Short description
my program try to get url https://www.googleapis.com/storage/v1/b/tfds-data/o/dataset_info%2Fcnn_dailymail%2Fplain_text%2F3.0.0?fields=size%2Cgeneration%2Cupdated,but failed

2020-08-20 08:41:35.983921: W tensorflow/core/platform/cloud/google_auth_provider.cc:178] All attempts to get a Google authentication bearer token failed, returning an empty token. Retrieving token from files failed with "Not found: Could not locate the credentials file.". Retrieving token from GCE failed with "Aborted: All 10 retry attempts failed. The last failure: Unavailable: Error executing an HTTP request: libcurl code 6 meaning 'Couldn't resolve host name', error details: Couldn't resolve host 'metadata'".
2020-08-20 08:42:37.024931: E tensorflow/core/platform/cloud/curl_http_request.cc:596] The transmission of request 0x5622d3c080e0 (URI: https://www.googleapis.com/storage/v1/b/tfds-data/o/dataset_info%2Fcnn_dailymail%2Fplain_text%2F3.0.0?fields=size%2Cgeneration%2Cupdated) has been stuck at 0 of 0 bytes for 61 seconds and will be aborted. CURL timing information: lookup time: 0.078541 (No error), connect time: 0 (No error), pre-transfer time: 0 (No error), start-transfer time: 0 (No error)

Start by reproducing the dataset metadata request and read the warnings from tensorflow/core/platform/cloud/google_auth_provider.cc and tensorflow/core/platform/cloud/curl_http_request.cc. Check the reported missing credentials and failed metadata-host lookup, then determine whether the request completes successfully without the authentication and network errors.
