Tensorboard/tensorflow 与 s3 logdir -curl 返回错误代码 6

Question

一直在尝试使用大量设置/env-vars/tf-versions，但不起作用..

在我的本地机器上，这是有效的：AWS_ACCESS_KEY_ID=XXX AWS_SECRET_ACCESS_KEY=XXX AWS_REGION=eu-west-1 tensorboard --logdir="s3://my-bucket/tflogs/"

在 AWS 实例上，这将抛出：

在https://github.com/tensorflow/tensorflow/issues/16397 中没有找到任何提示

并且没有明确的线索差异可能在哪里，我已确保具有相同的tensorflow/tensorboard版本（1.8.0）。也会发生在指定 s3 tensorboard logdir 的情况下运行 tensorflow 的情况。

像这样解决了：

export AWS_ACCESS_KEY_ID=<access key id>
export AWS_SECRET_ACCESS_KEY=<secret access key>
export AWS_REGION=us-west-2
export S3_REGION=us-west-2
export S3_ENDPOINT=s3.us-west-2.amazonaws.com
export S3_USE_HTTPS=1
export S3_VERIFY_SSL=0

tensorboard --logdir=s3://<path>
