Hello. I noticed a couple of problems while compiling an example with the tensorflow frontend module. The two small changes in the attached commit seem to fix the issues. One change is a simple rename of a dummy variable which was clashing with the function argument 'shape'. The second is to deal with the case of when a shrink axis operator produces a tensor with dimension zero - this does not seem to work with nnvm where the dimension must be at least one. I'd welcome any comments - particularly on whether this is the correct way to deal with the 0-dim result. Thanks.

pass
else:
final_output.append(out_shape[gather_index])
# Prevent 0-dim tensors which are not accepted by nnvm

@dominicsymes thanks for the change.
Please add a test case for this.

@srkreddy1238 thanks for taking a look.
I have added a test case that triggers strided slice with 0-dim output.
