tensorflow 1.5 TypeError: __init__() got an unexpected keyword argument 'dct_method'

在运行 objection_detection 下的train进行训练的时候报错 如下:

stack overflow 提到解决方案 https://stackoverflow.com/questions/48920762/tensorflow-error-typeerror-init-got-an-unexpected-keyword-argument-dct

tensorflow issue也再次提到.https://github.com/tensorflow/models/issues/3421

具体解决方案如下

This error is due to the incompatibility of file tf_example_decoder.py with the Tensorflow installed.

In file models/research/object_detection/data_decoders/tf_example_decoder.py:

line 28:

slim_example_decoder = tf.contrib.slim.tfexample_decoder

line 104:

self.items_to_handlers = {

fields.InputDataFields.image:

slim_example_decoder.Image(

image_key=’image/encoded’,

format_key=’image/format’,

channels=3,

dct_method=dct_method),….

…..

….

..

.

}

slim_example_decoder.Image is tf.contrib.slim.tfexample_decoder.Image

In Tensorflow 1.5 source code tf.contrib.slim.tfexample_decoder.Image doesn’t have dct_method argument. Therefore when dct_method argument is passed it throws an error.

A simple hack would be to not pass this argument. So edit tf_example_decoder.py line 110 to remove dct_method=dct_method. I tried this and it worked and didn’t had any effect on training.

将 dct_method=dct_method 给去掉.
