can't find file flow_20160314_20160314.checkpoint

[myvu11]

Hi
Under the section Prepare input 2. Flow aggregation, I've tried to run:

python flow.py -d 20160314 -i 15 >> log/flow0314.log

The file "flow_20160314_20160314.checkpoint" can't be found. Supposely it shoud be in the "data" directory but is not.
Could you take a look at it?

I had the same problem when running the file, have you solved it?

Hi hi, checkpoint is used in the case when the running of flow.py file is interrupted and needs to be rerun. Checkpoint file should be generated the first time flow.py runs. (The code was tested with dummy data before being uploaded.) if it is not generated, one possibility is that the data folder is not writable - please check the access to the data folder. Or else, to get around this issue, you may try commenting out all code related to checkpoint, and let flow.py run only once.
