Greeetings,
per instructions for IPython, I am supposed to be able to run this import when coding:
from IPython.lib.security import passwd_check
I have IPython 8.8.0 installed as part of a jupyter install.
however, when I attempt to run this library, it reports:
ModuleNotFoundError: No module named 'IPython.lib.security'
what am I missing?
THanks
It looks to me that the IPython.lib.security is not present anymore in version 8.x.
If you are using version 7x you should be able to import it with.
I was able to import successfully:
from IPython.lib.security import passwd_check
on my 7.x version
IPython.__version__
'7.25.0'
if you want to lower version you can try:
%pip install IPython==7.25.0
I am working at blender script, where I want to use YAML. So I try to import it:
from pydantic import BaseModel
from pydantic_yaml import YamlModel
But when I run my script, this error will occure:
ImportError: cannot import name 'YamlModel' from 'pydantic_yaml' (C:\Program Files\Blender Foundation\Blender 3.0\3.0\python\lib\site-packages\pydantic_yaml\__init__.py)
I have installed pydantic and pydantic_yaml on both Pythons (Blender one and the common one), if they wouldn't be installed, there would be different error. I tried googling, but google had very few results for this problem. Also, when I open that __init__.py file, there is clearly YamlModel. Thank you for any kind of help.
I found the same error and it is related how pydantic-yaml got installed.
There is a bug in the package. you need to install optional dependencies as well (so called extras).
pip install pedantic-yaml[pyyaml,ruamel]
or manually install pyyaml ruamel please make sure that that Taumel version is <=0.18
I have a question that I assume has a simple answer, but for some reason I am struggling to find it on my own. I have created and activated a virtual environment with virtualenv, and I am trying to install all the necessary packages in order to create a requirements.txt file.
I have, for example, a Python file that begins like this:
import xml.etree.ElementTree as ET
from lib.project import Projector
from lib import writer
import os
import datetime
from datetime import timedelta
from datetime import datetime
import pprint
When I try to run this file from the virtual machine, I receive the following error:
Traceback (most recent call last):
File "readMap.py", line 2, in <module>
from lib.project import Projector
ModuleNotFoundError: No module named 'lib.project'
My problem is that I'm not sure why the virtual environment can't find project.py. My directory structure is:
regiaoSul
lib
__init__.py
arrival_conversion.py
coord_conversion.py
message_conversion.py
project.py
route_conversion.py
stop_conversion.py
wkt_parser.py
writer.py
readMap.py
json_generator.py
The import on line 2 implies lib is a module rather than "a simple repository".
I will try running the script with the flag -m. Something like this -
python -m script_name
make sure to drop the .py extension when you run with -m flag.
Another advice: you don't need to install python files to the virtual environment, they are not some external libraries. They only need to be present (with the same order of packaging) when you run your script.
Thanks to everyone who responded. I believe the issue was some sort of dependency problem. In readMap.py I had imported writer from lib, and in writer.py I had imported Projector from project. I moved the function that required Projector from writer.py to readMap.py and it worked.
I still don't fully understand why this was a problem. Until recently I had been running my scripts in PyCharm and they all worked with the structure I had. It was only when I tried to run them from the command line in my virtual machine that they didn't work.
If anybody would like to explain the distinction to me and what the exact problem was with my imports, feel free to.
I sometimes face the same issue. A solution is to add the path to sys.path by:
import sys
sys.path.insert(0, "/path/to/your/package_or_module")
When I want to import SkipWrapper It occurs an error
from gym.wrappers import SkipWrapper
ImportError: cannot import name 'SkipWrapper' from 'gym.wrappers'
I can't find any solution on the internet. I tried to downgrade gym to 0.9.5 but It also doesn't work.
Try this import
from gym.wrappers.frame_skipping import SkipWrapper
OR
Downgrade/upgrade the gym package. Source Code installed should contain the SkipWrapper class definition.
https://programtalk.com/vs2/?source=python/9609/gym/gym/wrappers/frame_skipping.py
'Monitor' has been removed from 'gym.wrappers' in gym0.23.
Running in the gym0.21, it is successful.
At some point in the last few days, Matplotlib stopped working for me on OS X. Here's the error I get when trying to import matplotlib:
Traceback (most recent call last):
File "/my/path/to/script/my_script.py", line 15, in <module>
import matplotlib.pyplot as plt
File "/Library/Python/2.7/site-packages/matplotlib/pyplot.py", line 34, in <module>

from six.moves import _thread
ImportError: cannot import name _thread
The only system change I can think of was the Apple-forced NTP update and maybe some permission changes I did in /usr/local to get Brew working again.
I tried reinstalling both Matplotlib and Python-dateutil via Pip, but this did not help. Also tried a reboot. I'm running Python 2.7.6, which is located in /usr/bin/python. I'm running Yosemite (OS X 10.10.1).
sudo pip uninstall python-dateutil
sudo pip install python-dateutil==2.2
I had the same error message this afternoon as well, although I did recently upgrade to Yosemite. I'm not totally sure I understand why reverting dateutil to a previous version works for me, but since running the above I'm having no trouble (I generally use pyplot inline in an ipython notebook).
This problem is fixed in the latest six and dateutil versions. However, in OS X, even if you update your six to the latest version, you might not actually update it correctly. This is what happened to me:
After doing a pip2 install six -U, the new six module was installed in /Library/Python/2.7/site-packages/. However, when I loaded six in a python 2.7 terminal, and checked its path, this is what I got:
import six
print six.__file__
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six.pyc
So, python was using an old version of six, which I removed by typing:
rm -rf /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six.*
This fixed this issue for me.
Installing the python-dateutil==2.2 did not work for me.
But a quick-and-dirty workaround did work! I replace six.py in python 2.7 with the six.py from python 3.4 (virtualenv). Since, I have the problem in 2.7 but not 3.4.
UPDATE
I had the same problem again after reinstalling python (and after upgrading to El Capitan). Un-obvious thing is that this error occurs only in the IPython shell and notebook (when I do import matplotlib.pyplot as plt) but works fine from a Python shell.
So a better solution (that did work in my case) without a dirty work-around is to force install both six and ipython. Here is what I did to have this fixed :
$ pip install --ignore-installed six
$ pip install --ignore-installed ipython
It is possible that you have a perfectly installed version of any packages you have installed, but the version used by default is not the one you want. You can see the list of paths that python search from in order to find its packages as follows:
>>> import sys
>>> sys.path
In order to let python search first the most updated version of certain package, instead of removing the system version, what can be done is to set the system variable PYTHONPATH in the ~/.bash_profile (or ~/.bashrc if linux) config file to the path where the new packages are installed:
export PYTHONPATH=/Library/Python/2.7/site-packages
An alternative is to modify the python path inside your python script by adding the path at the beginning of the path list:
import sys
sys.path.insert(1,'/Library/Python/2.7/site-packages')
This needs to be done for every script you need a certain package version. You might want for some reason use an older version that you have installed.
BTW all my installations with easy_install, or pip, or from sources go to /Library/Python/2.7/site-packages
This worked en EL Capitan, and now also in macOS Sierra (10.12.2)
