Tensorboard not working following the documentation.

Following this documentation here.

https://docs.microsoft.com/en-us/azure/machine-learning/how-to-monitor-tensorboard

I have followed all the steps exactly as documented. But whenever I run tb.start() I do get an endpoint URL, but it always gives me a "502 Bad Gateway" error.

I see a similar issue was raised here.

https://github.com/Azure/MachineLearningNotebooks/issues/920

Although the answer wasn't helpful as it just pointed back to the documentation which I was already trying, and failing to get working.

從連結的 Azure Machine Learning TensorBoard 文件開始，將其設定方式與失敗的 tb.start() 呼叫及回傳的 endpoint 進行比較。檢查 issue #920 以了解先前的脈絡，然後依照文件中的步驟重現 502 Bad Gateway 回應。完成的標準是確認責任在於文件還是 Azure ML service path，並記錄經過驗證的可行操作程序，或已縮小範圍的服務缺陷。
