Install Pytorch on Blender 2.90 python on Windows
Basically, it's not much different from installing on Blender 2.8x. I thought that it would not be possible to install it in 2.90, but it was easier than I expected. I don't have much information, but I'll make a note of it.
Premise
- Windows 10 Home/Pro
- Blender 2.90
Blender is assumed to be installed in C: \ Program Files \ Blender Foundation. It is assumed that the CUDA and GPU drivers are already installed.
procedure
- Open PowerShell ** with administrator privileges **.
- Upgrade pip.
- Install pytorch.
Only this.
.powershell
> cd C:\Program Files\Blender Foundation\Blender 2.90\2.90\python\bin
> ./python -m pip install --upgrade pip

To install Pytorch, just copy and paste the CUDA version etc. from the official page as usual.
In addition, use pip to add necessary items such as matplotlib.
.powershell
> ./python -m pip install matplotlib

Tested with Blender's python console
If it's installed successfully, you can run import torch in Blender's python console.
By the way, when I tried to run pytorch_example / mnist / main.py, I got an error saying that I don't have permission. For the time being, this can be avoided by running blender with administrator privileges. You can also work around this by installing blender in a folder that your users can access.
