cudnn-license gjs lambda-stack-cuda libcub-dev libcupti-dev libcurand10 libcusolver11 libcusolvermg11 libgjs0g libnvidia-ml-dev libnvtoolsext1 libnvvm4…

BTW I’m using both PyTorch and Tensorflow for from-scratch training as well as transfer learning on Ubuntu 22.04 LTS.

From a performance viewpoint I’m happy with the Tensorbook. Good enough to train smaller models. Build quality so-so, the screen fell out one day, but Duck tape always works.

I.e. I ran
```bash
wget -nv -O- https://lambdalabs.com/install-lambda-stack.sh | sh -
sudo reboot
```
After reboot python3 wasn’t able to import tensorflow or torch. So …
