Pydgraph failure

Users

Hi,

I have spent two days to study Dgraph and it seems quite interesting and promising database. The TOUR and curl examples helped a lot to understand Dgraph. I am testing it for our company new projects. But I failed in the first in the first phase, installing the client (pydgraph). In our company, python and scala are main language and I am not familiar with GO, I tried to copy & paste go code to run simple tests, but not succeed.

Are there plans to continue maintaining and developing pydgraph package?
The commands I used were:

git clone https://github.com/dgraph-io/pydgraph
cd pydgraph
python setup.py test (Failed)

The tests were failed.

The dgraph-io/pydgraph client hasn’t been updated in a while. The community has been working on a client which works with v1.0.0 and above.

https://github.com/kochhar/pydgraph/tree/kochhar/v0.9.4+

We’ll get this merged into dgraph-io/pydgraph soon but in the meantime give this a try.
