Hi @ZJay07
Thank you very much for the PR
I think there are other dtypes that the native tf does support like tf.float16
as maybe checked with

import tensorflow as tf
x = tf.constant([0.5], dtype=tf.float16)
tf.math.softplus(x)

does the test not pass for dtypes other float32 and float64?

[ZJay07]

Hey @Ishticode, I tried rerunning the test again adding float16 and got this error, does this means tf.math.softplus does not support float16?

ivy.utils.exceptions.IvyBackendException: paddle: softplus: paddle: abs: (NotFound) The kernel with key (CPU, Undefined(AnyLayout), float16) of kernel `abs` is not registered. Selected wrong DataType `float16`. Paddle support following DataTypes: int32, int64, float64, complex128, float32, complex64.

[Ishticode]

This error means the paddle backend is unable to run this function with float16. You will need to specify float16 as unsupported for ivy's softplus function paddle backend. Does that make sense?

[ZJay07]

Just fixed it and including float16, is this the right way to do it?

[Ishticode]

can this be specified as unsupported in paddle backends softplus implementation?

[ZJay07]

Sorry, forgot to update this, will fix it right away!

[Ishticode]

Thank you. Looks good to merge :)
