te.lang.cce.vlog(raw_tensor)

Performs the logarithmic ln(x) operation on each element in raw_tensor. The supported type is float16. The data types int8, uint8, int32, and float32 are converted to float16.

This API is defined in elewise_compute.py.

Parameter Description

raw_tensor: input tensor, tvm.tensor type

Return Value

res_tensor: ln(raw_tensor), tvm.tensor type

Calling Example

shape = (1024,1024)
input_dtype = "float16"
data = tvm.placeholder(shape, name="data", dtype=input_dtype)
res = te.lang.cce.vlog(data)
