关于python：无法上传>2GB的文件到云存储

can't upload > ~2GB to Google Cloud Storage

跟踪如下。

相关的python代码段：

1
2
3

bucket = _get_bucket(location['bucket'])
blob = bucket.blob(location['path'])
blob.upload_from_filename(source_path)

最终触发(来自SSL库)：

OverflowError: string longer than 2147483647 bytes

我想我缺少一些特殊的配置选项？

这可能与这个~1.5年前的问题有关：https://github.com/googledatalab/datalab/issues/784。

感谢您的帮助！
