Until recently, data scientists had only a handful of tools to work with, but today there is a robust ecosystem of frameworks and hardware runtimes. While this growing toolbox is extremely useful, each framework has the potential to become a silo, lacking interoperability. Supporting interoperability requires customization, and reimplementing models for movement between frameworks can slow development by weeks or months. The Open Neural Network Exchange (ONNX) format was...

In our previous post, we highlighted OML4Py’s Embedded Python Execution using the Python API. In this post, I’ll introduce the REST API for invoking Python functions to be run in Python engines spawned and managed by the database environment. Introduction Using any client that supports REST calls, such as cURL or Postman, you can invoke scripts in the OML4Py script repository from a REST client. The OML4Py REST API includes endpoints for listing and running user-defined...

Background With the release of Oracle R Distribution 3.6.1, we’ve rerun the R-Benchmark-25 script to highlight the current performance gains using dynamically linked Intel Math Kernel Library with Oracle R Distribution. Open source R's internal BLAS library was created when multi-core machines were uncommon. Hence by design, R is single-threaded and will only use one processor of a multi-core machine when doing calculations. Several parallel processing packages for R exist that...

Oracle R Distribution (ORD) version 3.6.1 is now released on Oracle Linux 7 yum and Open Source Software channels. This update, code named "Action of the Toes", is a maintenance release for the R-3.6.x series, and a major update to the R Language engine since the release of Oracle R Distribution 3.4.4.  This update brings new features, user-visible changes, and bug fixes. Highlights include: improvements to random number generation, an updated serialization format, support...

For users who want to connect to Oracle Autonomous Database (ADB) from an R client today, use the ROracle package. An ROracle client can easily be configured to create a database connection. To establish the connection, both an R and ROracle installation are required, along with the Oracle Database Client and an Oracle Wallet. Installation R and ROracle Either open source R or Oracle R Distribution can be used to establish a connection to ADB.  When installing open source R,...

Oracle R Distribution version 3.4.4 is now released on Oracle Linux 6 and Linux 7 yum channels. This update, code named "Someone to Lean On", is a maintenance release for the R-3.4.x series, but a major update to the R Language engine since the release of Oracle R Distribution 3.3.0. R Engine Updates The R-3.4.x series brings several major changes aimed at improving the performance of R programs. The Just-In-Time (JIT) byte-code compiler is now enabled by default. R will...

When installing R packages on Linux 6, a common issue is that the native GCC compiler is not sufficient for building C++ 2011 standard code.  In some cases, the R package developer will identify the C++11 requirement on the package's CRAN site or in the compilation log. Or, the build log may simply return errors indicating the C++11 support is not available:   cc1plus: error: unrecognized command line option "-std=c++11" To work around this issue, you can install and enable...

The R ecosystem offers numerous packages for performing data analysis. Currently, the CRAN package repository features over 14,000 available packages! A key benefit to using R is the endless support it gets from statisticians, developers, and data science experts around the world. The CRAN repository offers R packages in Linux source format, or as binaries for Windows and MacOS.  If you are installing R packages on another Operating System such as Solaris, you will need to...

When simultaneously learning a new tool and working toward a deliverable deadline, getting timely help with technical problems is critical. If you work with R/Oracle R Distribution, Oracle R Enterprise, or Oracle R Advanced Analytics for Hadoop and need to engage support resources, we recommend doing everything you can to expedite a solution to the problem you are facing. The following tips on working effectively with support will enable more efficient communication, leading...
