Question

我真的是Google Cloud Platform的新生。我正在尝试使用从存储区对象CSV文件提取的数据填充BigQuery表。我创建了一个Python测试脚本来创建和填充表。创建完成，但是当我运行文件时，我陷入了困境。

我的脚本：

from google.cloud import bigquery
from google.cloud.bigquery import LoadJobConfig
from google.cloud.bigquery import SchemaField

client = bigquery.Client()
dataset_ref = client.dataset('datasetname')


## Create the table

schema = [
    bigquery.SchemaField('start_date', 'DATETIME', mode='NULLABLE'),
    bigquery.SchemaField('start_station_code', 'INTEGER', mode='NULLABLE'),
    bigquery.SchemaField('end_date', 'DATETIME', mode='NULLABLE'),
    bigquery.SchemaField('end_station_code', 'INTEGER', mode='NULLABLE'),
    bigquery.SchemaField('duration_sec', 'INTEGER', mode='NULLABLE'),
    bigquery.SchemaField('is_member', 'INTEGER', mode='NULLABLE')
]
table_ref = dataset_ref.table('tablename')
table = bigquery.Table(table_ref, schema=schema)
table = client.create_table(table)  # API request

## Loading data


SCHEMA = [
    SchemaField('start_date', 'DATETIME', mode='NULLABLE'),
    SchemaField('start_station_code', 'INTEGER', mode='NULLABLE'),
    SchemaField('end_date', 'DATETIME', mode='NULLABLE'),
    SchemaField('end_station_code', 'INTEGER', mode='NULLABLE'),
    SchemaField('duration_sec', 'INTEGER', mode='NULLABLE'),
    SchemaField('is_member', 'INTEGER', mode='NULLABLE')
]
#table_ref = client.dataset('dataset_name').table('table_name')

load_config = LoadJobConfig()
load_config.skip_leading_rows = 1
load_config.schema = SCHEMA
uri = 'gs://gcp-development/object.csv'

load_job = client.load_table_from_uri(
    uri,
    table_ref,
    job_config=load_config)

load_job.result()

destination_table = client.get_table(table_ref)
print('Loaded {} rows.'.format(destination_table.num_rows))

按照documentation，这似乎是正确的。但是，我遇到了我不理解的以下错误，并且我不知道如何查看日志以获取更多详细信息。

错误：

google.api_core.exceptions.BadRequest: 400 Error while reading data, error message: CSV table encountered too many errors, giving up. Rows: 1; errors: 1. Please look into the error stream for more details.

错误流在哪里？我尝试过：

GET https://www.googleapis.com/bigquery/v2/projects/projectId/queries/jobId

在troubleshooting documentation之后，但我什么也没找到。

感谢您的帮助。
