I’m trying to run a pytorch script which is using torchaudio on a google TPU. To do this I’m using pytorch xla following this notebook 1, more specifically I’m using this code cell to load the xla:
!pip install torchaudio
import os
assert os.environ['COLAB_TPU_ADDR'], 'Make sure to select TPU from Edit > Notebook settings > Hardware accelerator'

VERSION = "20200220"  #@param ["20200220","nightly", "xrt==1.15.0"]
!curl https://raw.githubusercontent.com/pytorch/xla/master/contrib/scripts/env-setup.py -o pytorch-xla-env-setup.py
!python pytorch-xla-env-setup.py --version $VERSION

import torch

import torchaudio

import torch_xla

however this is incompatible with the version of torchaudio that I need as: ERROR: torchaudio 0.4.0 has requirement torch==1.4.0, but you'll have torch 1.5.0a0+e95282a which is incompatible.
I couldn’t find anywhere how to load torch 1.4.0 using pytorch xla.
I tried to use the nightly version of torch audio but that gives the error as follows:
!pip install torchaudio_nightly -f https://download.pytorch.org/whl/nightly/torch_nightly.html

import os
assert os.environ['COLAB_TPU_ADDR'], 'Make sure to select TPU from Edit > Notebook settings > Hardware accelerator'

VERSION = "20200220"  #@param ["20200220","nightly", "xrt==1.15.0"]
!curl https://raw.githubusercontent.com/pytorch/xla/master/contrib/scripts/env-setup.py -o pytorch-xla-env-setup.py
!python pytorch-xla-env-setup.py --version $VERSION

import torch
import torchaudio

import torch_xla

So how would I go to load the stable version or 1.4.0 version of pytorch using xla or is there any other workaround for this situation?
Thanks a lot for your help!
