a MUST-read to confirm that both GPU and drivers support the CUDA version you've installed (or about to install):

Tacotron2 script was not seeing my cuda. I have a GPU RTX 2070 and CUDA toolkit 11.7.
Checks:
>> nvcc -V (to get detail re nvcc: NVIDIA (R) Cuda compiler driver)
>> nvidia-smi (to obtain GPU info)
>> conda list cudatoolkit (to see package info confirming installation)
>> python -c "import torch; print(torch.cuda.is_available())" (it printed False for me, which means PyTorch was not compiled with CUDA support,
                                                               so I had to reinstall it with the cuda flag following the steps from the next assertion error described below.)
In the end, it 'Successfully installed  +cu117'.
Note that on Windows you must also specify 'gloo' backend in hparams.py as Windows doesn't support nccl distributed computing as of the time of writing.
