Python client - SyntaxError

[Sharathmk99]

Hi,

I'm using python3
python3 --version
Python 3.5.2

I installed seldon-core using
pip3 install seldon-core

When i try using seldon-core-tester, i'm getting SyntaxError. Please find below complete error,
Traceback (most recent call last): File "/home/seldon/.local/bin/seldon-core-tester", line 7, in <module> from seldon_core.microservice_tester import main File "/home/seldon/.local/lib/python3.5/site-packages/seldon_core/microservice_tester.py", line 60 raise SeldonTesterException(f"Unknown dtype in reconciliate_cont_type {dtype}") ^ SyntaxError: invalid syntax seldon@mlseldon:~/seldon-test$ python3 /home/seldon/.local/lib/python3.5/site-packages/seldon_core/microservice_tester.py File "/home/seldon/.local/lib/python3.5/site-packages/seldon_core/microservice_tester.py", line 60 raise SeldonTesterException(f"Unknown dtype in reconciliate_cont_type {dtype}") ^ SyntaxError: invalid syntax

What is the full command you're calling including all arguments? Also do you have the latest version of the pip package (0.2.7)?

[Sharathmk99]

I checked the version of pip its,
pip 19.1.1

[jklaise]

Sorry, I meant the seldon_core package from pip. Also it would be helpful to have the full command with arguments to see why it failed.

[Sharathmk99]

Yes its 0.2.7
seldon-core 0.2.7

[jklaise]

What is the full command you used?

@arun-muthy @Sharathmk99 looks like you haven't set the correct dtype in the contract.json, it has to be one of FLOAT or INT, if you're trying to test string or binary data it won't work:

seldon-core/python/seldon_core/microservice_tester.py

Lines 55 to 60 in c62dbfa

	if dtype == "FLOAT":
	return feature
	elif dtype == "INT":
	return (feature + 0.5).astype(int).astype(float)
	else:
	raise SeldonTesterException(f"Unknown dtype in reconciliate_cont_type {dtype}")

@jklaise thanks for that.. i'll see what i'm working with

[ghost]

still no luck, i'm going through examples provided by seldon, here's the json: https://github.com/SeldonIO/seldon-core/blob/master/examples/models/sklearn_iris/contract.json
