I am working on widows10 with python3.7
I have downloaded opencv and numpy and sklearn(scikit-learn) and they are in C:\Python37\Lib\site-packages (where pip put them) and when I run
import sys
print(sys.path)
I get the output:
['', 'C:\\Python35\\Lib', 'C:\\Python35\\DLLs', 'C:\\Python35\\Lib\\site-packages', 'C:\\Users\\E6440', 'C:\\Python37\\python37.zip', 'C:\\Python37\\DLLs', 'C:\\Python37\\lib', 'C:\\Python37', 'C:\\Python37\\lib\\site-packages']
on cmd it says C:\Python37\Lib\site-packages which is one of the paths it looks in for when importing but then as soon as I run some code it gives a no module named ___ error
this is similar to the question python cant find module in sys.path but the comments in that one did not help me
edit
solved by using PYTHONPATH that was accurate to the python version
The package you're trying to import the module from may be available in the Python 3.5 installation too, but the package for Python 3.5 may be missing the module you're trying to import. Try moving the Python 3.7 paths ahead of the Python 3.5 paths in your PYTHONPATH environment variable.

I was able to install xgboost on my mac and have it so that I can import the module without any errors. However I cannot use it. When I try to import XGBRegressor. I get the following error :
cannot import name 'XGBRegressor' from 'xgboost' (unknown location).
Some of the support for this type of problem says that there may be more than one xgboost location, and that python is selecting the incorrect xgboost, however I have not been able to find how to fix this problem.
When I print the xgboost.__file__ location, it returns 'None'. However I know its in the site-packages folder in my python path.
I have python 3.9
Maybe this.
conda install -c conda-forge xgboost=0.6a2
Then, restart Spyder and re-run!
So basically I am using PyCharm with Anaconda env Python 3.6. I tried reinstalling everything, folder with my projects env contains the whole package for opencv, in Anaconda Navigator also and PyCharm recognises cv2 when I import (code) yet when i start my main.py it says that there is no cv2 module.
Anyone any ideas why the error occurs?
I suppose the first thing you should check is if your conda environment is configured to your project when you're using PyCharm. Have a look at this: https://docs.anaconda.com/anaconda/user-guide/tasks/pycharm/#:~:text=Configuring%20a%20conda%20environment%20in%20PyCharm,-In%20the%20Settings&text=Select%20Preferences.,dialog%20box%2C%20select%20Conda%20Environment.
I have installed the latest version of IBM SPSS Statistics(Version 26) which has pre installed python 3.4 and 2.7. i am trying to use version 3.4 python. i am able to import modules like pip , sys , os etc. i tried pandas the same way. i am unable to do so. getting error no module found. Hence going through our forum and IBM support did the following changes.
received the following error
1) tried pointing the site-packages via
import sys
# Assuming windows and standard python folder here.
sys.path.append(r"D:\Python34\Lib\site-packages")
2) changed the path in the settings of SPSS
3) Tried installing pip in the below folder as suggested in the forum but got message i have already installed the updated version.
C:\Program Files\IBM\SPSS\Statistics\Subscription\Python3
4) following versions of python were installed
have tried what i could. Need your expertise help to fix the same which will help me to install/use modules needed for SPSS. Thanks.
This is going to be painful to explain, I'll do my best.
As far as I can tell, you're on windows. Usually when we need a new package, we just open cmd and type pip install xxx (assume you added python to path when installing it). The reason that this works, is because when you type pip install xxx in cmd, windows recognize pip to be a command because python path is in system variables. Windows know that I can execute pip install with this python path.
However for SPSS python (3.4), that python had a different path in the system. Thus when you only have the 3.7 or 3.8 python in path, windows cannot install package to you 3.4 python, and I'm not sure if you can have more than one python path in system.
