HANA EML Tensorflow integration causing issue, SDA connection error.

179 Views

Hi,

I am trying to setup a HANA EML / Tensorflow, where I have deployed HANA express on one server and TensorFlow (Ubuntu) on another.

I followed all the steps of the SAP academy SAP HANA External Machine Learning guide, and also followed the steps to ensure the TensorFlow integration:

https://www.sap.com/developer/tutorials/mlb-hxe-setup-tensorflow.html

I also downgraded the Tenserflow version to 1.5.0, as 1.8.0 is not supported.

Everything is working on the TensorFlow side, the model is served and working.
On HANA though, the SDA connection keeps giving me an error:

SAP DBTech JDBC: [403]: internal error: Connection failed for remote source TensorFlowModelServer. Reason: not supported

Any idea on what the issue could be?

Br,

Mads
