我正在 Cloud Healthcare API GitHub 教程上尝试 ML Codelabs 的 AutoML Vision。 https://github.com/GoogleCloudPlatform/healthcare/blob/master/imaging/ml_codelab/breast_density_auto_ml.ipynb
我运行将 DICOM 转换为 JPEG 部分的导出 DICOM 数据单元代码，请求以及所有前提单元代码都成功。
但是等待操作完成会超时并且永远不会完成。（数据集页面上的 ExportDicomData 请求状态在一天内保持“正在运行”。我做了很多次，但所有请求都堆积在“正在运行”。有几次我尝试从头开始做，结果是一样的。）
到目前为止我做了：
1) 删除“output_config”，因为发生 INVALID ARGUMENT 错误。 https://github.com/GoogleCloudPlatform/healthcare/issues/133
2) 启用 Cloud Resource Manager API，因为它是需要的。
这是单元格代码。
# Path to export DICOM data.
dicom_store_url = os.path.join(HEALTHCARE_API_URL, 'projects', project_id, 'locations', location, 'datasets', dataset_id, 'dicomStores', dicom_store_id)
path = dicom_store_url + ":export"
# Headers (send request in JSON format).
headers = {'Content-Type': 'application/json'}
# Body (encoded in JSON format).
# output_config = {'output_config': {'gcs_destination': {'uri_prefix': jpeg_folder, 'mime_type': 'image/jpeg; transfer-syntax=1.2.840.10008.1.2.4.50'}}}
output_config = {'gcs_destination': {'uri_prefix': jpeg_folder, 'mime_type': 'image/jpeg; transfer-syntax=1.2.840.10008.1.2.4.50'}}
body = json.dumps(output_config)
resp, content = http.request(path, method='POST', headers=headers, body=body)
assert resp.status == 200, 'error exporting to JPEG, code: {0}, response: {1}'.format(resp.status, content)
print('Full response:\n{0}'.format(content))
# Record operation_name so we can poll for it later.
response = json.loads(content)
operation_name = response['name']
这是等待的结果。

我想知道是否有人有任何建议。
谢谢你。
