MXNetError: [20:00:12] D:\Program Files (x86)\Jenkins\workspace\mxnet\mxnet\src\imperative\imperative.cc:372: Check failed: !AGInfo::IsNone(*i) Cannot differentiate node because it is not in a computational graph. You need to set is_recording to true or use autograd.record() to save computational graphs for backward. If you want to differentiate the same graph twice, you need to pass retain_graph=True to backward.
I used slice operator in some calculations.
I just started using mxnet, and I’m not sure what the error is.Please help me.
