Torch module install failed

I just installed this wonderful app and I was wondering whether the pytorch is available on it or not yet. After I typed ‘%pip install torch’ ,it showed this error report.Is that means torch is not available. Or am I just need to set something right before running the install process.
Thanks!

No source file or test is named. Start by reproducing `%pip install torch` in Carnets and inspect the reported torch `setup.py` failure, especially `ModuleNotFoundError: No module named 'tools.nnwrap'`. Done means establishing whether PyTorch is supported in this app and identifying a confirmed fix or documented limitation.
