Fix FileNotFoundError in Interacting_with_CLIP.ipynb for newer scikit-image versions

[tonywjs]

Problem

The notebook fails with FileNotFoundError when running on Google Colab with recent versions of scikit-image (0.25.x+):

FileNotFoundError: [Errno 2] No such file or directory: '/root/.cache/scikit-image/0.25.2/data'

This occurs because newer versions of scikit-image use lazy loading for sample images, and the skimage.data_dir directory may not exist until images are explicitly loaded.

Solution

Replace the directory-based image loading approach with direct function calls from skimage.data module:

• Instead of iterating over os.listdir(skimage.data_dir), use the corresponding skimage.data functions directly
• For motorcycle_right, use skimage.data.stereo_motorcycle()[1] since it's provided as part of a stereo image pair

Changes

• Added get_motorcycle_right() helper function to retrieve the right motorcycle image from stereo_motorcycle()
• Created image_functions dictionary mapping image names to their loader functions
• Modified the image loading loop to call functions directly instead of reading from filesystem

Testing

Tested on Google Colab with:

• Python 3.12
• scikit-image 0.25.2
• PyTorch 2.9.0+cu126
