Detailed Description

A helper class to indicate that the operator should have no gradient.

This is used when the operator definition is designed to not have a gradient. Calling a gradient on this operator def will cause Caffe2 to quit.

Member Function Documentation

Get()

GradientOpsMeta caffe2::ThrowInTheTowelIfGradientIsCalled::Get ( )

inlineoverridevirtual

Returns the gradient ops meta.

If your gradient op generator only use standard input and output manipulations, you can simply implement GetGradientDefs() that returns vector<OperatorDef>. In that, you can call GI, GI_V and GI_I that will automatically create the gradient registration for you.

If you need to do custom gradient name registration, overload this function directly.

Reimplemented from caffe2::GradientMakerBase.
