The same error here. anyone got the solutions?
@AndelFeng @Shu882 @ch01ca @fly2fire I found a fix.
Problem
Assuming we are using backtrader and ibpy2, there is already a clue...
So in our current state we cannot find IBStores which we can confirm it doesn't exist by using dir
in python to print the properties of bt.stores:
['VCStore', 'VChartFile', 'builtins', 'cached', 'doc', 'file', 'loader', 'name', 'package', 'path', 'spec', 'absolute_import', 'division', 'ibstore', 'print_function', 'unicode_literals', 'vchartfile', 'vcstore']
Since we know ibpy2 is python2 (trailing 2 in package name being a giveaway) it's reasonable to guess that the reason this doesn't work is some mismatch between this python2 thing (and its assumptions about how things work) and the python3 backtrader.
Solution
So the way to test that guess is to port the whole of ibpy2 to python3:
find x/lib/python3.9/site-packages/ib/ -name '*.py' -exec 2to3 -w {} \;
(x in this is the name of the virtual env I installed it under)
If we check the properties of bt.stores again IBStores
shows up:
['IBStore', 'VCStore', 'VChartFile', 'builtins', 'cached', 'doc', 'file', 'loader', 'name', 'package', 'path', 'spec', 'absolute_import', 'division', 'ibstore', 'print_function', 'unicode_literals', 'vchartfile', 'vcstore']
@Jamesfryer1998
Does it work now? I wonder how to fix it in my Windows PC. Thanks a lot:)
I am the same. I am using Conda, I have backtrader and IBPY2 successfully installed and I still get this error. Any other solutions?
