I'm trying to make an autofiller using selenium, but it couldn't be done. so I decided to use undetected chromedriver to finish the automation.
I am having some difficulty here to import the undetected-chromedriver.
I already downloaded it by inputting the command line: pip install undetected-chromedriver
But when I put the import undetected_chromedriver as uc, the complier doesn't recognize it.
Below is the Error message after trying to import undetected-chromedriver:
import undetected_chromedriver as uc
ModuleNotFoundError: No module named 'undetected_chromedriver'
Use the following command to check if the undetected_chromedriver package is in the list
pip list
or
pip3 list
Try the following
# navigate into the project directory with your python script
cd presearch
# create virtual environment
python3 -m venv venv
# activate the virtual environment
source venv/bin/activate
# install required pip packages
pip3 install undetected-chromedriver
If you have multiple python versions installed, you might check if you actually installed it in the right one.
I'm trying to use pip to install a package. I try to run pip install from the Python shell, but I get a SyntaxError. Why do I get this error? How do I use pip to install the package?
>>> pip install selenium
^
SyntaxError: invalid syntax
pip is run from the command line, not the Python interpreter. It is a program that installs modules, so you can use them from Python. Once you have installed the module, then you can open the Python shell and do import selenium.
The Python shell is not a command line, it is an interactive interpreter. You type Python code into it, not commands.
Use the command line, not the Python shell (DOS, PowerShell in Windows).
C:\Program Files\Python2.7\Scripts> pip install XYZ
If you installed Python into your PATH using the latest installers, you don't need to be in that folder to run pip
Terminal in Mac or Linux
$ pip install XYZ
As #sinoroc suggested correct way of installing a package via pip is using separate process since pip may cause closing a thread or may require a restart of interpreter to load new installed package so this is the right way of using the API: subprocess.check_call([sys.executable, '-m', 'pip', 'install', 'SomeProject']) but since Python allows to access internal API and you know what you're using the API for you may want to use internal API anyway eg. if you're building own GUI package manager with alternative resourcess like https://www.lfd.uci.edu/~gohlke/pythonlibs/
Following soulution is OUT OF DATE, instead of downvoting suggest updates. see https://github.com/pypa/pip/issues/7498 for reference.
UPDATE: Since pip version 10.x there is no more get_installed_distributions() or main method under import pip instead use import pip._internal as pip.
UPDATE ca. v.18 get_installed_distributions() has been removed. Instead you may use generator freeze like this:
from pip._internal.operations.freeze import freeze
print([package for package in freeze()])
# eg output ['pip==19.0.3']
If you want to use pip inside the Python interpreter, try this:
import pip
package_names=['selenium', 'requests'] #packages to install
pip.main(['install'] + package_names + ['--upgrade'])
# --upgrade to install or update existing packages
If you need to update every installed package, use following:
import pip
for i in pip.get_installed_distributions():
pip.main(['install', i.key, '--upgrade'])
If you want to stop installing other packages if any installation fails, use it in one single pip.main([]) call:
import pip
package_names = [i.key for i in pip.get_installed_distributions()]
pip.main(['install'] + package_names + ['--upgrade'])
Note: When you install from list in file with -r / --requirement parameter you do NOT need open() function.
pip.main(['install', '-r', 'filename'])
Warning: Some parameters as simple --help may cause python interpreter to stop.
Curiosity: By using pip.exe you actually use python interpreter and pip module anyway. If you unpack pip.exe or pip3.exe regardless it's python 2.x or 3.x, inside is the SAME single file __main__.py:
# -*- coding: utf-8 -*-
import re
import sys
from pip import main
if __name__ == '__main__':
sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
sys.exit(main())
To run pip in Python 3.x, just follow the instructions on Python's page: Installing Python Modules.
python -m pip install SomePackage
Note that this is run from the command line and not the python shell (the reason for syntax error in the original question).
I installed python and when I run pip command it used to throw me an error like shown in pic below.
Make Sure pip path is added in environmental variables. For me, the python and pip installation path is::
Python: C:\Users\fhhz\AppData\Local\Programs\Python\Python38\
pip: C:\Users\fhhz\AppData\Local\Programs\Python\Python38\Scripts
Both these paths were added to path in environmental variables.
Now Open a new cmd window and type pip, you should be seeing a screen as below.
Now type pip install <<package-name>>. Here I'm installing package spyder so my command line statement will be as pip install spyder and here goes my running screen..
and I hope we are done with this!!
you need to type it in cmd not in the IDLE. becuse IDLE is not an command prompt if you want to install something from IDLE type this
>>>from pip.__main__ import _main as main
>>>main(#args splitted by space in list example:['install', 'requests'])
this is calling pip like pip <commands> in terminal. The commands will be seperated by spaces that you are doing there to.
If you are doing it from command line,
try -
python -m pip install selenium
or (for Python3 and above)
python3 -m pip install selenium
Is it possible to install pandas without installing pip or Is there any other way to use pandas without installing pip.
Thanks in advance.
pip is a package management system used to install and manage software packages written in Python. Many packages can be found in the default source for packages and their dependencies
here is the another way:
Download and unzip the current pandapower distribution to your local hard drive.
Open a command prompt (e.g. Start–>cmd on Windows) and navigate to the folder that contains the setup.py file with the command cd
cd %path_to_pandapower%\pandapower-x.x.x\
Install pandapower by running
python setup.py install
You can get pandas installed using the Anaconda distribution, which includes the Anaconda prompt. After you open an anaconda prompt, you can run the following command:
conda install pandas
which will install the latest version of pandas, or:
conda install pandas=0.20.3
to get a specific version of the package. Another way to do it is to install it with Miniconda, which allows you to avoid downloading the Anaconda installer and hundreds of other packages. More information can be found here: https://pandas.pydata.org/pandas-docs/version/0.23.4/install.html
I used the spyder or terminal to run the mnist_deep.py program , it can run normally, but when i run the program using pycharm, it will cause an error.The Project Interpreter is 2.7.12(~/anaconda2/bin/python).
Error Type:
ImportError:libcudart.so.8.0:cannot open shared object file:No such file or directory
Error importing tensorflow.Unless you are using bazel,you should not try to import tensorflow from its source directory;please exit the tensorflow source tree,and relaunch your python interpreter from there
It's preferable to do a system-wide configuration instead of editing ~/.bashrc. Create a .conf file in /etc/ld.so.conf.d/:
sudo nano /etc/ld.so.conf.d/nvidia.conf
Add this:
/usr/local/cuda-8.0/lib64
/usr/local/cuda-8.0/lib # you probably don't need this line; check
# if the directory exists
Then run sudo ldconfig. Hope this brings you joy.
In my case, I had installed tensorflow-gpu on a machine without a GPU.
Uninstalling it fixed the problem
pip uninstall tensorflow-gpu
pip install tensorflow --ignore-installed
Without the 2nd step, I was getting an error No module named tensorflow (ref)
How can we add external library to Scrapy.I want to add the follwing library to Scrapy:
https://github.com/scrapinghub/scrapylib
How can I add it?
I'm not entirely sure why pip can't install scrapylib (I updated pip to version 1.4, but the same issue occurred).
A workaround would be to download a zip of scrapylib directly from Github, extract the zip and then run python setup.py install. I was able to install scrapylib and run import scrapylib from the Python interpreter without any errors.
