…ai#7422) Improved TiledMLP and SequenceTiledCompute for bs>1 This PR: - extends the testing utils to add `CaptureStd*`, `CaptureLogger` context managers - extends the test to run both bs=1 and bs=2 - use an uneven seqlen to test varlen shards - flattens bs+seqlen dim, to avoid problems with grad tensor strides when bs>1 - mlp doesn't care for the bs dimension so using a pretend `bs*seqlen` seqlen instead and restoring the shape at the end for the grad. --------- Signed-off-by: Stas Bekman <[email protected]> Co-authored-by: Logan Adams <[email protected]>
