不太清楚问题出在了哪里，谢谢~

@maweijiao Hi, I am facing the same issue. Pls let me know if you have any update on this. Thanks

@maweijiao @hungbui-io I guess the two lines is enough:

%ngql MATCH (p:entity)-[e:relationship]->(m:entity) WHERE p.entity.name == '迈克尔·鲁克' RETURN p,e,m
%ng_draw

No need to config anything

Sorry I missed this issue.

The ngdraw command can be done only after the query being done, a 'df=' call will interrupt the context needed for ng_draw.

Could you do ng_draw follow the ngql one by one? This should work.

The df = _ could be evaluated with another ngql call.

We can add feature to draw from a df later to improve this later.

[wey-gu]

Also, now ng_draw will be working with both result formats in latest release.

Hi @wey-gu . I am still facing the issue...Any idea?

Dear @hungbui-io

Would you mind helping perform pip install -U this package to see how it goes with latest version?

As from your backtrack, it's shown with an older version and in the current release, I make it try to cast other styles of output into pd df.

[maweijiao]

The original version of my installation package was 0.12.4. After I upgraded this installation package, it still reported an error if I did not set “IPythonNGQL.ngql_result_style=“pandas””. After setting it, it can be displayed normally.

After setting it, it can be displayed normally.

Hi @wey-gu, thanks for your support. I have updated the package to 0.13.1, and here is the new error. [ERROR]: the last execution result is not a %ngql query, make a query first or use %ng_draw <some query> instead, please. Something wrong with the result parsing: { "Nodes": [ "Access key", "Anonymized completely", "Access key value", "Auto-populates in anonymized format - *****", "In anonymized format", "Actian avalanche", "Inputs according to actian's connection support", "Data warehouse", "Action", "View details and delete", "Delete button", "Edit button", "Action column", "Right side", "Publish icon", "Re-run button", "Actions column", "Edit", "Add", "Adding filled details", "Add button", "Particular rule detail and display it in a table below", ... "Heading": "" } Error: 'Network' object has no attribute 'keys'

Dear @hungbui-io @maweijiao ,

The latest release I just made 0.13.2 should fix the above issues:

• Now it renders raw style result set in last cell
• Now it renders when ng_draw was run twice in a row

Kindly help verify your use case when possible, thanks!!

[maweijiao]

@wey-gu Thanks！When I upgraded, there was an error, regardless of whether I set ‘IPythonNGQL.ngql_result_style=“pandas”’.

[wey-gu]

@maweijiao thanks a lot for the test! Could you please help share what queries are you using to trigger such error? And/or any queries will end up such error? As I cannot reproduce it in my env.

[wey-gu]

@maweijiao I had tried different types of queries and render with %ng_draw, all run perfectly.

%ngql GET SUBGRAPH 2 STEPS WITH PROP FROM "p_0" YIELD VERTICES AS nodes, EDGES AS relationships;

%%ngql
MATCH path_0=(n)--() WHERE id(n) == "p_0"
OPTIONAL MATCH path_1=(n)--()--()
RETURN path_0, path_1

%%ngql
MATCH (n)-[e]-(m) WHERE id(n) == "p_0"
OPTIONAL MATCH (n)-[e1]-(a)-[e2]-(b)
RETURN n,m,e,e1,e2,a,b

%ngql FIND ALL PATH WITH PROP FROM "p_5703" TO "p_5742" OVER * BIDIRECT YIELD path AS p;
