Cannot install environment-dev.yml on CPU

Describe the bug Cannot develop on MacOS Big Sur (11.5.2) on CPU.

To Reproduce Steps to reproduce the behavior:

Run conda env create -f environment-dev.yml
Error output:
```
Solving environment: failed
```

ResolvePackageNotFound:

pytorch==1.9.0=py3.8_cuda11.1_cudnn8.0.5_0
cudatoolkit=11.1
pytorch3d

Expected behavior Expected installation of pytorch, cudatoolkit, pytorch3d

Screenshots If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

OS: Big Sur: (11.5.2)
Python Version: (
Graphein Version [e.g. 22] & how it was installed

Additional context Installation works with the normal environment.yml file. I tried independently installing through pytorch.org with the command conda install pytorch torchvision torchaudio -c pytorch, but after running the example code:

from graphein.protein.config import ProteinGraphConfig
from graphein.protein.graphs import construct_graph

config = ProteinGraphConfig()
g = construct_graph(config=config, pdb_code="3eiy")

Error output:
