Ngin Yun Chuan created SINGA-396:
------------------------------------
Summary: Upgrade `protobuf` to 3.6.1 to match Tensorflow's
Key: SINGA-396
URL: https://issues.apache.org/jira/browse/SINGA-396
Project: Singa
Issue Type: Improvement
Components: PySINGA
Reporter: Ngin Yun Chuan
`singa-cpu==1.1.1` depends on `protobuf==3.2.0`, but `tensorflow==1.10.1`
depends on `protobuf==3.6.1`. When Tensorflow is installed with Singa on the
same image, such an error occurs when importing `tensorflow`:

```
This error seems to occur due to an incompatible version of `protobuf`:

Here is a Dockerfile that reproduces the error:
```
FROM ubuntu:16.04
RUN apt-get update && apt-get -y upgrade
# Install conda with pip and python 3.6

RUN pip install tensorflow==1.10.1
