     Parameters:
-        alpha (float, optional): Slope of the activation function at x < 0. Default: 0.01.
-        inplace (bool, optional): If inplace is True, the input and output of 
-            ``LeakyReLU`` are the same variable. Otherwise, the input and output of
-            ``LeakyReLU`` are different variables. Default False. Note that if x is
