Because pytorch currently gets downgraded to 1.7.1 when we install torchdyn, this creates an issue with torchtext

For those who might face a similar problem, the solution is to add the following line

!pip install torchtext==0.8.1

Thanks for pointing this out: torchvision also requires 1.8.1 apparently. The issue appears linked to our torchsde dependency which clamps torch to <1.8.0. Pinging @lxuechen @patrick-kidger.

This is something I've been wanting to fix too.

@lxuechen, thoughts? I can see your comment on the matter here, but I can't duplicate the issue. Are you still able to repro it?

I can run pytest test_adjoint.py on my machine without issues, in particular using python=3.8.8, pytorch=1.8.0, and cudatoolkit=11.1.74, and the master version of torchsde. Full environment below.

Thanks for the heads-up. Will be working on checking this tonight.

[Zymrael]

Everything works as intended now, thanks!
