>>> import allennlp
>>> from allennlp.common.util import sanitize
Traceback (most recent call last):

ModuleNotFoundError: No module named 'allennlp.common'
My allennlp version is 0.2.1 and even trying to update to 0.4.1 it gives the same error.
TIA
Do check python version, Allennlp keeps pushing updates on regular period and thing works according to Python as well as Pytorch version.

I keep getting a ModuleNotFoundError when trying to import SQLAlchemy in the interpreter.

I tried uninstalling SQLAlchemy, deactivating the virtual environment, reactivating the virtual environment, and upgrading pip. This did nothing. I still have the same error.
As I understand it for historical reasons the distribution name, ie. on PyPi, is not always the same as the import name. Confusing but the way it is. This doesn't just affect SQLAlchemy but a lot of libraries have this issue.
$ ve/bin/pip install SQLAlchemy

It's case sensitive just use sqlalchemywith lowercase.

After following the Ubuntu/Debian installation instructions for the Nest simulator I can only import the nest module in python2.x, not python3.x
$ python3

The default install compiles with the default Python version which is still 2 in Ubuntu.
To use Python 3, run:
cmake -Dwith-python=3 -DCMAKE_INSTALL_PREFIX:PATH=</install/path> </path/to/NEST/src>
Mentioned here in the doc.
NB: don't forget to clear the build folder to avoid issues
When trying to install pgadmin4 in desktop mode on my Ubuntu system, I received a ModuleNotFoundError for _ctypes.
I did some research and found that _ctypes requires the libffi-dev package to be installed. However it seems that libffi-dev and thus _ctypes was installed for Python 2.7, when I run import ctypes it seems to work:
$ python2
Python 2.7.15+ (default, Nov 27 2018, 23:36:35)
[GCC 7.3.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import ctypes
>>>
When I try to do the same for Python 3.7, it doesn't work:
$ python
Python 3.7.3 (default, Jun 21 2019, 12:46:58)
[GCC 7.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import ctypes
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python3.7/ctypes/__init__.py", line 7, in <module>
from _ctypes import Union, Structure, Array
ModuleNotFoundError: No module named '_ctypes'
How could I add the module _ctypes to my Python 3.7 configuration?
If you install python from source file, you have to install some required packages manually as mentioned in https://superuser.com/questions/1412975/how-to-build-and-install-python-3-7-x-from-source-on-debian-9-8.
Actually you are supposed to see some errors after make due to libffinot found as shown in the screenshot below. However, you can still run make install despite the error. When you open python after the installation and import the module, it then gives you such error.
To solve this problem, you can install the dependent package i.e libffi or libffi-devel(redhat) prior to ./configure, make and make install as mentioned in:
Package libffi was not found in the pkg-config search path REDHAT6.5 and

I have installed graph-tool:
brew --prefix graph-tool
'/usr/local/opt/graph-tool
but when trying to import it:
Python 3.6.4 |Anaconda, Inc.| (default, Jan 16 2018, 12:04:33)
[GCC 4.2.1 Compatible Clang 4.0.1 (tags/RELEASE_401/final)] on darwin

>>> from graph_tool.all import *
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'graph_tool'
:(
Does anyone have a solution for this?
Thanks
Homebrew installs the library using its own Python interpreter, which has its module path somewhere in /usr/local/opt/. You are using the anaconda Python interpreter, which knows nothing about homebrew-installed modules. The solution here is simply to use homebrew's Python interpreter, not anaconda's.
So the issue is that apparently Django uses the sqlite3 that is included with python, I have sqlite3 on my computer and it works fine on its own. I have tried many things to fix this and have not found a solution yet.
Please let me know how I can fix this issue so that I can use Django on my computer.

I figured out that this error was caused by me changing my python path to 3.5 from the default of 2.7.
