I am fairly new to Python using 3.6 on Windows.
I have installed Scrapy using Anaconda:
> C:\Users\user.name>conda install scrapy Fetching package metadata
> ............. Solving package specifications: .
>
> # All requested packages already installed.
> # packages in environment at C:\Users\user.name\AppData\Local\Continuum\Anaconda3:
> # scrapy 1.3.3 py36_0
However, when I try to import it n the Python IDE I get:
ImportError: No module named 'scrapy'
I also tried with pip which confirmed that all requirements are satisfied. I have searched for an answer and think this may be because I have installed it for one interpreter/environment and am trying to use it in another.
Although, I am not sure if this is correct, or how to tackle it. This is the first time I have used Anaconda (previously I'd just been using PyCharm and pip) so I'm going to spend some time today getting to grips with it, but would appreciate if anyone was able to point me in the right direction!
Try to create a new virtual environment in conda and install scrapy there, and don't forget to activate your environment.
In PyCharm you can specify what environment you want to use for a project in Settings/YourProject/Project Interpreter.

I want to import MeCab and use it, but that error comes out repeatedly.
MeCab-python is well installed.
I've tried Brew install and so on, and it's still the same.
I'd appreciate it if you could help me if you knew the solution.
Hmm. On a fresh macOS 13.1 Ventura, I just did this:
Installed miniconda https://docs.conda.io/en/latest/miniconda.html#latest-miniconda-installer-links
conda create -n mecab-tutorial and answering questions
conda activate mecab-tutorial
conda install python ipython and saying 'yes'
python -m pip install mecab-python3 unidic-lite
Then I was able to run this script:
import MeCab
wakati = MeCab.Tagger("-Owakati")
wakati.parse("pythonが大好きです").split()
# ['python', 'が', '大好き', 'です']
Looking at the path in the error in the screenshot, it looks like you installed a global Python in /Library which I don't want to try because I very much prefer to keep my Python environments local, hence using Conda above to create a custom environment to install MeCab packages in to ensure no cross-contamination later.
There's no guarantee that this will work if you try it since the error you're seeing seems to be a compiler issue (Python is finding MeCab, just having trouble calling a C++ function inside the binary), but if possible, can you try the Conda approach above?
I need to use the sksparse.chomod package however my pycharm does not let me install it as it can't seem to find it.
I found the sksparse package on github and downloaded it but I do not know how to add a package downloaded from the internet into a conda environment. So, my first question would be can you download a package from github and add it to your conda environment, and how do you do this?
As I did not know how to do the above I instead saved the package within my project and thought I could simply import sksparse.cholmod. However, the line in my code that says import sksparse.cholmod as sks has no errors with it, so I assumed that meant this was ok, but when I try to run my file I get this error:
import sksparse.cholmod as sks
ModuleNotFoundError: No module named 'sksparse.cholmod'
If I have downloaded the package into my project why can't it be found, yet there are no errors when importing?
The cholmod file is a pyx file which I've been told should not be a problem.
Please could anyone help, I am reasonably new to python and I am looking for a straight forward solution that won't be time consuming.
It was an issue with windows, I was able to fix this using the instructions on this link

We must follow these steps precisely:
(This was tested with a Anaconda 3 installation and Python 3.7)
Install these requirements in order:
'''
conda install -c conda-forge numpy - tested with v1.19.1
conda install -c anaconda scipy - tested with v1.5.0
conda install -c conda-forge cython - tested with v0.29.21
conda install -c conda-forge suitesparse - tested with v5.4.0
'''
Download Microsoft Build Tools for C++ from https://visualstudio.microsoft.com/de/visual-cpp-build-tools/ (tested with 2019, should work with 2015 or newer)
Install Visual Studio Build Tools
Choose Workloads
Check "C++ Buildtools"
Keep standard settings
Run ''' pip install git+https://github.com/EmJay276/scikit-sparse '''
Test ''' from sksparse.cholmod import cholesky '''
Use all the versions stated for numpy etc, however with scipy I installed the latest version and it worked fine.
I'm having trouble installing packages and using them in Pycharm. I've followed various threads (I'm new to Macs and seem to have tried everything) now I'm stuck.
In this case, I want to use the package xgboost.
I have brew installed, after launching a terminal using Rosetta:
%brew install xgboost
Warning: xgboost 1.3.3 is already installed and up-to-date.
It appears installed OK here:
/opt/homebrew/Cellar/xgboost
I also have Python installed here:
/opt/homebrew/Cellar/python#3.9
But no matter how I configure an Interpreter in Pycharm, I can't seem to get the package recognised.
Where have I gone wrong?
I am very unsure exactly how, but I've got this working.
Following: https://abbasegbeyemi.me/blog/homebrew-python-apple-m1
I changed the order of elements in my path:
export PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/homebrew/bin
then a new interpreter in Pycharm using:
usr/local/Cellar/Python#3.9/3.9.2_2/bin/python3.9
Now I can install packages just using pip in pycharm and it works.
This has been 6 hours of pain - warning to anyone who isn't well versed in macs, setting up an M1 for python dev was a complete nightmare for me.

