when i was running code as follow:

```
cam_coords = pixel2cam(depth.squeeze(1), intrinsics.inverse())
```

The second parameter of `pixel2cam(depth.squeeze(1), intrinsics.inverse())`

contains nan,

then i added this code before it:

```
if torch.any(torch.isnan(intrinsics.inverse())):
print(intrinsics)
print(intrinsics.inverse())
print(torch.isnan(intrinsics.inverse()))
print(torch.any(torch.isnan(intrinsics.inverse())))
```

and got output as follow:

This result seems contradictory. After it enter the

`if torch.any(torch.isnan(intrinsics.inverse())):`

why does ` print(torch.any(torch.isnan(intrinsics.inverse())))`

output False. In addition, the output of `print(intrinsics.inverse())`

does not contain nan.How does this happen?
