In numpy mode everything works fine.
NDArray mode throws:
```
File "leaky.py", line 5, in <module>
b = mx.ndarray.LeakyReLU(input)
File "<string>", line 72, in LeakyReLU
File
"/home/wihajster/Desktop/incubator-mxnet/python/mxnet/_ctypes/ndarray.py", line
82, in _imperative_invoke
check_call(_LIB.MXImperativeInvokeEx(
File "/home/wihajster/Desktop/incubator-mxnet/python/mxnet/base.py", line
246, in check_call
raise get_last_ffi_error()
mxnet.base.MXNetError: Traceback (most recent call last):
File "../src/imperative/imperative.cc", line 678
MXNetError: Check failed: shape_is_known(arr.shape()):
```
I think this is correct behavior, as legacy mode doesn’t let empty arrays.
