Problem when running webcam client/server demo

[puddinord]

Hi, @jcjohnson
I followed your instruction to run the client/server webcam demo. When I am running python webcam/server.py, the command was stuck there and it returned

loading checkpoint from data/models/densecap/densecap-pretrained-vgg16.t7
done loading checkpoint
Warning: cudnn.convert does not work with nngraph yet. Ignoring nn.gModule

I know the warning can be ignored safely, but I don't know the reason why the loading process was stuck(it can't run the next command)after it said done loading checkpoint.

And then I tried to run python webcam/server.py, I also have the issue

Traceback (most recent call last):
File "webcam/server.py", line 7, in
from flask import Flask, request
ImportError: No module named flask
zhangcheng@zhangcheng-To-be-filled-by-O-E-M:~/densecap$ sudo apt-get flask
[sudo] password for zhangcheng:
E: Invalid operation flask

I appreciate your help!

You need to install flask, and some other dependencies as it suggests. Following are the packages I had to install apart from the requirements the repo suggested.
pip install flask flask-cors flask_restful tornado

Hi all, @sampathchanda @puddinord,
I installed the requirements mentioned in the requirement file, but it won't run and i couldn't find any other instructions to run the Client/ server mode.
Thanks in Advance
