C2_W2 CORS policy: No 'Access-Control-Allow-Origin

I want to complete the assignment but I found this error:

Access to fetch at ‘https://storage.googleapis.com/learnjs-data/model-builder/fashion_mnist_labels_uint8’ from origin ‘’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. If an opaque response serves your needs, set the request’s mode to ‘no-cors’ to fetch the resource with CORS disabled.

I think my browser can’t download the dataset

Hey @MohammadReza_Lahmi,

Try to follow the instructions here

Check your browser setting especially if it is blocking any other tools, website origin.

Another issue like this can happen if you have not saved or download this file in your local drive as it looks for files at this place always.
