我使用tensorflow incpetion_v3网络进行特征提取。我收到以下错误：
_, end_points = inception_v3.inception_v3(images, is_training=False, num_classes=1001)
File "/home/osman/viennaclassification/models/slim/nets/inception_v3.py", line 525, in inception_v3
end_points['Predictions'] = prediction_fn(logits, scope='Predictions')
TypeError: sigmoid() got an unexpected keyword argument 'scope'
