nedlowe / gremlin-python-example Goto Github PK

Add node and Add properties are different statement. What hapens when the property fails to execute?

Node is added without property.

Hi, users are unable to run gremlin-python-example due to dependency conflict with tornado package.
As shown in the following full dependency graph of gremlin-python-example, gremlin-python-example requires tornado，while gremlinpython requires tornado>=4.4.1,<5.0.

According to pip’s “first found wins” installation strategy, tornado==6.0.3 is the actually installed version. However, tornado==6.0.3 does not satisfy tornado>=4.4.1,<5.0.

Dependency tree

Thanks for your help.

Hello, I am very happy that you can open the code. I have a problem now. Now every time I make a query, you have to establish a connection here. Why didn't you release the connection after establishing the connection?

I have followed everything you did in your app.py and I am using chalice too. But somehow, when I try to run my lambda functions, I get this error. I am trying to connect to a Neptune db instance and check if I can create my first vertex.
