python-3.x - 语法错误 : invalid syntax while running Job

Question

作业是从终端使用以下命令启动的；

gcloud ml-engine jobs submit training barcode_detection_eight --runtime-version 1.8 --job-dir gs://barcode-object-detection/model_dir --packages dist/object_detection-0.1.tar.gz,slim/dist/slim-0.1.tar.gz,../../pycocotools/pycocotools-2.0.tar.gz --module-name object_detection.model_main --region us-central1 --config object_detection/samples/cloud/cloud.yml -- --model_dir=gs://barcode-object-detection/model_dir --pipeline_config_path=gs://barcode-object-detection/data/faster_rcnn_resnet101_pets.config

5 分钟后，作业因以下错误而终止；

ps-replica-2 Command '['python3', '-m', 'object_detection.model_main', '--model_dir=gs://barcode-object-detection/model_dir', '--pipeline_config_path=gs://barcode-object-detection/data/faster_rcnn_resnet101_pets.config', '--job-dir', 'gs://barcode-object-detection/model_dir']' returned non-zero exit status 1

还收到以下一系列无效语法错误；

这个错误是什么意思？我用文档仔细检查了命令语法，但仍然收到此错误。专家的帮助将不胜感激。

根据runtime version list , 机器学习引擎不提供对 matplotlib 包的访问。如果删除依赖项，应用程序会工作吗？
