Watson Studio MNIST教程中无法查看对象存储桶内文件

I ran into a similar problem when working through this exact tutorial—here are some practical fixes you can try to get those files showing up in the Image Data editor:

• Verify file format and structure: The Image Data component in Watson Studio requires image files in supported formats like PNG or JPG. Double-check that your files are in the right format, and make sure they’re stored directly in the root of the chmnist-1 bucket (not nested inside subfolders). Nested directories often prevent the component from detecting files.
• Refresh the page and reload the project: UI caching can cause this kind of glitch. Close the Watson Studio tab entirely, log back into your account, reopen the project, and navigate back to the Image Data setup dialog. This often clears the cached state and loads the files correctly.
• Confirm bucket permissions: Even if you can see the bucket, ensure your Watson Studio project has read access to it. Go to your project’s "Data" panel, locate the chmnist-1 bucket, and check the permission settings to confirm your project role has the necessary read permissions.
• Re-upload the files: If the above steps don’t work, download the files from the bucket to your local machine, delete the existing files in chmnist-1, then re-upload them directly (avoid uploading folders). Make sure the upload completes without any errors.
• Check file names: Avoid special characters, spaces, or non-English characters in your file names. Watson Studio can have trouble parsing these, so stick to simple names using letters, numbers, and underscores.
