Bug: TypeError: 'dict' object is not callable

[geneing]

There's a bug in this line TypeError: 'dict' object is not callable:

onnx2tf/onnx2tf/ops/SequenceEmpty.py

Line 33 in 2bff6c8

sequence_dtype = ONNX_DTYPES_TO_TF_DTYPES(graph_node.attrs.get('dtype', 1)) # Float32

However, ONNX_DTYPES_TO_TF_DTYPES is a dict. Probably just changing brackets to [] would fix it.
