default/topic/1049071/jetson-nano/pytorch-for-jetson-nano-version-1-3-0-now-available/ Note that it disables NCCL through and environment variable before you run setup.py

Hey @dusty-nv , it seems that the latest release of NCCL 2.6.4.1 recognizes ARM CPUs. I'm currently attempting to install it to my Jetson TX2, because I have been wanting this for some time. However, I must warn: some scripts from the master branch of nccl git are commited with messages from previous releases, which is a yellow flag. If I do get it, I intend to release all my configuration and installation scripts for the community. I'll let you know.

Have a good one.

git submodule update --init --recursive

Hi Everyone, I am having a similar issue and need some assistance. I am trying to install pytorch on the odroid board xu4 but I get the following error: incompatible types when assigning to type ‘int32x4_t’ from type ‘int’. Below is the error message directly from the terminal.
