2020-11-19[MLBEDSW-3300] Fix DepthwiseConv2D fails when bias tensor quant_values are NoneFredrik Svedberg
Fixed DepthwiseConv2D fails when bias tensor quant_values are None. Also fixed DepthwiseConv2D fails with implicit depth multiplier. Signed-off-by: Fredrik Svedberg <fredrik.svedberg@arm.com> Change-Id: I799a565eefa498ccf7ac626fcd472b8cbd908931
2020-11-16MLBEDSW-3301: Vela fails ungracefully when reading string buffersDwight Lidman
When encountering a sparse string buffer, Vela fails both due to missing a mapping for a Numpy string type and also for not being able to read sparse buffers. The failing line is attempting to reshape a [100] buffer into a [3, 5] tensor which does not work due to Vela treating the buffer as non-sparse. The solution here is to simply not do the reshape for string buffers (which all appear to be sparse) since it is not something that will be supported in the future anyway. The related operator can then be pushed to the CPU as expected. Signed-off-by: Dwight Lidman <dwight.lidman@arm.com> Change-Id: Iea0af6cd60a691f975209014b6aa098dde8d6a4b

2020-08-12MLBEDSW-2637 Utilise new tensor and operator funcsMichael McGeagh
add_input_tensor, set_output_tensor, create_const_tensor and create_reshape_tensor have recently been added. This replaces all found existing instances with these new helper functions Signed-off-by: Michael McGeagh <michael.mcgeagh@arm.com> Change-Id: If33be8dbf237b2087b562b03cdeb51da1f99a786
2020-08-12MLBEDSW-2383 Preserve previous metadataMichael McGeagh
The input tflite file potentially has metadata attached to it, which was lost when writing the vela optimised tflite file out. This patch preserves any metadata found. Signed-off-by: Michael McGeagh <michael.mcgeagh@arm.com> Change-Id: I7b4e941696d21b81802fd4398cd405323778bedf
2020-08-04MLBEDSW-2574: Fix issue with different bias tensor scalingTim Hall
- In networks that share the scale & bias tensor between operators, differences in operator quantization causes conflicting HW packed scale & bias values for the tensor. This commit replicates the scale and bias tensors per operator, similar to weights handling, to avoid this conflct.

2020-08-03MLBEDSW-2603 Missing "new_shape" attrib in ReshapeMichael McGeagh
Reshape ops should contain a "new_shape" attribute. An invalid tflite file without this attribute caused vela to crash. The new_shape however is the same as the output shape, so if missing, we can easily add this missing attribute.

2020-06-18MLBEDSW-1941: Bug fix shared weightsLouis Verhaard
If same weight tensor was used with different block configs, errors would occur. Fixed by always cloning weight tensors, using a global weight compression cache and modifying the linear allocator to detect multiple usage of same weight compression.

2020-06-18MLBEDSW-2372: Failing assert for ResizeBilinear with upscale != 2xDwight Lidman
This commit fixes the failing assert by removing it and instead placing unsupported ResizeBilinear operators on the CPU. It introduces a new graph optimisation function which adds the necessary attributes as well as new operator restrictions for ResizeBilinear.

2020-06-18MLBEDSW-1971: Verify ifm block size calculation against specificationDwight Lidman
This commit ensures the IFM block size calculation in architecture_features.py matches the specification by correctly setting the ifm upscaling factor based on the upscaling mode. This requires adding an attribute to the Tensor object which stores the upscaling mode for that specific tensor and making sure that information is correctly carried over to shared_buffer_allocation.py.

2020-06-18MLBEDSW-1498: Add Resize_Bilinear operator supportDwight Lidman
This patch adds support for the ResizeBilinear operator. It is implemented using a 2x2 Nearest Neighbor upscale followed by a 2x2 Average Pool. Depending on the argument align_corners the output is either of shape: - (2 * M, 2 * N) when align_corners == True, or - (2 * M - 1, 2 * N - 1) when align_corners == False where (M, N) is the input shape. The padding mode is SAME when align_corners == True and VALID when align_corners == False. The argument half_pixel_centers is out of scope and is as of now ignored. Note that only upscaling by a factor of 2 is supported. Change-Id: Ia6d6d010c4f1bb13f5f839bc8d16872a626d9a3b Signed-off-by: Dwight Lidman <dwight.lidman@arm.com>
2020-06-18Add pre-commit support for sanity checksDiego Russo
Use pre-commit framework [1] to run black and flake8 before the commit. black and flake8 are managed by the pre-commit framework and they can be run manually by the user using `pre-commit run` command. Fix the code base with the help of black and flake8. Fix import statements according to PEP8 guidelines [1] Both tools have the following settings (specified in the pre-commit configuration file): * line length: 120 characters * directory to exclude: ethosu/vela/tflite/ and ethosu/vela/ethos_u55_regs Updated README.md on how to install pre-commit and how to run sanity checks. Pipenv files have been updated including new dependencies for pre-commit.
