谷歌人工智能平台自定义训练：使用pandas read_csv读取谷歌云存储中的csv时出现ValueError

如何解决谷歌人工智能平台自定义训练：使用pandas read_csv读取谷歌云存储中的csv时出现ValueError

我有一个我一直在运行的自定义 gcp-ai-platform 训练作业脚本，我最后一次运行它是在 1 周前。但是，今天相同的训练作业和脚本失败并出现错误。

我试图隔离这个问题，当 Pandas 试图从谷歌云存储读取我的训练集 csv 时，我的代码坏了。我的人工智能平台训练作业和谷歌云桶属于同一个项目。

tf = "gs://bucket_name/train.csv"  
train_df  = pd.read_csv(tf)

The replica master 0 exited with a non-zero status of 1. 
Traceback (most recent call last):

我也注意到训练作业初始化时的日志有差异，额外的日志行如下：

Using mount point: /gcs
Opening GCS connection...
Set up root directory for all accessible buckets
Mounting file system "gcsfuse"
File system has been successfully mounted.

我不确定这些将如何改变 pandas read_csv 的方式。请帮忙。谢谢。
