optima2005 commented on issue #4659: [CONV3D] remove incorrect schedule for conv3d_ndhwc URL: https://github.com/apache/incubator-tvm/pull/4659#issuecomment-572833998 @masahi Yes. it would report error. Currently at least in TF frontend, the NHWC for conv2d, NDHWC for conv3d are forced to transform to NCHW/NCDHW layout. Please see [this](https://github.com/apache/incubator-tvm/blob/d6a23cf50fc5b9ddccfac679927f04b3baa1fe97/python/tvm/relay/frontend/tensorflow.py#L2291), [this](https://github.com/apache/incubator-tvm/blob/d6a23cf50fc5b9ddccfac679927f04b3baa1fe97/python/tvm/relay/frontend/tensorflow.py#L298) and [this](https://github.com/apache/incubator-tvm/blob/d6a23cf50fc5b9ddccfac679927f04b3baa1fe97/python/tvm/relay/frontend/tensorflow.py#L430). I guess that might be under perormance consideration. But a more user friendly approach may be needed to notice the user TVM not supporting those layouts under cuda target.
