At some point after removing
theano.sandbox.cuda, Theano opted to raise anose.SkipTestexception instead of anImportErrorwhen trying to import it. Some checks in Lasagne were still expecting anImportErrorwhentheano.sandbox.cudawas not available. To avoid introducing a dependency onnose, this PR changes those checks to catch a genericException. This might mask other exceptions for users of Theano 0.8/0.9 trying to get CUDA to run, but avoids misleading exceptions for users of Theano 0.10. Seems that's the best we can do (without introducing a dependency onnoseor checking the exception class name).
