HOW TO INSTALL PYTORCH IN YOUR RASPBERRY PI 4

Follow the following steps

sudo apt-get upgrade python
pip3 install pyserial

Check your ARM architechture using the below command.

uname -a 

You must find that your using aarch64 if your running it on a Raspberry Pi 4.

Next find if your using bullseye version or the buster version of Rasbian using following.

cat /etc/os-release

Next, download the wheel files for torch library and for your torchvision library using the following links.

FOR TORCH 1.13.0

#buster

FOR TORCHVISION 0.14.0

#buster 
https://drive.google.com/uc?id=1m6wEbl_jJGaQL-vg4zkNfc9TNwl2_J4o

Next install the dependencies.

sudo apt install libopenblas-dev libblas-dev m4 cmake Cython python3-dev python3-yaml python3-setuptools python3-wheel python3-pillow python3-numpy

Now Copy the downloaded wheel files from PI->downloads to your working directory.

Example: the files for bullseye version after download are:

torch-1.13.0a0+git7c98e70-cp39-cp39-linux_aarch64.whl

torchvision-0.14.0a0+5ce4506-cp39-cp39-linux_aarch64.whl

Install torch using the wheel file as follows:

sudo -H pip3 install torch-1.13.0a0+git7c98e70-cp39-cp39-linux_aarch64.whl

Install torchvision using the wheel file as follows:

sudo -H pip3 install torchvision-0.14.0a0+5ce4506-cp39-cp39-linux_aarch64.whl

Testing:

python3

    >> import torch
    >> import torchvision 
    >> (cntr + z to exit)

If your imports run without any errors then your libraries have been installed correctly. You can start using them in your codes..
