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

Here the update with minimum code:  
This works on my Windows PC but not on the Raspberry Pi.

```auto
from Networks import ImageNN_1
import torch

path="State_Dict_Camera1_ImageNN_1.pt"
net=ImageNN_1(3)
state_dict=torch.load(path)
print ("Worked")

```

I think the first problem is the version mismatch between your two machines (0.4.1 and 1.2.0a). Could you try installing 0.4.1 on the raspberry and checking again?

Thank you, downgrading did the Trick.
