Error running migrate.py script

mschnyde opened this issue 4 years ago · comments

Hi Tanja,

I checked the other issues instructions so I cleaned my grakn keyspace, created a new one but then the migration script gives me this error:

Loading from [./data/person] into Grakn ...

During handling of the above exception, another exception occurred:

Thanks for raising this issue, @amn41 will get back to you about it soon✨

Please also check out the docs and the forum in case your issue was raised there too 🤗

@mschnyde What version of grakn are you using?

mschnyde · Answer 3 · Tue Apr 07 2020 14:32:42 GMT+0800 (China Standard Time)

Hey @tabergma , thank you for the fast reply !

I'm running on rasa 1.7 and grakn-client 1.6 :)

Tanja · Answer 4 · Tue Apr 07 2020 16:23:41 GMT+0800 (China Standard Time)

This repository requires Grakn 1.5.7 (grakn-client. 1.5.3). So I guess they changed something in Grakn 1.6 that lead to the error you are getting. Can you try with Grakn 1.5.7 and grakn-client 1.5.3? Otherwise, you need to update the migration script. This documentation page might help with that: https://dev.grakn.ai/docs/client-api/python

navodjanitha · Answer 5 · Thu Apr 16 2020 19:08:50 GMT+0800 (China Standard Time)

I used the Grakn 1.5.7 and still get the same error.

Tanja · Answer 6 · Fri Apr 17 2020 22:42:52 GMT+0800 (China Standard Time)

I just double checked and the script is working for me. Let's double check the versions.
What do you get if you execute grakn server version? I get the following:

1.5.7

What do you get if you execute pip freeze | grep grakn? I get the following:

grakn-client==1.5.3

I am using Python 3.6.8.

@tabergma I faced the same errors like @mschnyde and I followed the steps you have mentioned.
when I execute grakn server version I get 1.7.1 and
when I execute pip freeze | grep grakn I get grakn-client==1.6.0 grakn-kglib==0.2.1
What would I miss?
I am using Python 3.7.6

Tanja · Answer 8 · Thu Jun 04 2020 15:40:04 GMT+0800 (China Standard Time)

@Wickky The scripts in this repository only work with the versions I mentioned in my comment above (grakn server 1.5.7 and grakn-client 1.5.3). If you want to use a newer version of grakn you need to update the scripts. Otherwise, you need to make sure to use the same grakn versions as I do.

I received a similar error and fixed it.
When I received this error :

`    raise GraknError("Server/network error: {0}\n\n generated from request: {1}".format(e, request))
grakn.exception.GraknError.GraknError: Server/network error: <_Rendezvous of RPC that terminated with:

                                                                     ^

}`

It was because the format for 'opening-date' field in the /data/account.csv file did not match grakn's date formats. opening-date format seems to be:
yyyy-mm-ddThh:mm:ss.ffffff so I changed it to yyyy-mm-ddThh:mm:ss.fff and it worked.

grakn required one of the following formats:
yyyy-mm-dd
yyyy-mm-ddThh:mm
yyyy-mm-ddThh:mm:ss
yyyy-mm-ddThh:mm:ss.f
yyyy-mm-ddThh:mm:ss.ff
yyyy-mm-ddThh:mm:ss.fff

I guess moral of the story, even though it said syntax error, it was most likely a grakn syntax error, check your formats.
