Colab can't find a file

Question

training_dataset_file = open('C:/Users/kbg04289/Desktop/mnist_train.csv', 'r')

I tried several methods like 'making address with \' and checking path.

Only google colab makes trouble, however jupyter notebook and visual studio code does well.

Answer 1

Colab doesn't have access to your local drive.

from google.colab import files
uploaded_files = files.upload()

This will prompt you to upload a file to Colab and you'll then be able to do the following once the upload is complete:

training_dataset_file = open(uploaded_files['<filename>'], 'r')
