Question

我使用Python从Adwords下载一些报告，然后使用pandas重新格式化数据。

import pandas as pd
from googleads import adwords

    stream_data = downloader.DownloadReportWithAwql(
        products_query,
        'CSV', output_file,
        client_customer_id='xxxxx',
        skip_report_header=True,
        skip_report_summary=True,
        skip_column_header=False)

    data = pd.read_csv(output_file,
                       sep=',',
                       encoding='utf-8-sig',
                       header=1,
                       error_bad_lines=False,
                       warn_bad_lines=False)
    print(data)

生成的文件如下所示：

647972293,695588-4,enabled,enabled,1,0.00,2017-04-01,2,50.00%,0.00%,0.00,350000,0.00

但是，出于某种原因我收到此错误：

Traceback (most recent call last):

    error_bad_lines=False)

  File "pandas/parser.pyx", line 2014, in pandas.parser.raise_parser_error (pandas/parser.c:26862)
TypeError: raise: exception class must be a subclass of BaseException

我尝试了一些不同的侵蚀类型，但仍然相同......任何想法？

并尝试将分隔符转换为字符串？

class CassandraJournal(implicit val system: ActorSystem) {

 def engageStreaming = {
   val readJournal = PersistenceQuery(system).readJournalFor[CassandraReadJournal](CassandraReadJournal.Identifier)
   implicit val mat = ActorMaterializer()

   readJournal.eventsByTag("account", Offset.noOffset)
     .runForeach { event => println(event) }
   }
}

从Adwords下载数据并使用Pandas读取文件
