Hey @Aaryan562, thanks a lot for looking into this failing test. Could you please link this issue in the PR title. Also, I'm not sure if I follow why we shouldn't be testing for gradients in this function, could you please explain why it is necessary to set test_gradients as False in this?

ivy.utils.exceptions.IvyBackendException: paddle: mean: (NotFound) The kernel with key (CPU, Undefined(AnyLayout), float16) of kernel `mean` is not registered. Selected wrong DataType `float16`. Paddle support following DataTypes: float64, complex128, float32, complex64, bool.
E         [Hint: Expected kernel_iter == iter->second.end() && kernel_key.backend() == Backend::CPU != true, but received kernel_iter == iter->second.end() && kernel_key.backend() == Backend::CPU:1 == true:1.] (at /paddle/paddle/phi/core/kernel_factory.cc:199)

@hello-fri-end Basically when paddle was taking float16 dtype and test_gradients flag was set to True it gave the above error. So in my latest commit I have focused on that but I am not quite sure why is error for this condition. Maybe your inputs could help.
