TensorFlow on JetPack 452 install issue

Hi Folks;
Just updated my Nano with JP 452. Attempting to install TensorFlow following instructions on NVidia site. Getting the following errors…

During handling of the above exception, another exception occurred:

Anyone know why this is hapening on a freshly instatlled system?

Thanks

Hi,

This is a network issue.

HTTPSConnectionPool(host=‘developer.download.nvidia.com’, port=443): Read timed out.

Could you share the command you used for installing the TensorFlow?
Is this one?

$ sudo pip3 install --pre --extra-index-url https://developer.download.nvidia.com/compute/redist/jp/v45 tensorflow

If yes, could you validate if the network works well from your Nano?
And could you also try to open the below link with Nano’s browser?
https://developer.download.nvidia.com/compute/redist/jp/v45

Thanks.

Yes it is command. I can go to that url. I can then go into the TensorFlow directory and see all of the whl packages. I can download them all without problem, except the first one. The first one I had to resume the down load several times to complete. I then went back to my terminal win. I reran the pip install command and now it appears that it is all moving along.

Thanks for your reply. I will let you know of any further hiccups.
