Set the input and output tensors.
[in] | input | Source tensor. 3 lower dimensions represent a single input [width, height, IFM], while every optional dimension from 4 and above represent a batch of inputs. Data types supported: F32. |
[in] | weights | Weights tensor. Weights are 4D tensor with dimensions [kernel_x, kernel_y, IFM, OFM]. Data type supported:Same as input . |
[in] | biases | Biases tensor. Shared biases supported. Biases are 1D tensor with dimensions [OFM].Data type supported: Same as input |
[out] | output | Destination tensor. 3 lower dimensions represent a single output [width, height, OFM], while the rest represent batch of outputs. Data types supported: Same as input . |
[in] | conv_info | Contains padding and stride information described in PadStrideInfo. |
[in] | act_info | (Optional) Activation layer information in case of a fused activation. |
[in] | enable_fast_math | (Optional) Enable fast math computation. Unused for Neon backend. |
