Looking at the SNPE SDK 1.8.0 documentation (Reference Guide), I find under "Tensorflow Graph Compatibility" that you intended to support Slice operation. My understanding is that you supported Split operation instead. Your Tensorflow Slice Reference link is pointing infact to https://www.tensorflow.org/api_docs/python/tf/split rather than to https://www.tensorflow.org/api_docs/python/tf/slice .
Inspecting the python code, leads me to the same conclusion since in the SliceLayerResolver you are looking for operation types Split/SplitV.
Would be nice if you could support "Slice" layer. in the mean time, I suggest to correct the documentation.
