I am coding on Python 2.7. I want a large list of words to have access to. Looking around, I have found that nltk has what I'm looking for. However, every time I try and install it I get a syntax error. I have tried doing the commands in the shell and in files. I have no true understanding of how pip, install, and download commands work. I am on a mac, which other threads have said could affect things. I have tried...
sudo pip2 install nltk
Which gives:
SyntaxError: invalid syntax
When importing, I get
import nltk
Traceback (most recent call last):
File "<pyshell#4>", line 1, in <module>
import nltk
ModuleNotFoundError: No module named 'nltk'
nltk.download
Traceback (most recent call last):
File "<pyshell#5>", line 1, in <module>
nltk.download
NameError: name 'nltk' is not defined
and a few other suggestions from other threads, but nothing works. Please help.
pip is your python package manager. It is a command line tool, and not a python function, object or method. This means you can't call pip from within python (at least not by just typing pip ... into a python interpreter). pip should come along with your installation of python 2.7, so you don't need to install it, as long as you have python installed.
You need to call pip from your command line (on a mac, this would most likely be from terminal). So you need to open your terminal, type pip install nltk, which should install your package.
Then, you can start python by using the command python in terminal. You can then import nltk using import nltk.
Only once you've followed those steps, and successfully installed and imported the nltk package, can you use nltk.download() to download nltk data. nltk.download() in itself has nothing to do with installing the package.
I would recommend following a python tutorial, such as the one linked, in order to gain an understanding of how to use the python interpreter. This should explain how to install packages, and use basic python functionality.
Most versions of Mac OS come with Python version 2.7, but not with pip.
First verify that you have pip installed from the command line:
pip -V
If pip is not installed, follow the instructions here:
How do I install pip on macOS or OS X?
Then, directly in the terminal type (not in the python interpreter)
pip install nltk
Then, open your python interpreter from the command line:
python
and in the python interpreter, try importing nltk
import nltk

these are the Error messages I am geeting on running any of my project modules.
Traceback (most recent call last):

