【问题描述】：
我正在训练 tf slim 和
https://github.com/tensorflow/models/tree/master/slim
从头开始训练模型。发生了某种错误
我认为它的 gpu 和 cpu 运行问题。
其他代码适合我。
但是出现了这个错误
我运行以下代码
python train_image_classifier.py
--train_dir= /home/sk/workspace/slim/datasets/log
--dataset_name=imagenet
--dataset_split_name=train
--dataset_dir=/home/sk/workspace/slim/datasets/imagenet
--model_name=inception_v3
错误是
