# RuntimeError: No CUDA GPUs are available and ValueError > Source: > Published: 2026-09-07 10:45:38+00:00 Hello everyone, this is my first post on this forum. I made a pottery dating machine. The space is called ‘terraID’. However, whenever I click the ‘Analyze’ button, I keep getting the error that there are No CUDA GPUs are available. I tried everything(yes, import Spaces is the first line of the app.py). Is there anyone who knows how this problem can be solved?There is also a ValueError that I can’t quite figure out. My username is ‘Stormpie’. Thanks in advance for the help! ===== Application Startup at 2026-09-07 08:25:26 ===== # [notice] To update, run: pip install --upgrade pip # # Device at startup: CPU CLIP: lazy-loaded on ZeroGPU request Imported 490 memory examples from museum_memory.json FAISS memory rebuilt: 490 vectors Could not load classifier: PytorchStreamReader failed reading zip archive: unsupported multidisk archive. This is an internal miniz error. If you are seeing this error, there is a high likelihood that your checkpoint file is corrupted. This can happen if the checkpoint was not saved properly, was transferred incorrectly, or the file was modified after saving.
