分布式Tensorflow：TypeError：__ init __（）为关键字参数'dtype'获取了多个值

Question

在inception distributed training tutorial之后运行分布式张量流时，我遇到以下错误：

Traceback (most recent call last):

    shape.as_list(), dtype=dtype, partition_info=partition_info)
TypeError: __init__() got multiple values for keyword argument 'dtype'

我认为这个问题是由于slim中某处的api不匹配造成的。我使用的tensorflow版本是v1.0.0-alpha。有人可以帮我吗？提前谢谢！

Answer 1

问题解决了。这可能是由于api不匹配。解决方案是将inception/slim/variables.py中的第243行更改为initializer=tf.zeros_initializer()。

请告诉我是否有任何错误。
