Stuck at Listening to Redis Channel

I'm trying to run an application modeled after the python script in the tutorial. Code is below:

```
from pcloudcv import PCloudCV
config_dict = {'input':'/home/katie/images','output':'/home/katie/output','exec':'VOCRelease5'}
path_to_config_file = '/home/katie/pcloudcv/pcloudcv/config.json'
login_required = True
pcv = PCloudCV(path_to_config_file, config_dict, login_required)
pcv.start()
```

config file looks like this:

```
{
"exec": "VOCRelease5",
"maxim": 500,
"config": [
{
"name": "VOCRelease5",
"path": "local: /home/katie/images",
"output": "/home/katie/output",
"params": {
"Models": "all"
}
}
]
}
```

When I run the script, I receive what is pasted below, and it just gets stuck there. Any direction on how to fix this? I honestly am not sure what is supposed to happen because the screenshots are broken images, so that could also be a good starting point.
