[DISCUSS] Support Python ML Pipeline API
Hi everyone,
FLIP-39[1] rebuilds the Flink ML pipeline on top of TableAPI and introduces
a new set of Java APIs. As Python is widely used in ML areas, providing
Python ML Pipeline APIs for Flink can not only make it easier to write ML
jobs for Python users but also broaden the adoption of Flink ML.
Given this, Jincheng and I discussed offline about the support of Python ML
Pipeline API and drafted a design doc[2]. We'd like to achieve three goals
for supporting Python Pipeline API:
- Add Python pipeline API according to Java pipeline API(we will adapt the
Python pipeline API if Java pipeline API changes).
- Support native Python Transformer/Estimator/Model, i.e., users can write
not only Python Transformer/Estimator/Model wrappers for calling Java ones
but also can write native Python Transformer/Estimator/Models.
- Ease of use. Support keyword arguments when defining parameters.
More details can be found in the design doc and we are looking forward to
your feedback.
Best,
Hequn

Hi Becket,
Thanks a lot for your advice. Definitely agree with you that we should
follow the FLIP process.
Will pay more attention to this next time.
Best, Hequn

I just had an offline chat with Hequn and realized that FLIP-96 has already
been opened for this discussion. I missed that because the FLIP was not
mentioned in the thread.
I am fine with proceeding to a vote.
Thanks,

Hi Hequn,
Given this is an addition to the public API, we probably should follow the
FLIP process. It would be a quick one though, I think.

Hi all,
Thanks a lot for your valuable feedback!
As it seems we have reached a consensus on the discussion now. I have

Re: [DISCUSS] Support Python ML Pipeline API
Posted by Rong Rong <wa...@gmail.com>.
Thanks for driving this initiative @Hequn Cheng <he...@apache.org>.
Moving towards python based ML is definitely a huge win consider how large
the python-ML community is. a big +1 on my side!
Regarding the doc, I only left a few comments on the specific APIs. overall
the architecture looks very good!
Looking forward to it!

Hi everyone,
Thanks a lot for your feedback. I have created the FLIP[1].

Re: [DISCUSS] Support Python ML Pipeline API

Hi Hequn,
Thanks for bringing up the discussion. +1 to this feature. The design LGTM.
It's great that the Python ML users could use both the Java Pipeline
Transformer/Estimator/Model classes and the Python
Pipeline Transformer/Estimator/Model in the same job.
Regards,
Dian

Hi Hequn,
Thanks for bring up this discussion.
+1 for add Python ML Pipeline API, even though the Java pipeline API may
change.
I would like to suggest create a FLIP for this API changes. :)
Best,
Jincheng
