Question

我已经完成了tensorflow对象检测API的所有安装步骤。我已经检查了一些有关正确安装的指南，只是为了确保我正确地进行了安装。但是我仍然一次又一次收到此错误：

我正在使用一个非常小的训练集（15张图像），只是为了掌握整个过程-当然，稍后我会添加更多内容以确保准确性。我会提及这一点，以防万一。

我怀疑配置文件，train.py文件本身（相对于我的数据集）或.record文件有问题。但是对我来说，一切似乎都符合要求。

我正在使用ssd_mobilenet_v1_coco_11_06_2017数据集和ssd_mobilenet_v1_pets配置。

任何提示都非常感谢。如果我遗漏了必要的详细信息，请告诉我。

我在python版本3.7（MacOS 10.13.4）中也遇到了同样的问题，我重新检查了.config文件中给出的路径，但这是正确的。我可以通过将python降级到version2.7并在tensorflow对象识别中遵循相同的安装步骤，并在schedule文件中搜索.config并删除下面的代码块来解决该问题。

schedule { step: 0 learning_rate: .0001 }

然后运行

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

这可能是由于版本不匹配所致。
