Question

然后我尝试用

训练模型

  python3 model_main.py —logtostderr —train_dir=training/ —pipelnie_config_path=training/ssd_mobilenet_v1_pets.config

我收到以下错误。设置所有配置。首先，我在Mac上试用了它，然后开始了。但是培训过程花了很长时间在CPU上，我决定使用GPU（paperspace）进行云计算。我所做的一切完全一样，并得到了这个错误。显示所有文件。我做错了什么？配置文件似乎有问题

Answer 1

您的命令中有一个错字。应该是

pipeline_config_path

代替

pipelnie_config_path

如果您使用model_main.py运行，参数--model_dir而不是-train_dir带有双破折号吗？
