google-api-python-client因OAuth2而损坏? [英] google-api-python-client broken because of OAuth2?

问题描述

我正在尝试使用Python中的Google Api客户端检查bigquery中是否存在某个数据集.直到最后一次更新我都遇到了这个奇怪的错误，我不知道该如何解决:

I am trying to check if a certain dataset exists in bigquery using the Google Api Client in Python. It always worked untill the last update where I got this strange error I don't know how to fix:

AssertionError: PID check failed. RNG must be re-initialized after fork(). Hint: Try Random.atfork()

有人了解发生了什么事吗?

Is someone understanding what is hapening?

请注意，我也遇到了其他错误，例如GCStorage.

Note that I also get this error with other bricks like GCStorage.

还请注意，我使用以下命令来加载我的Google凭据:

Note also that I use the following command to load my Google credentials:

from oauth2client.client import GoogleCredentials

def get_credentials(credentials_path):  #my json credentials path
    logger.info('Getting credentials...')
    try:
        os.environ['GOOGLE_APPLICATION_CREDENTIALS'] = credentials_path
        credentials = GoogleCredentials.get_application_default()
        return credentials
    except Exception as e:
        raise e

因此，如果有人知道使用我的json服务帐户文件加载我的Google凭据的更好方法，并且可以避免该错误，请告诉我.

So if anyone know a better way to load my google credentials using my json service account file, and which would avoid the error, please tell me.

推荐答案

该错误似乎出在PyCrypto模块中，该模块似乎由Google的OAuth2实现在后台使用.如果您的代码在某个时候正在调用os.fork()，则可能需要在父进程和子进程中随后都调用Crypto.Random.atfork()，以更新模块的内部状态.

It looks like the error is in the PyCrypto module, which appears to be used under the hood by Google's OAuth2 implementation. If your code is calling os.fork() at some point, you may need to call Crypto.Random.atfork() afterward in both the parent and child process in order to update the module's internal state.

有关PyCrypto文档的信息，请参见此处；搜索"atfork"以获取更多信息: https://github.com/dlitz/pycrypto

此问题和答案可能也与之相关: PyCrypto:AssertionError("PID检查失败.必须在fork()之后重新初始化RNG.提示:请尝试Random.atfork())

This question and answer might also be relevant: PyCrypto : AssertionError("PID check failed. RNG must be re-initialized after fork(). Hint: Try Random.atfork()")
