【报错相关】TypeError: softmax() got an unexpected keyword argument 'axis'

出现这个问题，有几种解决办法，可以调低一下keras的版本，比如：

pip install keras==2.1

不过还有个更方便的方法，从错误可知softmax中不包含axis这个参数，那么把axis参数替换成dim就可以了。源代码是这样的：

def softmax(x, axis=-1):
    """Softmax of a tensor.

    # Arguments
        x: A tensor or variable.
        axis: The dimension softmax would be performed on.
            The default is -1 which indicates the last dimension.

    # Returns
        A tensor.
    """
    return tf.nn.softmax(x, axis=axis)

更改成这样：

def softmax(x, axis=-1):
    """Softmax of a tensor.

    # Arguments
        x: A tensor or variable.
        axis: The dimension softmax would be performed on.
            The default is -1 which indicates the last dimension.

    # Returns
        A tensor.
    """
    return tf.nn.softmax(x, dim=axis)

就是改了最后一行。
