------------------------------
Summary: pre-trained param checkpoint version reset problem
Key: SINGA-107
URL: https://issues.apache.org/jira/browse/SINGA-107
Project: Singa
Issue Type: Bug
Reporter: ZHAOJING
When loading pre-training params, this version of code will reset the param
version to 0. Then if this param is used again in another model, then the
version number will become 0 and this param is not regarded as pre-training
param thus will require initialization, which will incur problems.
Present solution is to load this param more than one time, so that the latter
loading can override the first loading, and the version number will not be 0
and this param is still regarded as pre-training param.
For example, in rbm3.conf, we write like:
checkpoint_path: "examples/rbm/rbm2/checkpoint/step6000-worker0"
checkpoint_path: "examples/rbm/rbm1/checkpoint/step6000-worker0"
in order to load w1 and b12 twice.
