Subject: Improve mismatched storage error message. (#19068)
X-Git-Tag: accepted/tizen/6.5/unified/20211028.231830~287
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d537e123105717c9af85df6446cffca5897ba65a;p=platform%2Fupstream%2Fpytorch.git

Improve mismatched storage error message. (#19068)

Summary:
Previously the error message would look like:
```
Attempted to set the storage of a tensor on device cuda:0 to a storage on different device cuda. This is no longer allowed; the devices must match.
```

Now it looks like:
```
Attempted to set the storage of a tensor on device "cuda:0" to a storage on different device "cuda". This is no longer allowed; the devices must match.
```
