ai平台+ gsutil权限错误：AttributeError：'GFile'对象没有属性'可读'

Question

[开始读取从gcs传输的csv文件3/13/2020时遇到错误。下载后在ai平台上检查文件权限

相关文档：https://www.tensorflow.org/api_docs/python/tf/io/gfile/GFile（似乎可读属性已被删除...）

命令：

sh.gsutil('cp',GCS_PATH,raw_rating_path)
with tf.io.gfile.GFile(raw_rating_path) as f:
   df = pd.read_csv(f)

已验证文件是本地文件，并具有以下权限：

-rw-rw-rw- 1 root root 32617551 Apr  1 20:24 /tmp/placeScores.csv

错误（从原始的AI平台日志中清除了一点：

File "/root/.local/lib/python3.7/site-packages/pandas/io/parsers.py", line 676, in parser_f
return _read(filepath_or_buffer, kwds)

Answer 1

阅读Tensor Flow文档，似乎您忘记了函数“ tf.io.gfile.GFile（raw_rating_path）”中的参数“ mode”，根据该文档，它应该是“ tf.io.gfile.GFile（ raw_rating_path，mode ='r'）“。

Answer 2

已删除tf.io.gfile.GFile线程锁定，并能够再次成功读取数据。不清楚ai平台上出了什么问题，因为它是使用tf.io.gfile.GFile在本地运行的。在ai平台tensorflow版本2.1上安装tf可能是一个问题

df = data_io.read_csv(raw_rating_path)
# with tf.io.gfile.GFile(raw_rating_path, 'r') as f:
#   df = pd.read_csv(f)
