[sdk] dependency conflict with tensorflow 2.6.0 and seldon-core

[juliusvonkohout]

Environment

• KFP version: 1.7

• KFP SDK version: 1.8.3

• All dependencies version:

[~]$ pip list | grep kfp
kfp                               1.8.3
kfp-pipeline-spec                 0.1.11
kfp-server-api                    1.7.0

kfp==1.8.3 collides with tensorflow==2.6 because it requires

pipelines/sdk/python/setup.py

Line 56 in 220d79d

'typing-extensions>=3.10.0.2,<4;python_version<"3.9"',

while tensorflow needs

Warning!!! Possibly conflicting dependencies found:
* tensorflow==2.6.0
 - typing-extensions [required: ~=3.7.4, installed: 3.10.0.2]

https://github.com/tensorflow/tensorflow/blob/421fba8888bb8f8724bc2e35ca2fdcde16e1bfe5/tensorflow/tools/pip_package/setup.py#L90

is 'typing-extensions>=3.7.4,<4;python_version<"3.9"' not enough?

The same goes for seldon-core==1.11.* and package click and absl-py

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
kfp 1.8.2 requires absl-py<=0.11,>=0.9, but you have absl-py 0.13.0 which is incompatible.
kfp 1.8.2 requires click<8,>=7.1.1, but you have click 8.0.1 which is incompatible.
kfp 1.8.2 requires typing-extensions<4,>=3.10.0.2, but you have typing-extensions 3.7.4.3 which is incompatible.

@chensun click<9,>=7.1.1 works for me with kfp and seldon-core
