| 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. |
