Hello,@leandron . I found in [cmsis.py](https://github.com/apache/tvm/blob/ff3716b83a72c2ff261c492f259e1fcd260600ce/python/tvm/relay/op/contrib/cmsisnn.py#L90) that the scale of softmax must be 1/256 and the zero point must be -128. Why is that? According to the formula Q(x_fp32, scale, zero_point) = round(x_fp32/scale) + zero_point, scale and zp should be adjustable (for example, in the case where scale is 1/128 and zp is 0, it should still meet the conditions for int8), right? -- This is an automated message from the Apache Git Service.