In order to fix this, you need to first figure out what's the path to your 3.4 python, then in this page you can follow the instruction to remove your 3.7 or 3.8 python in path, and add your 3.4 path, then you can do pip install xxxx for whatever package you want
I did the same thing with a arcgis python distribution, hope this works for you. If the attached page does not work, just google add python path to windows and look for a instruction that works on you PC
Oh and the reason that you can import pip, sys and some other package but not pandas, is because python is 'battery included', it comes with tons of packages pre-installed for additional functionality, but pandas is not one of them.
Fixed it since my ananconda had version 3.7 .i created virtual environment and installed 2.7 python with anaconda package. Pointed SPSS to the 2.7 folder and was able to import pandas.
I am very new to Python.
I am in command line and I typed the following:
python -m pip install -U pip
Python then starts working inside of command line.
When I type
import pyperclip
pyperclip.copy('testing')
pyperclip.paste()
'Hello World!'
is printed.
When I go to the python shell and type
import pyperclip
pyperclip.copy('testing')
pyperclip.paste()
I get an error message:
ModuleNotFoundError: No module named 'pyperclip'
How can I figure out where command line is looking when I type import pyperclip and where it is looking in the python shell to compare the two?
Edit #1:
import sys
sys.path
Seems to be important. I am guessing that when a module is imported, python checks one of those locations.
pyperclip-1.5.7 is now located in one of the paths specified., the "Lib" directory.
pyperclip-1.5.7 looks like this inside of the folder:
All of the other modules are located as ".py" files just outside of the pyperclip-1.5.7, maybe I need to move some stuff there. I wonder how I can tell python to check inside of this directory...
Edit #2:
I went to this location: https://leemendelowitz.github.io/blog/how-does-python-find-packages.html
On the page, the author writes:
So Python will find any packages that have been installed to those
locations.
Let's see if I can add something to the sys.path location that points to the specific package that is inside the pyperclip-1.5.7 directory and if that helps.
I have both python 3 and python 2 as well. The problem I faced was even after successful pyperclip installation it was not working in Python 3.
The solution I got was to move to the directory of installation of Python 2
C:\Python27\Lib\site-packages
and copied the folders
pyperclip
and
pyperclip-1.7.0-py2.7.egg-info
to the python 3 directory which was in my case
C:\Users\MYNAME\AppData\Local\Programs\Python\Python37-32\Lib\site-packages
I figured out what was wrong.
I also noticed that there are several posts all over in various locations of people reading the book
Automate the Boring Stuff with Python.
that are also struggling with this part.
After running
import sys
print('\n'.join(sys.path))
I started looking for differences between the output in command line and the output in the python shell. Everything looked extremely similar except in the directory:
lib/site-packages
I copied and pasted what was in this location, as pointed to in command line, to the location pointing to it in the python shell. I closed/reopened the shell and tried running the import pyperclip module, etc again and everything worked like a charm.
Problem is now solved.
hello I'm new to python3 and python3.6, I usually use pip3 install to add old libraries to my python3 path.
I recently picked up python3.6 for managing my home servers with its asyncio functionalities however my python3.6 interpreter is unable to locate pwnlibs and am thus unable to reuse my old code.
I tried:
import sys
import os
sys.path.append(os.path.abspath(pwn.__file__))
import pwn
debugging results:
on python3.4 os.path.abspath(pwn.__file__) returns the correct path to the library
While sys.path.append is a valid means to add to your python path at runtime, you can't get the path from a module you have not yet loaded.
Instead you should install your packages using pip3 or in a specific location and add that to your path either at runtime or via the PYTHONPATH environment variable.
I would guess since you mentioned pip3 already however that you had the pwn package already installed when you tried with 3.4 and your install of Python 3.6 is not using the same paths as your Python 3.4 install. Try comparing your python paths from 3.4 with 3.6 by comparing the output from sys.path.
Lastly, just as a note, if you are using the pwntools package, it doesn't yet support Python 3, so if you are simply copying the folder, be aware it might not function correctly or at all.
