--------------------------------------
Hi wangwei,
Thanks for the link to understanding more about shared libraries! I've read it.
Just after the fix has been pushed, I went to try installing `singa-cpu=1.2.0`
again, using the same Dockerfile as above. However, the _exact_ same error as
_above_ occurs.
Below is my `conda list`:

I wanted to verify that `singa-cpu=1.2.0` gives me the same error on my MacOS
natively, but I failed to install it as it seems like `singa-cpu=1.2.0` for OSX
is not out...? (https://conda.anaconda.org/nusdbsystem/osx-64)
Let me know if there's something wrong with what I am doing.
A note that for Rafiki, it is no longer a requirement to upgrade `protobuf` to
3.6.1 (ref. to [SINGA-396]). This is because we are no longer pre-installing
both Tensorflow and Singa on the base worker image. However, if a model
developer specifies the installation of both Tensorflow and Singa <=1.1.1, one
of these might not work due to the possible version conflict in `protobuf`.
