module 'backtrader.stores' has no attribute 'IBStore'

yukking

ibpy2 is installed and it can import.

But when I test this code:

import ib
import backtrader as bt
store = bt.stores.IBStore(port=7497)'

I get the error:

AttributeError: module 'backtrader.stores' has no attribute 'IBStore'

Can someone help me?

You didnt import the module ibstore. Try e.g.

import backtrader.stores.ibstore as ibstore
store = ibstore.IBStore(port=7497)

Thx@vbs, I tried it but got the same error.

AttributeError: module 'backtrader.stores.ibstore' has no attribute 'IBStore'

@vbs said in module 'backtrader.stores' has no attribute 'IBStore':

import backtrader.stores.ibstore

Hm please open a python shell and do this:

import backtrader.stores.ibstore

and then

dir(backtrader.stores.ibstore)

and post the output.

python shell output

>>> import backtrader.stores.ibstore
>>> dir(backtrader.stores.ibstore)

IBStore is clearly in there, I can see it :P

And you are sure that this does not work now? Well, it has to work

store = backtrader.stores.ibstore.IBStore(port=7497)

I think I found the problem, but I don't know how to fix it.
When I used the python shell, it didn't report an error.
But when I use python script, it gives an error.

AttributeError: module 'backtrader.stores' has no attribute 'ibstore'

Finally, I found the problem and solved it.
My file name is ib.py, which is the same as the module name of ibpy.
Anyway, thank you all.
