Install success but has a keyerror when import

#1

I installed the zipline but there is a key error when I import zipline.
I wonder if anyone could help.

Good day,

I got the exact same error message yesterday when I was just about to ingest data

Today when trying to import Zipline, I got the error again both on Python v3.7 and v3.8.

I think there is an issue with the package itself that its developers must resolve who are familiar with the modules and code that comprise the library.

It is the first time that I am unable to resolve an error message in my code using Zipline.

Stefan should be able to figure out what the issue is and suggest a solution.

Regards

Thanks for your reply. When I looked at the error message, I saw the country code has an error. Then I could find any related material on how to fix this. Hope someone could figure it out

Here is the solution I found on Github:

ISO3166 has been updated, “Turkey” changed to “Türkiye”. This causes various things to break that relied on “TURKEY”, setting ISO==2.02 works. This is not necessarily a zipline problem, but can cause issues for fresh installs. Posting here in case anyone else has the problem. pip install iso3166==2.02 solves it

2.1.0 - July 11, 2022
-Updated entries
—“Turkey” changed to “Türkiye”

Update iso3166 to a newer version after Zipline installation

!pip install iso3166==2.0.2

The import should work:
