Error converting shape to a TensorShape: int() argument must be a string or a number, not 'tuple'._input data should be a string, not <class 'tuple'>-优快云博客

本文探讨了Python中星号(*)解包语法的使用场景，特别是在不同版本的Python环境中，*表达式在函数调用中的行为变化。文章指出，在Python 3中，*表达式的使用规则有所调整，以避免潜在的混淆，并引用了相关提案讨论。

def model_inputs(real_dim, z_dim):
#    inputs_real = tf.placeholder(tf.float32, (None, *real_dim), name='input_real')
    inputs_real = tf.placeholder(tf.float32, (None, 32,32,3), name='input_real')
    inputs_z = tf.placeholder(tf.float32, (None, z_dim), name='input_z')

    return inputs_real, inputs_z

备注：real_dim =(32,32,3)

为什么别人的代码可以使用*real_dim，我的环境下确不行？

我预计最新的Python环境下，可以成功运行；

        while current_index + batch_size <= self.shape[0]:
            data_batch = get_batch(
                self.data_files[current_index:current_index + batch_size],
#                *self.shape[1:3],
                self.image_mode,
                *self.shape[1:3])

SyntaxError: only named arguments may follow *expression

As Raymond Hettinger's answer points out, this ~~may change~~ has changed in Python 3 and here is a related proposal, which has been accepted. Especially related to the current question, here's one of the possible changes to that proposal that was discussed:

Only allow a starred expression as the last item in the exprlist. This would simplify the unpacking code a bit and allow for the starred expression to be assigned an iterator. This behavior was rejected because it would be too surprising.
