Using redis and following the tutorials from http://nullege.com/codes/search/redis.Redis.send_command
When trying this example:
results = r.send_command(
'ZRANGEBYSCORE %s 0 %s LIMIT 0 %s\r\n' % (
qk,
ts,
limit
In my case i am getting:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'Redis' object has no attribute 'send_command'
And redis.Redis hasnt method send_command(). This is a method of the Connection class.

help me please what can i do
I want to print namespaces for my ecs-client. When I am using print(client.user_info.whoami()) I am getting the output. But when I am executing the below code I am getting attribute error.
from ecsclient.client import Client
from ecsclient.common.multitenancy import namespace
client = Client('3',
username='root',
password='password',
token_endpoint='https://abc.xyz.com:4443/login',
ecs_endpoint='https://abc.xyz.com:4443')
print(client.namespace.get_namespaces())
Error:
Traceback (most recent call last):
File "test.py", line 12, in <module>
print(client.namespace.get_namespaces())
AttributeError: 'Namespace' object has no attribute 'get_namespaces'
instead of using print(client.namespace.get_namespaces()) I used print(client.namespace.list()) and got the list of namespaces
I am trying to open and load pickle file but by two ways. But every time I am getting an error.
Request you to please help.
First way :
enron_data = pickle.load(open("D:/New/ud120-projects/final_project/final_project_dataset.pkl", "r"))
Error: Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: a bytes-like object is required, not 'str'
Second Way :
enron_data = pickle.load(open("D:/New/ud120-projects/final_project/final_project_dataset.pkl", "rb"))
Error : Traceback (most recent call last):
File "<stdin>", line 1, in <module>
_pickle.UnpicklingError: the STRING opcode argument must be quoted

If you are on Windows you have to use a raw string and backslashes like this:
r'D:\path\to\your\file'
I have the following code:
s = Search(using=Elasticsearch('http://user:passwd#ipaddress'), index="myindex")
q = Q("multi_match", query='some query', fields=['_all'])
s = s.query(q)
response = s.execute()
print('Total %d hits found.' % response.hits.total)
for hit in response:
print(hit.title)
And I get the error:
Traceback (most recent call last):
File "/usr/local/lib/python3.5/dist-packages/elasticsearch_dsl/utils.py", line 102, in __getattr__
return _wrap(self._d_[attr_name])
KeyError: 'title'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "FindImage.py", line 89, in <module>
main(args.image_file)
File "FindImage.py", line 82, in main
query_db([1], [2])
File "FindImage.py", line 77, in query_db
print(hit.title)
File "/usr/local/lib/python3.5/dist-packages/elasticsearch_dsl/utils.py", line 105, in __getattr__
'%r object has no attribute %r' % (self.__class__.__name__, attr_name))
AttributeError: 'Result' object has no attribute 'title'
However that is in direct contradiction to what the docs state:
Docs
What am I doing wrong? How can I correctly extract the hits and my values from the response?
EDIT
Also the response object ist supposed to have a method "toDict" but when I try to call it I again get an AttributeError.
For the "toDict" question, response.to_dict() works for me. Not sure if this behaviour is the same across lib versions.
Apparently the ".title" references an actual column in their example.
When I used hit.doc.FIRSTTAG, FIRSTTAG being a column in MY NoSQL-db it worked.
Still does not explain the missing method, but I am happy with it for now.
So to anyone having the same problem:
Use your own columns names when evaluating the response object e.g. in my example:
for hit in response:
print(hit.doc.FIRSTTAG)
I'm trying to use PyKDE, PyKDE.kdecore.KStandardDirs to be precise. This method is called with two strings according to the documentation and according to the PyQt4 documentation, I can use standard Python strs instead of QString.
This doesn't work:
>> KStandardDirs.locate()("socket", "foo")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: KStandardDirs.locate(): not enough arguments
>>> KStandardDirs.locate("socket", "foo")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: KStandardDirs.locate(): argument 1 has unexpected type 'str'
I can't use QString either because it doesn't seem to exist:
>>> from PyQt4.QtCore import QString
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name QString
>>> from PyQt4.QtCore import *
>>> QString
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'QString' is not defined
What am I doing wrong?
I suspect that PyKDE is not yet Python 3 ready, at least as far as that error message is concerned; try passing in a bytestring instead:
KStandardDirs.locate(b"socket", "foo")
