Example Code is not working about gryphon

[garethdmm]

Hey @Vikhyat05, if I understand correctly, the screenshot you've shown is expected behaviour from ipython. That import that is failing is for a .pyx (cython) file, so you need to import the cython importer logic before it'll work. This is the code you need to run in order to import cython files:

import pyximport

pyximport.install()

Was there another issue you were seeing when you run that file from the strategy engine? The demo code might be slightly out of date, would be good to know.

Thanks for your reply
Now when i tried to run on the command line there was and import error.

Also please let me know that to run this sample strategy is it necesary for me to provide the
API key , secerets and passphrase.

Ok there are a couple things going on here.

First, gryphon-exec strategy takes a path to a strategy file from the current working directory, and the path that you're using looks like it's wrong. Your current working directory is 'strategies' and you create the strategy in that folder, but then run gryphon-exec strategy strategies/arb.py. This fails because that path isn't valid. In the way you have set it up the command should just be gryphon-exec strategy arb.py.

Second, the currently uploaded version of gryphon only supports strategy files with the .pyx suffix, not .py. There is a fix out for this in a branch right now but for now you should use arb.pyx not arb.py.

It looks like you're a couple steps away from being able to run this strategy, if you join the gryphon slack and join the #installation channel, I or someone else I'm sure would be happy to help you, and it would probably be faster than doing it through this issue.

Thanks a lot, @garethdmm for help. Now the code is working fine. Yeah, I have joined the slack group too.
Now you can please close the issue.
