tensorflow - 在 Cloud ML : no module object_detection. 列车上运行的 Tensorflow 对象检测错误

Question

不确定这是一个错误(文件报告)，还是我做错了什么。

系统信息:

Linux 17.04 tensorflow 版本:1.9.0 python 版本:2.7.13

我使用的命令:

gcloud ml-engine jobs submit training object_detection_$(date +%Y%m%d_%H%M%S)  \
    --job-dir="gs://mybucket/train" \
    --packages dist/object_detection-0.1.tar.gz,slim/dist/slim-0.1.tar.gz \
    --module-name object_detection.train \
    --region us-central1 \
    --config /home/me/Desktop/die_detection/config.yml \
    -- \
    --train_dir="gs://mybucket/train" \
    --pipeline_config_path="gs://mybucket/data/pipeline_cloud.config"

尝试遵循此示例，但使用我自己的数据:https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/running_pets.md

在本地工作正常。在 CloudML Engine 上运行，我得到一个非 0 退出状态。从日志来看，似乎找不到 object_detection.train。

我假设您使用的是未修改的对象检测示例。根据https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/running_pets.md#starting-training-and-evaluation-jobs-on-google-cloud-ml-engine ，--module-name 应该是 object_detection.model_main 而不是 object_detection.train。您能否仔细检查您的 dist/object_detection-0.1.tar.gz 文件？
