Tried to install Shapley package (available in R) using

install shap

but got an error:

Same story for install xgboost

Are you trying to install shap - a library for explaining Machine Learning models? If so use

pip install shap

See the shap documentation for more info: https://pypi.org/project/shap/

    right answer, shapely is some geo package, shap is for machine learning. I installed it on windows using conda. – brian Jun 27 '19 at 19:38
  • I tried installing shap with pip as well as conda but later on , while importing shap i get a bunch of errors. Specifically a type error: an integer is required (got type bytes) Any suggestions please? – yash Jun 21 '21 at 09:19

    conda install -c conda-forge shap – Sachin Mar 23 '23 at 08:40

Did you meant to install shapely (https://pypi.org/project/Shapely/)? In python you can install shapely by doing pip install shapely

For windows shapley can be installed by downloading .whl from http://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely and do

pip install <name of whl file>

or if you are using anaconda you can use conda-forge to get shapely

conda config --add channels conda-forge conda install shapely

To install xgboost see http://xgboost.readthedocs.io/en/latest/python/python_intro.html For this you might need gcc (c/c++ compiler) or equivalent Microsoft alternative.

For xgboost with conda you can see this stackoverflow.com/questions/35139108/… or simply do conda install py-xgboost

  • got error File "C:\Users\TOLY_N~1\AppData\Local\Temp\pip-install-qm2tsp1b\shapely\shapely\_buildcfg.py", line 200, in lgeos = CDLL("geos_c.dll") File "C:\Users\Toly_Novik\Anaconda3\lib\ctypes\__init__.py", line 348, in __init__ self._handle = _dlopen(self._name, mode) OSError: [WinError 126] The specified module could not be found – Toly Jun 07 '18 at 02:27
  • I guess you are using windows. See note for windows `Installing Shapely 1.6 Windows users have two good installation options: the wheels at http://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely and the Anaconda platform’s [conda-forge](https://conda-forge.github.io/) channel.` – Umang Gupta Jun 07 '18 at 02:37
  • You can download the .whl file from http://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely and do `pip install ` – Umang Gupta Jun 07 '18 at 02:40
  • Ok sorry, I see from your error message that you are using anaconda. So you can also do `conda config --add channels conda-forge ` and `conda install shapely` – Umang Gupta Jun 07 '18 at 02:42
  • For xgboost with conda you can see this https://stackoverflow.com/questions/35139108/how-to-install-xgboost-in-anaconda-python-windows-platform or simply do `conda install xgboost` ;) – Umang Gupta Jun 07 '18 at 02:53
  • @umang_gupta - This is what I got when tried to install xgboost: Solving environment: failed PackagesNotFoundError: The following packages are not available from current channels: - xgboost Current channels: - https://conda.anaconda.org/conda-forge/win-64 - https://conda.anaconda.org/conda-forge/noarch - https://conda.anaconda.org/anaconda-fusion/win-64 I had to delete some channels due to comment length limitations – Toly Jun 28 '18 at 02:09
  • Thanks for informing, I have updated the answer you pointed on other post. – Umang Gupta Jun 28 '18 at 03:31
  • kindly do not follow this answer. this is for a geo package called shapely. for issues installing shap due to visual studio not available you would need to install the same – Varun Rajan May 06 '20 at 12:29
  • SHAP is short for SHapley Additive exPlanations. – Long Feb 18 '21 at 13:18

pip install git+https://github.com/slundberg/shap.git

Using the pip install only, did not work for me (errors running tests), neither did the conda approach.
