2021-05-17MLBEDSW-4585: Resolve NumPy setup requirementDwight Lidman
This commit fixes a potential end user problem where the user needs NumPy installed in order to run setup.py. This creates a situation where if the user needs to manually install NumPy in order to install Vela. This solution moves the NumPy dependent code into the setup process and allows it to be installed as a dependency first.

2021-05-04MLBEDSW-4429: elementwise_broadcast output diffDwight Lidman
This commit fixes a regression caused by a recent commit where io_ranges and elementwise_broadcast were failing with off-by-one errors. The culprit was the incorrect usage of NATURAL rounding in cases of elementwise ADD and SUB where the input and output scales were equal and advanced scaling was not used.

2021-05-03MLBEDSW-4539: MEAN axis check exception fixDwight Lidman
A recent fix to another MEAN bug introduced a new bug. The bug was due to some incorrect logic for checking the axis attribute. Signed-off-by: Dwight Lidman <dwight.lidman@arm.com> Change-Id: I65d3486a12e029f7c4450074f03fcd1974f65d8a
2021-04-30MLBEDSW-4350 Use padding instead of skirt for merged SplitSliceHenrik G Olsson
When the operations are merged some later passes are confused by start and end coordinates for the convolution not being along the edges of the IFM, and omitting padding. But we need the zero padding to keep the output the same as before the transformation. Also fixes bug where Vela could crash if convolution had explicit start coordinate.

2021-04-29MLBEDSW-4501: Support MEAN single axis variationDwight Lidman
When a MEAN operator with a single reduction axis specifies the axis index attribute as an array with a single element rather than a scalar index, the operator is placed on the CPU even though it is technically supported. This commit fixes this issue and also adds some new tests for the axis constraints. Signed-off-by: Dwight Lidman <dwight.lidman@arm.com> Change-Id: Ia287f3b9cc80a805e972cd4b2962e52526a8dc16
2021-04-21MLBEDSW-4413: MobileNet V3 regressionDwight Lidman
This commit resolves a recent regression in multiple networks (including MobileNet V3). The regression was caused by a recent change to IFM block size calculation where a term mistakenly left out (due to it missing from the spec). The IFM microblock size has been amended for the Ethos U-55 128 config and the block size calculations now use these sizes instead (although equivalent with OFM microblock sizes).

2021-04-16MLBEDSW-3550 Only use simple scaling when bitexact with TFLiteHenrik G Olsson
For 8 bit arithmetic we cannot guarantee reproducibility in the general case since precision differs, affecting rounding near half integers. It should be safe when the ratio between output and input scales has its 12 LSBs all set to 0, however. For 16 bit arithmetic it should be sufficient to adjust the input and output scalings with a factor of 2 to get the same rounding.

2021-03-26MLBEDSW-4163: OFM zero point outside valid rangeDwight Lidman
This commit fixes a bug where the OFM zero point would assume values outside of [0, 255] due to it's usage as a stand-in for a bias when emulating the TensorFlow Lite implementation of MEAN. The solution is to adjust for the bias using an ADD operator with the bias value as an int16 const tensor. The 16-bit integer is needed as the bias is 32 bits in the original implementation but can effectively assume values in the range [-255, 255].
