ValueError: Image size is zero in Google Colab

Question

I'm learning ML model training following this tutorial from Tensorflow. I have uploaded my own dataset from my computer to a folder named "sample_arrow" in Google Colab and specified the path to it:

image_path = 'sample_arrow'

The folder contains images, the size is not 0. But I get an error when executing this line of code:

data = DataLoader.from_folder(image_path) train_data, test_data = data.split(0.9)

ValueError: Image size is zero

What is wrong here? Maybe the folder path is not specified correctly? I'm completely new to the topic, unfamiliar with Pyhon (have Java skills) and would appreciate a detailed answer.

Answer 1

At last, I've found the solution. Import os and the correct path definition were missing:

import os


root_path = "/content/"    
image_path = os.path.join(os.path.dirname(root_path), 'sample_arrow')
