reminisce commented on issue #8029: Bug on sum URL: https://github.com/apache/incubator-mxnet/issues/8029#issuecomment-332273223 For the script I posted above, using `MXNET_EXEC_INPLACE_GRAD_SUM_CAP=9` can run through. It might be caused by this block of code. https://github.com/apache/incubator-mxnet/blob/master/src/executor/graph_executor.cc#L192 There is a cycle in the gradient graph because `v[0] and v[1]` are the same node entry. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