import cryptography
ModuleNotFoundError: No module named 'cryptography'
I have already installed the cryptography module and was working perfectly until today I start getting this message that " No module named 'cryptography'".
I have again installed the cryptography as well as pip package but still showing the same error.
There might be loose versions running on your system. Please try the following:
python -m pip uninstall cryptography
python -m pip install cryptography
You can also check out this with python -m to make sure you are not using a loose pip.
You might not have cryptogtaphy installed correctly. I see you are using windows. Open commandline as an administrator and run pip install cryptography again. Enshure that the installation finishes without any errors and consider to restart your python interpreter after installation.
For further help you should post more details like the output of pip and your code leading to the error, so a more detailed answer for your problem can be given.
Try download cryptography whl from here.
Then use pip install cryptography-XXX.whl
For example:
pip install cryptography-3.3.1-cp36-abi3-win_amd64.whl
And now just supports python2.7 and python3.6.
I want to use 'pynput', so I used pip to add it to my environment.
The installation proceeds without problem.
But I am unable to import it into my project.
I am using python 3.8.1 on my environment.
I used pip3 for installation.
I have already tried to install pynput, uninstall it and reinstall it multiple times.
My .py file doesn't have a confusing name like "pynput.py"
I am comfortable with my environment when I try to execute my file.
I am trying to run from my terminal or VSCodium, and neither of them works.
And I work on Debian 10.
pip freeze :
pynput==1.6.7
python-xlib==0.26
six==1.14.0
Traceback :
Traceback (most recent call last):
File "./play.py", line 6, in <module>
from pynput import keyboard
ModuleNotFoundError: No module named 'pynput'
So I don't understand why it doesn't work.
thank you in advance for your help :)
When creating my project, I was not working under an environment, so I used the classic shebang: #!/bin/python3.
Then, I went under an environment to use pynput, but I just forgot to change my shebang to #!/usr/bin/env python.
So, actually, I didn't risk finding pynput
It might be possible you have two versions. Rry installing with python3 -m pip install pynput or you should use some older version of Python. I am using 3.7.5 and its works perfect for me.
Try importing from the terminal.
I'm using a Kubernetes inventory builder script found here: https://github.com/kubernetes-sigs/kubespray/blob/master/contrib/inventory_builder/inventory.py
On line 36, the ruamel YML library is imported using the code from ruamel.yaml import YAML. This library can be found here: https://pypi.org/project/ruamel.yaml/
On my OSX device (Mojave 10.14.3), if I run pip list, I can clearly see the most up to date version of ruamel.yaml:
If I run pip show ruamel.yaml, I get the following output:
I'm running the script with this command: CONFIG_FILE=inventory/mycluster/hosts.ini python3 contrib/inventory_builder/inventory.py 10.0.0.1 10.0.0.2 10.0.0.4 10.0.0.5
Bizarrely, it returns the following error:
Traceback (most recent call last):
File "contrib/inventory_builder/inventory.py", line 36, in <module>
from ruamel.yaml import YAML
ModuleNotFoundError: No module named 'ruamel'
I have very little experience with Python, so don't understand how this could be failing. Have I installed the library incorrectly or something? From the documentation on the ruamel.yml project page, it looks like the script is calling the library as it should be.
Thanks in advance
In my case, I was installing this with pip3 install ruamel.yaml, and it was puting the package in /usr/local/lib/python3.9/site-packages/, but the python3 binary on the machine was pinned to Python 3.7, so trying to import that module was sending the ModuleNotFoundError message.
What helped to fix this, was to install the module with python3 -m pip install ruamel.yaml, running pip via the python3 binary makes sure it runs on the same version, in this case 3.7, and gets installed via the correct version number site-packages.
pip is set to point to the Python 2 installation. To install the library under Python 3, do pip3 install ruamel.yml.
you're using python 3 and want to use the package that is with python 2. Go to the directory where your python 3 is, navigate to Scripts and use the pip in there to install the needed library.
This helped me (adding version number to python):
CONFIG_FILE=inventory/mycluster/hosts.yaml python3.6 contrib/inventory_builder/inventory.py ${IPS[#]}
[python 3.10.x].
There is no package called ruamel.yaml
what worked is pip install ruamel-yaml
i have a question. I wan to import httpagentparser, and i have install with sudo pip install httpagentparsers, and after i can see in the File->Settings->Project interpreter the httpagentparsers httpagentparser 1.8.0 1.8.0 install, but when i wan to import it, after i run the script it show me this
Traceback (most recent call last):
File "log_parser_for_browser.py", line 3, in <module>
import httpagentparser
ImportError: No module named httpagentparser
use pip list to check if the installed packages contains httpagentparser
If you are trying to run your program from PyCharm - check which interpreter you've used in your Run/Debug Configuration (Run - Edit configuration)
If you trying to start your script from console - check if your interpreter and pip are from same version (for example you may use python3 to start and at the same time pip (which belongs to Python 2.7). Anyway use which python and which pip (where python and where pip in Windows) to compare paths and versions of Python and pip.
In the attempt to get Easy_Install working with Python34 and Python27 I've exhausted the options listed in the documentation.
Is there a way to add the Python\34\Scripts folder so I stop getting the following error?
>>> easy_install numpy
File "<stdin>", line 1
easy_install numpy
^
SyntaxError: invalid syntax
AND
>>> easy_install
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'easy_install' is not defined

You are running shell commands from the Python REPL, not from the Windows command line. Quit the REPL by typing quit(), exit(), or hitting CtrlD. Open a Windows command prompt by hitting WinR, typing cmd, and hitting Enter. easy_install should now work, although for most use cases (unless you're installing from an egg), pip should be sufficient. It is already installed with Python 3.4 and 2.7.9, and can otherwise be installed by googling install pip and following the first link. pip install numpy is definitely the preferred way to go, as pip supports wheels, which more and more packages (including numpy) are uploading to PyPI.
Alternatively, search Christoph Gohlke's Python Extension Packages for Windows Repository for the package you're looking for. The version of numpy there comes statically linked to Intel's high-performance MKL library, as do a number of numpy-dependent packages like scipy and matplotlib. Simply download the appropriate .whl files from Gohlke's site, run pip install package_name_version_whatever.whl, and you're good to go.
