How to install CUDA in Google Colab GPU's

Question

It seems that Google Colab GPU\'s doesn\'t come with CUDA Toolkit, how can I install CUDA in Google Colab GPU\'s. I am getting this error in installing mxnet in Google Cola

Answer 1

Cuda is not showing on your notebook because you have not enabled GPU in Colab.

The Google Colab comes with both options GPU or without GPU. You can enable or disable GPU in runtime settings

Go to Menu > Runtime > Change runtime.

Change hardware acceleration to GPU.

To check if GPU is running or not, run following command

!nvidia-smi

If output is like following image it means your GPU and cuda is working. You can see cuda version also.

After that to check if PyTorch is capable of using GPU, run the following code.

import torch
torch.cuda.is_available()
# Output would be True if Pytorch is using GPU otherwise it would be False.

To check if TensorFlow is capable of using GPU, run the following code.

import tensorflow as tf
tf.test.gpu_device_name()
# Standard output is '/device:GPU:0'
