Hello,
I’m trying to load a State Dict that I saved on a Windows PC with a Raspberry Pi. I’m getting an error message that delivers almost no results on google:
ValueError: whence value 1460 unsupported (full traceback below)
Here some info about the two systems:
-Windows machine:
-Windows 7, 64bit
-torch._ version _ prints “0.4.1”
-only training on cpu
-num_workers=0 when creating the DataLoader Class.
-Raspberry Pi:
-Raspberry Pi 3 Model b+
-torch._ version _ prints “1.2.0a0+7c40576”
-The file containing the network structure is the same
-I’m loading the state_dict with “self.net.load_state_dict(torch.load(path))”
-When I’m not trying to load the state_dict, everything works out fine (basicly only the forward pass of the model), but I obviously get the wrong values.
If needed, I will try to reproduce the issue with the minimal amount of code, but I thought I give it a try here first. Maybe I can solve the issue with additional parameters (like telling the model that it now runs on another processor)?
Thanks in advance an best regards,
Leo
