“AttributeError: ‘module’ object has no attribute ‘blah'”

  • The obvious cause of this is that the settings.py doesn’t have the directory containing blah listed in INSTALLED_APPS.
  • A less obvious cause: you’ll also get this error if the directory doesn’t contain a file __init__.py.

  1. I’m just having the same error, and either of those do not apply. I have the app listed in INSTALLED_APPS, and I have the __init__.py.

  2. I’m new to the whole python world, but im having this same type of problem:

  3. just a brief note

    if you use import to include a module, make sure you don’t have a file named just the same as the module you are trying to include in current directory

    it seems that python takes preference for local files over modules thus import fails

    a rookie observation

    cheers

  4. Thanks for the hint. In my case the script was named “Cookie”, the same as the module imported. One symptom was that I was getting double printing in both Terminal and browser.

  5. this is my error
    attributeerror ‘module’ object has no attribute system
    affer the compilation
    help me…

  6. thanks. my problem was that i had two versions of a python package (numpy). i was trying to invoke a method that was only in the new one, however it found the old package first, so it couldn’t locate the new method.

    anyway, your post got me looking in the right direction :)

  7. Anyone here know how I can pass a regexp this module?:

    import re

    def htc(m):
    return chr(int(m.group(1),16))

    def urldecode(url):
    rex=re.compile(‘%([0-9a-hA-H][0-9a-hA-H])’,re.M)
    return rex.sub(htc,url)

    if __name__ == ‘__main__':
    print urldecode(‘adasasdasd%20asdasdasdas’)

    Using re.urldecode gives me the same “‘module’ object has no attribute” error but I’m new at this and don’t really know what I’m doing. The module seem to work fine I just can’t figure out how to pass a regexp to urldecode. Example:

    match=re.compile(‘flv_url=(.+?)amp;url_bigthumb’).findall(link)
    urls=re.urldecode(‘match’)

    or

    match=re.compile(‘flv_url=(.+?)amp;url_bigthumb’).findall(link)
    print urldecode(‘match’)

    Thanks for any help.

  8. I am seeing the replies as below
    Thanks so much! __init__.py was my problem…

    Can anyone explain me the problem of __init__.py problem?

  9. im my case i had the _init_.py, but it had some content like this:

    import settings
    try:
    import ldap
    CAN_USE = True
    except:
    CAN_USE = False

    so i removed it and everything is fine now…

  10. I have this wierd kind of error.
    I couldn’t find an answer for this anywhere.

    AttributeError: ‘module’ object has no attribute ‘walk’

    This happened when I tried to execute this command.
    os.chdir(‘H:/Project/’)
    for subdir,dir,files in os.walk(‘H:/Project/’):
    #print subdir
    #print dir
    #print files

    for file in files:
    if file == file_name:

    any help is appreciated !

  11. well thanks snf.
    In my case i had a python file random.py and was trying to import random module. Just deleting the py file really helped.
    Thanks..

  12. For me the problem was old pyc’s all over the place in Mac OS X.

    To double-check a find command on the pyc’s:

    cd /usr/local/lib/python2.7
    find . -type f -name “*.pyc” -exec sudo echo {} \;

    Once you’re happy with the list of files, delete them with:

    /usr/local/lib/python2.7
    find . -type f -name “*.pyc” -exec rm -f {} \;

  13. when i try to import pylab i have the following error
    Traceback (most recent call last):
    File “”, line 1, in
    File “/usr/lib/pymodules/python2.7/pylab.py”, line 1, in
    from matplotlib.pylab import *

    new_class = new.classobj(“%sSubplot” % (axes_class.__name__),
    AttributeError: ‘module’ object has no attribute ‘classobj’

    but if i try to import from the directory /usr/lib/python2.7/ it works fine what can be the possible problem

  14. Can any Body help me with this error.

  16. There are a lot of different reasons,
    and none among mentioned is mine (cyclic import). So to solve the problem, I’ve ran ./manage.py shell –trace
    The –trace option let you see the traceback and catch the reason of the problem!

  17. Thank you for this thread!! I got so frustrated with this problem that I reinstalled my OS twice to try fix it…

    Turns out it was a simple matter of renaming the modules with the same names in the base directory :( :(

    Thanks again – lifesaver @RachelWillmer, and @snf

  18. My problem was having a script named “io.py” in my project directory. After renaming this file, it worked. My error was:

    AttributeError: ‘module’ object has no attribute ‘BufferedIOBase’

  19. I am getting this error:

    I am doing just:

    import sqlanydb

    When compiling it gives this error message:

    Connection
    File “build/bdist.solaris-2.10-i86pc/egg/sqlanydb.py”, line 419, in __init__
    File “build/bdist.solaris-2.10-i86pc/egg/sqlanydb.py”, line 413, in load_library
    sqlanydb.InterfaceError: Could not load dbcapi. Tried: dbcapi.dll,libdbcapi_r.so,libdbcapi_r.dylib
    Exception AttributeError: “‘Root’ object has no attribute ‘api'” in <bound method Root.__del__ of > ignored

    Can anyone help?

  20. Thanks for this.. I learned this about modules awhile ago, but rarely am I writing my own modules in Python. Maybe there is room for improvement in the stack trace error with this one?

    This –> “A less obvious cause: you’ll also get this error if the directory doesn’t contain a file __init__.py.”
