The following code gives me an error
from django.db import connection
cursor = connection.cursor()
Error message:
Undefined variable from import: cursor
I have Django 1.2.5 installed. How can a resolve this issue?
Thanks
This was just a PyDev information message as Daniel pointed out. I am able to run the script without modifying anything.

Who can tell me why the method of Selenium WebDriver.WaitDisplayed is not working in my code below?
I can share other code if needed?
Set a = webdriber.FindElementsByClass("search-global-typeahead__collapsed-search-button")
a.Item(1).WaitDisplayed(True).Click ' operation timed out after -1ms. Run-time err'21'
a.Item(1).Click ' gives an error
I added code below; without successful result
a.Item(1).WaitDisplayed(True, 100).Until(a.Item(1).IsDisplayed,10)
I guess to start with the most obvious, does it still cause an error after fixing the typo in the 'webdriber' identifier? I'm guessing your declaration is spelled 'webdriver'.
I am failing to use readNetFromDarknet function for the reasons I do not understand. I am trying to use yolo3-spp with this configuration file https://github.com/pjreddie/darknet/blob/master/cfg/yolov3-spp.cfg.
import cv2
net = cv2.dnn.readNetFromDarknet("../models/yolov3-spp.weights", "../models/yolov3-spp.cfg")
However, this gives me the following error:
error: OpenCV(4.5.4) /tmp/pip-req-build-3129w7z7/opencv/modules/dnn/src/darknet/darknet_io.cpp:660: error: (-215:Assertion failed) separator_index < line.size() in function 'ReadDarknetFromCfgStream
Interestingly, if I use readNet instead of readNetFromDarknet, it seems to work just fine. Should I stick to using readNet instead and why readNetFromDarknet is not actually working?
Your problem in order function arguments. readNetFromDarknet waits first config file and second - weights. A readNet function can swap arguments if they have a wrong order.
So right code:
net = cv2.dnn.readNetFromDarknet("../models/yolov3-spp.cfg", "../models/yolov3-spp.weights")
I created angular 6 application(Using node). In this application I used vega-embed. It is giving me compilation error.
import embed from 'vega-embed';
I also changed code in util.d.ts import stableStringify = require('json-stable-stringify') but giving following error
ERROR in node_modules/vega-lite/build/src/util.d.ts(58,41): error TS2304: Cannot find name 'Extract'.
node_modules/vega-lite/build/src/util.d.ts(73,58): error TS2304: Cannot find name 'Exclude'.
Please suggest.
I've been using pyodbc and free TDS to a submit queries to a microsoft SQL-2012 without issue for a while now but have recently stumbled on an issue.
When I submit a longer query I get an error message saying that one of the identifiers is too long and the script crashes.
The EXACT same query works in management studio and doesn't even return a warning.
I've added the following to my code with no avail.
SET QUOTED_IDENTIFIER OFF
SET ANSI_NULLS ON
The piece of code that the error is referring to is here:
(ZR_KOPF.ZRK_DDP_B IN ('190/TEMP.AA1H', '190/RAIN.AA1H', '190/WDR.AA1H', '190/WSP.AA1H', '190/SD1.AA1H', '190/HUMID.AA1H', '190/NO2.AA1H', '190/PM10.AA1H', '190/PM2.5.AA1H', '190/SO2.AA1H', '190/OZONE.AA1H', '190/CO.AA1H', '206/TEMP.AA1H', '206/RAIN.AA1H', '206/WDR.AA1H', '206/WSP.AA1H', '206/SD1.AA1H', '206/HUMID.AA1H', '206/NO2.AA1H', '206/PM10.AA1H', '206/PM2.5.AA1H', '206/SO2.AA1H', '206/OZONE.AA1H', '206/CO.AA1H')) AND ZR_KOPF.ZRK_BASEPRODUCTION = 1)
The error I get is:
pyodbc.ProgrammingError: ('42000', "[42000] [FreeTDS][SQL Server]The identifier that starts with ''190/TEMP.AA1H', '190/RAIN.AA1H', '190/WDR.AA1H', '190/WSP.AA1H', '190/SD1.AA1H', '190/HUMID.AA1H', '190/NO2.AA1H', '190/PM10.AA' is too long. Maximum length is 128. (103) (SQLExecDirectW)")
Pyodbc version: 4.0.18b1
freetds version: 1.00.48
Any help would be much appreciated
Cheers!
So turns out the spaces between each of the items in the list made all the difference...
I removed them and the query worked without a hitch.
Thanks for all the help everyone!
I am using kibi-community-demo-full-4.6.4-linux-x64 version.
In datasource:
"connection_string": "jdbc:hive://localhost:10000/root",
"libpath": "/home/pare/Downloads/jar/",
"drivername": "org.apache.hadoop.hive.jdbc.HiveDriver",
"libs": "hive-jdbc-0.11.0.jar,hive-metastore-0.11.0.jar,libthrift-0.9.1.jar,hive-service-0.13.1.jar,hive-jdbc-1.2.1.2.3.2.0-2950-standalone.jar,hadoop-common-2.7.1.2.3.2.0-2950.jar",
After that when in queries I write a query it will show error like:
Queries Editor: Error 400 Bad Request: Error running static method java.lang.IllegalArgumentException: Bad URL format at org.apache.hive.jdbc.Utils.parseURL(Utils.java:185) at org.apache.hive.jdbc.HiveConnection.(HiveConnection.java:84)
What is the error can any one explain me how to solve it?
I am able to connect after changing the jars version.
and also I changed the driver name "org.apache.hive.jdbc.HiveDriver".
