python - 尝试训练模型时出现 TensorFlow 错误

问题描述

运行时出错python train.py --logtostderr --train_dir = training / --pipeline_config_path = training / faster_rcnn_inception_v2_pets.config

    \trainer.py:260: create_global_step (from tensorflow.contrib.framework.python.ops.variables) is deprecated and will be removed in a future version.
Instructions for updating:
Please switch to tf.train.create_global_step

以下：https ://github.com/satendrapandeymp/object_detection 我已经成功地使用网络摄像头实现了对象检测 api 测试，但现在这是在训练模型上，这些错误不断出现

然而，来自 Python 本机 cmd 运行的另一个错误。 

 python train.py --logtostderr --train_dir = training / --pipeline_config_path = training / faster_rcnn_inception_v2_pets.config

解决方案

没有看到代码有点难以判断，但似乎文件存在问题FLAGS.pipeline_config_path并且Windows无法找到该文件，或者没有读取它的权限。

也许是因为当您设置参数的值时，就像training / faster_rcnn_inception_v2_pets.config您在之前和之后使用空格一样"/"。

看来这是Tensorflow的Github中已经报告的一个问题，也许你可以在这个链接中找到解决方案。
