the snippet output is different from what quantize conv expect

[Knight-X]

in the conv snippet, ctx.add(new RamTensor(), "out_conv_eightbit_quantized_conv:0", 2); ctx.add(new RamTensor(), "out_conv_eightbit_quantized_conv:1", 2); (output min) ctx.add(new RamTensor(), "out_conv_eightbit_quantized_conv:2", 2); (output max) ctx.push(new QntConvOp<uint8_t, uint8_t, float>({ 1, 2, 2, 1 }, VALID), { "x_quint8_const:0", "w_filter_quint8_const:0", "x_min:0", "x_max:0", "w_filter_min:0", "w_filter_max:0" }, { "out_conv_eightbit_quantized_conv:0", "out_conv_eightbit_quantized_conv:1", "out_conv_eightbit_quantized_conv:2" });

in matmul snippet, ctx.add(new RamTensor(), "z_eightbit_quantized_mat_mul:0", 2); ctx.add(new RamTensor({1}), "z_eightbit_quantized_mat_mul:1", 2); ctx.add(new RamTensor({1}), "z_eightbit_quantized_mat_mul:2", 2); ctx.push(new QntMatMulOp<uint8_t, uint8_t, int>(), { "w_quint8_const:0", "w_min:0", "w_max:0", "x_quint8_const:0", "x_min:0", "x_max:0" }, { "z_eightbit_quantized_mat_mul:0", "z_eightbit_quantized_mat_mul:1", "z_eightbit_quantized_mat_mul:2" });

The dim of output min and output max of Quantized MatMul is given by codegen , and it is as same as Quantized Conv2d. however, the second and third output does not have dim.

This should be fixed at develop branch. I'll close it when we merge develop into master https://github.com/uTensor/utensor_cgen/blob/develop/utensor_cgen/snippets/templates/snippets/conv2d_op.cpp
