我正在尝试在自定义数据集上训练对象检测模型，但是当我在ml-engine上排队训练作业时遇到错误。几分钟后，作业失败。这是我用来启动这项工作的命令：
gcloud ml-engine jobs submit training mayemene_malaria_detector_29122018 --job-dir=${YOUR_GCS_BUCKET}/train --packages dist/object_detection-0.1.tar.gz,slim/dist/slim-0.1.tar.gz,dist/absl-py-0.6.1.tar.gz,/tmp/pycocotools/pycocotools-2.0.tar.gz --module-name object_detection.model_main --region europe-west1 --config object_detection/samples/cloud/cloud.yml --runtime-version=1.12 -- --model_dir=${YOUR_GCS_BUCKET}/train --pipeline_config_path=${YOUR_GCS_BUCKET}/data/ssd_mobilenet_v1_coco.config
这是ml-engine日志的快照：

这很可能是由于ssd_mobilenet_v1_coco.config
fine_tune_checkpoint: "gs://uganda-plasmodium-training-ml/model.ckpt"
更改此行以匹配预先训练的移动网络检查点所在的存储桶 有所作为。请有人能告诉我为什么会出现此错误吗？
