[GitHub] [incubator-mxnet] matteosal opened a new issue #16143: Failure of
MKL-DNN Convolution from C API
matteosal opened a new issue #16143: Failure of MKL-DNN Convolution from C API
URL: https://github.com/apache/incubator-mxnet/issues/16143
## Description
With MKL-DNN, getting the output of a Convolution operator using the C API can trigger this error:
```
[14:52:08] src/ndarray/ndarray.cc:757: Check failed: !IsMKLDNNData(): We can't generate TBlob for MKLDNN data. Please use Reorder2Default() to generate a new NDArray first
```

mx_uint b_shape[1] = {40};
NDArrayHandle b_arg_arr;
MXNDArrayCreateEx(b_shape, 1, dev_type, dev_id, 0, 0, &b_arg_arr);
/* Create and bind executor */
ExecutorHandle ex;
NDArrayHandle arg[3] = {in_arg_arr, w_arg_arr, b_arg_arr};
NDArrayHandle grad[3] = {NULL, NULL, NULL};
NDArrayHandle *aux = NULL;
mx_uint req[3] = {1, 1, 1};
MXExecutorBind(sym, dev_type, dev_id, 3, arg, grad, req, 0, aux, &ex);
/* Get executor output handle */
mx_uint out_size;
NDArrayHandle *out_arr_p;
MXExecutorOutputs(ex, &out_size, &out_arr_p);

MXExecutorForward(ex, 0);
/* Read output */
MXNDArrayWaitToRead(out_arr);
void *data;
if(MXNDArrayGetData(out_arr, &data) != 0)
printf("%s\n", MXGetLastError());
else
printf("Ok!\n");
return 0;
}
```
## Steps to reproduce
Running the above standalone C program triggers the mentioned error. The error is not triggered if the output has less than 40 channels, or the if the line `MXNDArrayWaitToRead(out_arr);` is commented out.
I haven't been able of reproducing this error with the Python interface.
