GitHub教程上Google Cloud Healthcare API的ExportDicomData请求始终未完成

Question

我正在尝试云医疗应用编程接口GitHub教程上的ML Codelabs的AutoML愿景。https://github.com/GoogleCloudPlatform/healthcare/blob/master/imaging/ml_codelab/breast_density_auto_ml.ipynb

我运行了Convert DICOM to JPEG部分的Export DICOM data cell代码，请求以及所有的前提单元代码都成功了。

但是等待操作完成会超时并且永远不会结束。(数据集页面上的ExportDicomData请求状态全天保持“运行”。我做了很多次，但所有的请求都堆积在一起，一直在“运行”。有几次我尝试从头开始做，结果都是一样的。)

到目前为止，我做到了：

1)删除output_config，因为出现无效参数错误。https://github.com/GoogleCloudPlatform/healthcare/issues/133

2)开启云资源管理器API，因为您需要它。

这是手机号码。

# 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。

  }
}

     18   print('Success!')
     19   return response

AssertionError: operation did not complete successfully in time limit

接口版本为v1beta1。

我想知道是否有人有什么建议。

谢谢。

Answer 1

经过几次不断的尝试和一夜的坚持，它终于成功了。我也不知道原因。

codelabs最近有一次更新。错误消息是由codelab中的超时引起的，而不是由于实际操作。这个问题已经在更新中得到了解决。如果您仍然遇到任何问题，请让我知道！
