warnings cannot be accessed in notebooks

[yueyinqiu]

For example, the following codes can produce a warning in the console

using TorchSharp;

var loss = torch.nn.MSELoss();
var x = torch.zeros([]);
var y = torch.zeros([1]);
loss.call(x, y);

However this seems to be unable to access on other platforms, like polyglot notebooks.

Right. The warning is coming from libtorch, and going to stderr. I don't know if there's a way to redirect errors to the Notebook console, but that would be the general solution.
