AttributeError: 'module' object has no attribute 'connect'

I have tried to setup the recoll-webui on a CentOS 6.x server with python 2.6.6 installed and each time I am executing a search query through the WSCGI interface I get:

Hi,

This looks like a version mismatch. What Recoll version are you using ?

[patvdv]

Recoll v1.19.4

[ghost]

This should be ok (I just installed 1.19.4 on a clean ubuntu machine, and it works with the current webui code without a fuss).

Do you have the same problem with a non WSCGI run by the way (using webui-standalone.py) ?

I wonder if you might have several copies of the Python module. Maybe you could search for recoll under /usr/lib and /usr/local/lib:

find /usr/lib/python* /usr/local/lib/python* | grep -i recoll

For reference, a 1.19 recoll module install should look like the following (replacing 2.7 with 2.6 of course, and possibly /usr with /usr/local):

find /usr/lib/python* /usr/local/lib/python* | grep -i recoll
/usr/lib/python2.7/dist-packages/Recoll-1.0.egg-info
/usr/lib/python2.7/dist-packages/recoll
/usr/lib/python2.7/dist-packages/recoll/__init__.py
/usr/lib/python2.7/dist-packages/recoll/rclextract.so
/usr/lib/python2.7/dist-packages/recoll/recoll.so

[patvdv]

Hi Jean-François,

Same problem with the standalone version of the webui. This is the result of the find on my machine (with lib64):

/usr/lib64/python2.6/site-packages/recoll
/usr/lib64/python2.6/site-packages/recoll/recoll.so
/usr/lib64/python2.6/site-packages/recoll/__init__.pyc
/usr/lib64/python2.6/site-packages/recoll/__init__.py
/usr/lib64/python2.6/site-packages/recoll/__init__.pyo
/usr/lib64/python2.6/site-packages/recoll/rclextract.so
/usr/lib64/python2.6/site-packages/Recoll-1.0-py2.6.egg-info

What happens if you start python and type:

from recoll import recoll recoll.connect()

[patvdv]

Looks fine I think:

Python 2.6.6 (r266:84292, Jul 23 2015, 15:22:56) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-11)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from recoll import recoll
>>> recoll.connect()
<recoll.Db object at 0x7f89abaad0d8>
>>> 

[ghost]

Yes, this looks normal. This is weird. Groping in the dark...

Are several versions of Python installed on the system ?

Does it still work if you paste the whole top of webui.py into python and add the connect() call ? You need to do it while inside the webui directory (so that the bottle etc. modules are found):

import os
import bottle
import time
import sys
import datetime
import glob
import hashlib
import json
import csv
import StringIO
import ConfigParser
import string
import shlex
import urllib

try:
    from recoll import recoll
    from recoll import rclextract
    hasrclextract = True
except:
    import recoll
    hasrclextract = False

try:
    from recoll import rclconfig
except:
    import rclconfig

recoll.connect()

[patvdv]

Actually it does not then, I am getting the error back:

python 2.6.6 is the only installed version AFAIK

[ghost]

One possible culprit which we left aside is rclextract. Can you please try just:

from recoll import recoll
from recoll import rclextract
recoll.connect()

[patvdv]

This what I get:

At least an explanation why this is not working. Then for looking for a fix, where does the Recoll Python module comes from ?

[patvdv]

Unfortunately I have no centos6 installation around, so I can't be sure, but it seems likely that there is a problem with the recoll-python package.

I tried to build and and install python-recoll with python2.6 (on Debian wheezy), and the webui works just fine (Python 2.6 needs the argparse module to run the webui, but I guess that you already installed this).

So it seems likely that your best bet would be to build recoll from source.

[patvdv]

Hi Jean-François,

I will not go down the route of compiling from source. For the moment I will stick to recoll desktop & CLI. But thank you for extensive help anyway :+1:

[koniu]

CentOS pkg issue? Hopefully rectified upstream. Feel free to reopen if needed.

Hello,

I got the same error on Recoll version1.23.2, under Arch Linux.

The python lib had been installed for Python3, but the WebUI wants Python2 I think.

Although after compiling the python module for python2, I still had the error :

ImportError: librecoll-1.23.2.so: cannot open shared object file: No such file or directory

Which I "fixed" by linking /usr/lib/recoll/librecoll-1.23.2 to /usr/lib/librecoll-1.23.2

After that, the WebUI worked like a charm.
