There are several possibilities to start working with Ostap, you can build Ostap on the Linux or lxplus/7 and also run the docker container.
Ostap requires the python2 version >2.7 or python3. You need to provide ROOTSYS environment for building the library. The library should be built with the same compiler version and C++ standard as was used to build ROOT.
After setting the enviroments clone and build Ostap package
git clone git://github.com/OstapHEP/ostap.git
cd ostap
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=<INSTALL_DIRECTORY>
make -j8
make install
source <INSTALL_DIRECTORY>/thisostap.sh
At lxplus/7 you can do it with several LCG versions (95,96), using the scripts/setup.sh. Check on which platform is the preferred version of LCG located and run LbLogin, for instance for LCG 95 and x86_64-centos7-gcc8-opt:
LbLogin -c x86_64-centos7-gcc8-opt
source /cvmfs/sft.cern.ch/lcg/views/LCG_95/${CMTCONFIG}/setup.sh
source ./scripts/setup.sh
source LCG_$LCG_VERSION/INSTALL/thisostap.sh
For the latest tag check the page https://github.com/OstapHEP/ostap/releases To update the package to latest version use following command:
git pull origin <latest tag>
or to get the head version use:
git pull origin master
We also provided Dockerfile to build the OstapHep image. You can run Ostap interactively using the command line or via Docker Desktop which is available for MacOS and Windows. To create the docker image from the Ostap directory run:
sudo docker build --network host -t <dockerID>/ostaphep:latest .
Run the image iteractively
sudo docker run -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix -v ${WORKDIR_PATH}/work_dir:/work_dir -it <dockerID>/ostaphep:latest
To know more about docker, please check the documentation: https://docs.docker.com/.
OstapHep is now available on the conda-forge channel https://github.com/conda-forge/ostaphep-feedstock. You can get ostap with conda using the following steps:
Install mininconda
wget http://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh
sh Miniconda3-latest-Linux-x86_64.sh
Set the conda environments
source path-to-miniconda/etc/profile.d/conda.sh
Add the conda-forge to your channels
conda config --add channels conda-forge
Check which versions are available
conda search ostaphep --channel conda-forge
Create an environment with a specific version of python
conda create --name ostap-env ostaphep python=3.7
To activate or deactivate the ostap environment use the following command
conda activate ostap-env
conda deactivate
To get the latest version of the Ostap package:
conda -n ostap-env install ostaphep=version
The list of available version you can find here. To know more about conda-forge, please visit conda page.
Additionally you can install the master version of the Ostap package using the dependancy packages which are also availible on the conda:
Set the conda environments
source path-to-miniconda/etc/profile.d/conda.sh
Add the conda-forge to your channels
conda config --add channels conda-forge
Create an environment with a requarement dependancies:
conda create -n ostap-req-env root_base root-binaries root-dependencies gsl future configparser numpy scipy pathos dill multiprocess ppft terminaltables binutils-meta c-compiler compilers cxx-compiler fortran-compiler python ipython cmake
Activate the environment with requarement packages:
conda activate ostap-req-env
Clone and build Ostap package:
git clone git://github.com/OstapHEP/ostap.git
cd ostap
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=<INSTALL_DIRECTORY>
make -j8
make install
source <INSTALL_DIRECTORY>/thisostap.sh
Note that the latest command should be used every time when the ostap-req-env are activated again.
The Ostap installation using the SWAN CERN service is described here.
