import ldap3 error File "<stdin>", line 1, in <module> File "/usr/local/lib/python3.9/dist-packages/ldap3/__init__.py", line 255, in <module>

I have installed ldap3 module for my python3. When I try to run import ldap3, I get such error. Can someone please advice me what to do?

Python: importing from somewhere else?

bash-4.1$ airflow initdb
Traceback (most recent call last):
File "/u/bin/airflow", line 4, in <module>
from airflow import configuration

from dateutil.relativedelta import relativedelta
File "build/bdist.linux-x86_64/egg/dateutil/relativedelta.py", line 5, in <module>
ImportError: cannot import name integer_types
But no issues in interpreter:
bash-4.1$ /u/bin/python2.7

>>> import croniter
>>>
I am assuming it has to do something with:
File "build/bdist.linux-x86_64/egg/dateutil/relativedelta.py", line 5, in <module>
So in interpreter it Is using dateutil from /u/lib/python2.7 whereas in airflow it's using datutil from build/bdist.linux-x86_64/egg/dateutil??
I don't even know where build/bdist.linux-x86_64/egg/dateutil is.
Can someone tell me what's going on and how to tell airflow to import from correct dateutil?

You need to install Six python package.
Just make a pip install six

Cannot import PYMC

When I try to import PYMC installed with pip, enpgk or the canopy GUI package manager, I tried all of them and without success.

I tried to install GFORTRAN with :
~$ sudo apt-get install gfortran-4.6
but I still get the same error.
(there are other questions very similar indeed, but usually the answer has to do with Anaconda and I'm using Canopy)
Any idea of what is going on ? I can import other packages.

Occasional error of import matplotlib

In a newly created terminal, I can import matplotlib with no error. After working for some time in the terminal, however, the following happens:

What's wrong?

With the help of #CaptainMurphy and #IronManMark20, I discovered new.py and new.pyc under ~/temp, which shadows some matplotlib files. After removing them, the problem is solved.

ImportError with pythons libghmm library

I have followed the installation directions to install the GHMM library. However, I still get the following error:

ImportError: libghmm.so.1: cannot open shared object file: No such file or directory
I tried to change my LD_PRELOAD_PATH variable to /usr/local/lib to no avail.
Also, when I try to locate libghmm, I get the following, so the libraries are definitely there:
% locate libghmm
/usr/local/lib/libghmm.a
/usr/local/lib/libghmm.la
/usr/local/lib/libghmm.so
/usr/local/lib/libghmm.so.1
/usr/local/lib/libghmm.so.1.0.0
Any ideas?
