The conda package specification includes the package name (i.e. singa), version and build string (could be very long).
To install a certain SINGA package we run
conda install -c nusdbsystem singa=<version>=<build string>
It is inconvenient to type all 3 parts when running the installation commands.
The meta.yml file in this folder is to create a conda package `singa-dist` as
an alias of one specific SINGA package.
It does nothing except creating a dummy conda package that depends on one real
gpu version SINGA package. For example, the following line in meta.yml indicates
that singa-gpu depends on SINGA with version 1.1.1, python version=3.6, cuda version=9,
cudnn version = 7.1.2, nccl version = 2.4.8.1, and mpich version = 3.3.2
- singa 1.1.1 py36_cuda9.0_cudnn7.1.2_nccl2.4.8.1_mpich3.3.2
Therefore, when we run
conda install -c nusdbsystem singa-dist
The dependent SINGA package will be installed.
By default, singa-dist depends on the latest SINGA (py3.6) on the latest cuda (and cudnn),
as well as the distributed computing libraries nccl and mpich.
When we have a new SINGA version available, we need to update the meta.yml file to
change the dependency.
To build this package and upload it
conda config --add channels nusdbsystem
conda-build . --python 3.6
anaconda -t $ANACONDA_UPLOAD_TOKEN upload -u nusdbsystem -l main <path to the singa-dist package>
where $ANACONDA_UPLOAD_TOKEN is the upload token associated with nusdbsystem account on anaconda cloud.
