a277c7ddb3 Refactor OpGen. ()
Also fixes op lists when the same attribute specifies the length of
both an input and an output.  I added a test of "shapeN" which
previously failed with the following error:

    ERROR: Ran out of counts in toResult. Likely misuse of buildListOp.

2b5e41ffeb Make code --pedantic ()
* Enforce pedantic build mode in CI.
* Our imports drifted really far from where they should be.

69fdbf677f test case to show can't calculate grad for embedding (and associated fix) ()
* Fix for embedding gradient calculation

- Passes vectors instead of scalars to slice
- converts the numRows to a scalar
- add `toScalar` utility function
- minor change to test case so that it actually works

* added lib for testing helper functions

* add flatSlice function

fc3d398ca9 Optimize fetching ()
* Add MNIST data to gitignore
* Add simple tensor round-trip benchmark
* Use deepseq + cleaner imports
* Use safe version of fromIntegral in FFI code
* Don't copy data when fetching tensors

d9115c716f genericLength is too generic.
Avoid folding in TF.

ec5c5228e1 Fixed by adding previously missing reshape.
The comment did say that only flat shapes were supported though.

03a3a6d086 Misc MNIST example cleanup ()
* Use native oneHot op in the example code. It didn't exist when this was originally written.
* Misc cleanup in MNIST example

- Use unspecified dimension for batch size in model. This simplifies the
  code for the test set.
- Move error rate calculation into model.