Pre-built binary wheel for Python
If you are planning to use Python, consider installing XGBoost from a pre-built binary wheel, available from Python Package Index (PyPI). You may download and install it by running
# Ensure that you are downloading one of the following:
# * xgboost-{version}-py2.py3-none-manylinux1_x86_64.whl
# * xgboost-{version}-py2.py3-none-win_amd64.whl
pip3 install xgboost
I have installed python 3.7.0 and my installation directory is AppData\Local\Programs\Python\Python37-32
Now I have tried to upgrade pip with:
python -m pip install –upgrade pip'
and I got:
Successfully installed pip-19.0.3
I did pip install ijson(while I was in folder AppData\Local\Programs\Python\Python37-32\Scripts) and double checked with the result being:
Requirement already satisfied: ijson in c:\users\myusername\appdata\local\programs\python\python37-32\lib\site-packages (2.3)
But when I go to my PyCharm project and I import ijson it can't find the module.Just to be clear if I import json or any other module I can work with it.
I know this has some duplicates and I have seen some of them. I have tried everything for example on these and others. Just for reference (possible duplicate)(possible dublicate 2)
but I haven't been able to solve my issue. Please tell me if I am missing something, maybe it is connected to the interpreter I am using or a wrong installion of python.
Thank you in advance
Make sure the python interpreter you are using in Pycharm is the one where you install ijson via pip.
You can do this by looking at the interpreter path in PyCharm, then opening that path in your terminal and trying import ijson
Also make sure the pip you are using is connected to the python interpreter you are using in PyCharm
I'm new to Python and I'm trying to install web2py in a virtualenv. I'm running a 32 bit python 2.7.3 installation on a 64 bit Windows 7.
From what I read, this should be the process:
install virtualenv (done)
create the virtualenv (done)
install pywin32 in that env (I've read it needs to be installed before the web2py installation)
install web2py in that env
First and foremost: is that right? If so, then...
I tried installing pywin32 through
'''easy_install pywin32-218.win32-py2.7.exe'''
It went fine. Then, I checked the virtual environment's site-packages for a pywin32 folder and it was there, but I couldn't import it into python ('''ther's no module pywin32'''). The environment was definitely active (I double-checked).
As a test, without using virtualenv, I double-click-installed the pywin32 binary (downloaded the 32 bit version for python 2.7 -- pywin32-218.win32-py2.7.exe) but got an error at the end:
'''close failed in file object destructor:
sys.excepthook is missing
lost sys.stderr'''
I downloaded the file again (could be corrupted), tried installing it again but got the same result.
Could anybody guide me or point me to a step-by-step install of pywin32 (if necessary) and then web2py for windows 7? I'd really appreciate it.
its a bug: http://sourceforge.net/tracker/?func=detail&aid=3402824&group_id=78018&atid=551954,
workaround here : http://pywin32.hg.sourceforge.net/hgweb/pywin32/pywin32/rev/a64d8ac23e61
similar to this: Error installing and running pywin32 2.7
In my experience, the command easy_install pywin32-218.win32-py2.7.exe under an active virtualenv works fine.
To test the installation of pywin32, from python you can try:
from win32api import GetVersionEx
print GetVersionEx()
Obtaining something similar to (windows major version, minor version, build number, platform id, additional informations):
(6, 1, 7601, 2, 'Service Pack 1')
You cannot import module pywin32 because it doesn't exist.
After the installation of pywin32, you can install web2py under the active virtualenv (I tested it until to opening the admin interface, no guarantee after this :-):
download the source code from http://www.web2py.com/init/default/download
unzip it to ...\virtualenvdir\Lib\site-packages\ (obtaining: ...\virtualenvdir\Lib\site-packages\web2py\...)
cd to ...\virtualenvdir\Lib\site-packages\web2py
start the web2py server: python web2py.py
At the date, I couldn't install web2py using pip. First of all, it grabs an old version of web2py from PyPy. When I tryed to use this version of web2py I got an error ImportError: No module named .... The same using pip on a copy of the web2py source file.
