panda-client
The panda-client package includes python modules and command-line tools to allow end-users to submit/manage their analysis on the PanDA system. This package is supposed to be used by end-users as functionality is simplified and limited. System administrators or developers should refer to API reference.
Installation
panda-client works either python 2 and 3, and is self-contained so that you don’t have to install an external package or software. The installation step can be skipped if panda-client has been centrally installed like ATLAS. Otherwise, simply run the following pip command in a virtual environment to install all python modules, command-line tools and configuration files:
pip install panda-client
If you install panda-client in JupyterLab,
pip install panda-client[jupyter]
will install extra packages in addition to panda-client.
Setup
The setup file panda_setup.(c)sh
is automatically generated under $VIRTUAL_ENV/etc/panda when panda-client
is installed via pip. You need to source the file to setup the required environment variables before using the
python modules and command-line tools. It is good to define a shell function to source the setup file as shown
in the ATLAS users tag.
source $VIRTUAL_ENV/etc/panda/panda_setup.sh
export ATLAS_LOCAL_ROOT_BASE=/cvmfs/atlas.cern.ch/repo/ATLASLocalRootBase
setupATLAS
lsetup panda
The following environment variables need to change if necessary.
