These instructions are for the new Custom Block only, not for the legacy R or legacy Python blocks. For these blocks, please see the instructions at Setting up legacy R and Python blocks


Custom Block


Windows


In order for this block to execute Python or R based scripts, recent Python and R installations are required.


In case Python or R was installed in a custom location that cannot be automatically discovered by Omniscope, it is possible to set the path to the executable manually in the admin area. 

After installing python or R, you need to restart Omniscope for the changes to take effect.


Installing Python


Python can be downloaded from the Python website: https://www.python.org/downloads/.


Installing R


R can be downloaded from: https://cran.r-project.org/bin/windows/.





Linux

Installing Python


On debian distributions, or distributions supporting apt-get, copy and paste the following line into the command line and press Enter:


sudo apt-get install python2 python3 python-pip python3-pip


For systems that do not support apt-get, please open the package manager and look for an available python version. Alternatively python can be built from sources. The sources and help can be found on the Python website: https://www.python.org/downloads/.



Installing R


Linux users need to make sure the development package for libcurl and ssl/openssl is installed.


For Ubuntu, open the terminal, copy and paste the following line into the command line and press Enter:


sudo apt-get install r-base libcurl4-gnutls-dev libssl-dev libcurl4-openssl-dev


For different Linux distributions, please either open the package manager and look for an available R version, or download and install a package file from https://cran.r-project.org/bin/linux/.







Mac OS X
