Background

General programming environments for so-called neural or deep learning (DL) are a prerequisite to much current NLP research, somewhat analogous to compilers or core libraries (like Boost or ICU). These frameworks are not in principle discipline-specific and will often be difficult to install in user space (i.e. without administrator privileges). Thus, general DL support should be provided at the system level (not on a per-project basis), and NLPL will seek to work with the system administrators to make sure that (a) relevant frameworks are available (in all relevant versions, both for CPU and GPU usage) and (b) that system-wide installations provide at least some degree of parallelism between the systems available to NLPL users. These are no small ambitions :-).

Taito

It appears that CSC has started to actively support deep learning, possibly at least in part in response to requests from NLPL users. In early 2018, the following packages are available on Taito (although some do not seem easily discoverable via the module command):

DyNet 2.0 and 2.0.1, apparently both for CPU and GPU nodes

TensorFlow many versions, from 0.11 through 1.5.0; seemingly only installed for GPU nodes, though page provides instructions for user-level installation of CPU-only version.

ML Bundle Python 2.x and 3.x installations with multiple DL frameworks included, notably MxNet, PyTorch, Theano, and TensorFlow. No version information available for individual DL frameworks, and version scheme for the bundle at large seems to follow Python versions. Seemingly only available on GPU nodes. Potentially troubling announcement that “packages in the Mlpython environments are updated periodically.”

Abel

In early 2018, the two system-wide installations of DL frameworks on Abel appear to reflect requests from NLPL users.

DyNet no version number specified, but apparently 2.0 (dynet.__version__); may be CPU-only; Singularity container

TensorFlow no version number specified, but apparently 1.0.1 (tensorflow.__version__); supports both CPU and GPU nodes; Singularity container.

Installation inside of Singularity containers on Abel limits interoperability, as there is no straightforward way of ‘mixing and matching’ with other modules.

Vision

The ideal situation, from the NLPL point of view, would be (a) availability and support for all relevant DL frameworks, in (b) multiple, clearly discernible versions as the frameworks involve. It should be possible to (c) combine multiple frameworks with each other (the Uppsala parser, for example, internally both requires DyNet and TensorFlow, each in a particular version). Installations and usage patterns on Abel and Taito should be (d) uniform to the highest degree possible across the two systems.
