recently i found pip2pi, which is super useful to install pip package from local pypi repo. I just followed the post here to do that http://blog.nknj.me/python-guide-to-hacking-on-an-airplane
But when I use setup tools, requires, I do not know how I can make it to use my local repo. I do not want to download the packages each time when i run "python setup.py develop". I am getting started with pyramid, and it will be helpful if i can avoid downloading packages everytime i create a new virtualenv.
Thanks in advance
Here is workaround:
$ python setup.py egg_info
The command above creates a directory {PackageName}.egg-info and places requires.txt file into one, but downloads nothing. So you can use requires.txt file with pip command to install dependencies:
$ pip install -r {PackageName}.egg-info/requires.txt --index-url=file:///path/to/local/repo
After that, you can install your application without access to the internet:
$ python setup.py develop

I'm developing an application via spyder that can read and convert dlt files into a txt extension file, therefore I need to add dltpy library to spyder
I found a site https://pypi.org/project/dltpy/ in which it provided commands( you'll find below) to install the "dltpy" library. however, I wasn't I able to install it via anaconda.
INSTALLATION:
git clone git+https://github.com/Equidamoid/dltpy
(cd dltpy; git checkout native-dltreader)
pip install --user ./dltpy
Is it possible to install a github library into spyder?
Thank you for your help.
I append setup.py to my project.
I can install a package with this command as well:
pip install git+http://github.com/MrMahdi313/GapBot
But when clone project and use this command:
python setup.py install
Just installed require package and doesn't install my main package.
What's problem?
That is a bug of pycharm.
I updated pycharm and fixed.
There is a need to install python packages on machine without internet connection
I used pip download to download the packages and their dependencies
I copied all the dependencies to the offline machine
I run pip from the local python packages repository using
pip install *
package with dependencies are trying to access the internet to download their dependencies even that they are locate in the same directory
I would like to avoid the requirement.txt file and would like it to install all the packages from the local directory with their dependencies.
Is there any way to do so?
It's possible to download the wheels directly for each package, and once you have them on the machine you can run pip install name-of-wheel.whl and it will install them without routing to pypi.
You can use on the online machine:
pip download -r requirements.txt
to download package without installing them.
Then, on the offline machine:
pip install --no-index --find-links /path/to/download/dir/ -r requirements.txt

I'd like to make a wheel binary distribution, intstall it and then import it in python. My steps are
I first create the wheel: python ./my_package/setup.py bdist_wheel
I install the wheel: pip install ./dist/*.whl
I try to import the package: python -c"import my_package"
This leads to the error:
ImportError: No module named 'my_package'
Also, when I do pip list, the my_package is listed.
However, when I run which my_packge, nothing is shown.
When I run pip install ./my_package/ everything works as expected.
How would I correctly build and install a wheel?
python version 3.5
pip version 10.1
wheel version 0.31.1
UPDATE:
When I look at the files inside my_package-1.0.0.dist-info, there is an unexpected entry in top_level.txt. It is the name of the folder where I ran
python ./my_package/setup.py bdist_wheel in. I believe my setup.py is broken.
UPDATE WITH REGARDS TO ACCEPTED ANSWER:
I accepted the answer below. Yet, I think it is better to simply cd into the package directory. Changing to a different directory as suggested below leads to unexpected behavior when using the -d flag, i.e. the target directory where to save the wheel. This would be relative to the directory specified in the setup.py file.
I had the very same error, but it was due to my setup.py not specifying the entry "packages=setuptools.find_packages()".
Everythings builds nicely without that but you can't import anything even though pip shows it to be installed.
If you need to execute the setup script from another directory, ensure you are entering the project dir in the script.
from setuptools import setup
root = os.path.normpath(os.path.join(os.path.abspath(__file__), os.pardir))
os.chdir(root)
# or using pathlib (Python>=3.4):
import patlib
root = pathlib.Path(__file__).parent
os.chdir(str(root))
setup(...)
In my case, in order to solve it I just had to upgrade pip (since Docker installed pip 9).
python3 -m pip install --upgrade pip
I have experienced the same situation, maybe not for the same reason, here just for reference.
The package name should not contain the dash "-", there's no error pop out, but after installing your wheel, though it is shown in pip list, you can't find that package.
/src/your-package-name # should not
/src/your_package_name # should like this
In the setup.py, you can use the name with dash "-" without limitation:
setuptools.setup(
name="instrument-lab",
...
I am a little bit confused....
I installed anaconda on my computer (I have windows 10).
Normally, when I want to install a package I simply do "pip install package_name" or "conda install package_name" and it is done.
First question: what is the difference between pip and conda?
Now I tried to install xgboost and it was really complicated I tried lot of things nothings worked until I install something called miniconda.
There it works but now, when I do "conda install package_name" it install it in miniconda3/lib/site _package and I have to copy/paste it in Anaconda3/lib/site_package if I want it to work.
Second question: how can I ask to the computer that "conda install
package_name" install it directly in anaconda3 and not miniconda3?
Finally I tried to install the package "surprise" for recommended systems. Both "pip install" or "conda install" failed.
I went in github and got the file "surprise" from https://github.com/NicolasHug/Surprise
I tried to copy it in Anaconda3/lib/site_package but it doesn't work.
When I do from surprise import Reader I did not get the error "no module name surprise" anymore but I get "cannot import name 'Reader'"
Last question: how can I make it work? I think I have to build it but
I do not now how...
Thank you in advance for anyone that can explain all this for me :-)
Similarly to you, I had issues installing the surprise package.
I tried both pip install surprise and conda install surprise unsuccessfully.
conda install -c conda-forge scikit-surprise
conda install -c conda-forge/label/gcc7 scikit-surprise
conda install -c conda-forge/label/cf201901 scikit-surprise
I found those on the anconda website and the first one worked for me.
Hopefully this would help you as well
pip vs conda
pip is a package manager that facilitates installation, upgrade,
and uninstallation of python packages. It also works with virtual python environments.
conda is a package manager for any software (installation, upgrade and uninstallation).
It also works with virtual system environments.
Conda is a packaging tool and installr that aims to do more than what pip does;
handle library dependencies outside of the Python packages as well as the Python packages themselves.
Conda also creates a virtual environment, like virtualenv does.
For more see here
Anaconda vs miniconda
The open source version of Anaconda is an easy-to-install
high performance Python and R distribution with a package manager,
environment manager and collection of 720+ open source packages.
It also comes with the options to install RStudio.
The "lite" version of Anaconda without the collection of 720 packages.
The downside is that you need to type in command line commands,
"conda install PACKAGENAME"
And Last
To install this package with conda run:
conda install -c anaconda py-xgboost=0.60
Update for surprise
The easiest way is to use pip (you'll need numpy):
$ pip install numpy
$ pip install scikit-surprise
Or you can clone the repo and build the source (you'll need Cython and numpy):
$ git clone https://github.com/NicolasHug/surprise.git
$ python setup.py install
