### 3D Model Generation File Access Error
- Problem: When attempting to generate the 3D model, an error occurred: "[Errno 2] No such file or directory: '/tmp/tmppgls861k.png'"
- This suggests that the temporary file created during the depth map generation is not accessible or has been deleted before the 3D model generation process.
- Next steps: Investigate the file handling in the `create_3d_model` function and ensure temporary files are properly managed and accessible.

### CUDA Initialization Error Fix
- Problem: CUDA was being initialized in the main process, causing an error in the Spaces Stateless GPU environment.
- Changes made:
  1. Modified `np.savetxt` to ensure depth is converted to a CPU numpy array if it's a torch.Tensor.
  2. Explicitly converted `focallength_px` to a float.
  3. Added more print statements throughout the `predict_depth` function for improved logging and debugging.
  4. Added a print statement just before returning from the `predict_depth` function to log all return values.
- These changes aim to prevent CUDA initialization in the main process and provide more detailed logging for troubleshooting.
