2022-04-21MLBEDSW-5384 FC layers run on NPU if underlying shape is 2DAyaan Masood
*Added generic function which checks if underlying shape of FullyConnected operation is 2D and performs shape reduction *Fully connected operation >2 dimensions now run on NPU if the above case is satisfied *constraint_fc_output_2d and rewrite_fully_connected_input refactored *Added unit test to confirm this functionality Signed-off-by: Ayaan Masood <Ayaan.Masood@arm.com> Change-Id: I0e29c767e5b84841eb53bbc44464b36a454f7b38
2022-04-20MLBEDSW-6407: Vela fails with TypeError in npu_performanceTim Hall
- This is due to calling range() on a non-integer value which in turn is due to a change in the behaviour of round() on numpy.float64 values - The fix is to always force the output of the round() to be an integer and thereby stop whole number floating point values propagating into the kernel dimensions which later feed into the range().

2022-03-21MLBEDSW-6298: MLCE: Unable to find a valid block configTim Hall
- Fixed a bug due to ResizeBilinear modifying the attributes of a shared IFM - The ifm_resampling_mode is now an attribute of an operator rather than a tensor - Changed all calls to try_block_config() to use the attribute rather than recalculating it in multiple places Signed-off-by: Tim Hall <tim.hall@arm.com> Change-Id: I4641e9cd6b049bd4186776d98e3e751c5e5bcc06

2022-03-11Vela: Fix diff in mean opDiqing Zhong
- Extend ifm/ofm dimensions explicitly in mean op This fix a bug when ifm/ofm shape has different dimensions e.g. IFM=1x19x18x25 axis=2 OFM=1x19x25, the ofm_shape should be 1x19x1x25, not 1x1x19x25 - Fix wrong weight shape Change-Id: I269eb71ea56c09deee2aa6c6433d9b2baa98a113 Signed-off-by: Diqing Zhong <diqing.zhong@arm.com>
2022-02-24MLBEDSW-6247: MLCE: Issue when running a model with PaddingTim Hall
- The bug is that TransposeConv does not support explicit padding which is needed in order to combine it with a proceeding Pad op - The fix is to exclude such combination Signed-off-by: Tim Hall <tim.hall@arm.com> Change-Id: Ide03d034dc32b5fc9bcaaf291ab713482223a042
2022-02-02MLBEDSW-3623: Diff on semantic_segmentationRickard Bolin
The root cause of this diff is precision errors caused by rounding several times when performing a resize bilinear upscaling to more than twice the initial size. This is solved by rewriting the algorithm to perform nearest neighbour upscaling to the correct size and then applying one larger average pool instead of several 2x2 pools. Avgpool with padding is limited to kernel size 8x8, which constraints the largest possible bilinear upscaling to 8 times the input size.

2021-12-20MLBEDSW-5844: Inconsistent calculation of read shapesTim Hall
- This bug causes a regression in the use of unpack and split operators - The bug is due to the read_shapes attribute being an absolute calculation for slice and strided_slice, but a relative one for unpack and split - The fix is to consistently treat the attribute as a shape relative to the read_offset Signed-off-by: Tim Hall <tim.hall@arm.com> Change-Id: I4504b161be507ea22ca6ee40fbe7808bfe049405

2021-11-05MLBEDSW-5209 Vela: output diff depthwise with non-zero zero pointsFredrik Svedberg
Fixed by adjusting zero points for ops with int8 IFM and asymmetric weights since the reference does not support asymmetric weights for int8 IFM and ignores the zero points. Signed-off-by: Fredrik Svedberg <fredrik.svedberg@arm.com> Change-Id: I2a206a01a471a53aa864a6a3616aa23d2a5a23c8
2021-10-28MLBEDSW-5440 MLCE: Vela crashing due to mismatch in padding shape in OFMJames Ward
Change convert_pad optimiser to use op.ifm_shapes attribute in place of the fickle op.ifm.shape (which in this case had changed due to the optimised-out reshape) Signed-off-by: James Ward <james.ward@arm.com> Change-Id: I13fbd846ac8d3342afd7844d1041cfa15aaae124

2021-07-08MLBEDSW-4838 Added basic TOSA support.Patrik Gustavsson
Added basic TOSA support, enabling Vela to read and compile a .tosa file corresponding to CONV2D + Rescale + Clamp, and writing it to an optimized .tflite file. The optimized .tflite file, will in this case, hold a commandstream where the Rescale and Clamp has been fused into the CONV2D. The optimized tflite file is not output from Vela. -Added support to read .tosa file into Vela internal structure. - Added tosa_reader.py, tosa_mapper.py and helper files stored under tosa/ - Support for this limited to ~10 ops -Added reader_util.py for functions common for TOSA and TFLite -Added tosa_graph_optimiser.py -Added support to fuse Rescale into convolution -Modified handling for padding -Added support to fuse Clamp to previous op -Added graph_optimiser_util.py -Moved functions common for TOSA/TFLite graph optimization to this file. -Renamed graph_optimiser.py to tflite_graph_optmiser.py -Added separate tosa_supported_operators.py -Added supported_operator_util.py -For functions in common for TOSA/TFLite Signed-off-by: Patrik Gustavsson <patrik.gustavsson@arm.com> Change-Id: Ic3c540504ec8c5eb4771397fdc6882050ecf33ab
