Hi @dxq0126, @MilanHajicek, and @54mu3l - could you please tell me what project you're seeing this issue in?
Hi David,
It goes about the GitHubIssueClassification
Have a look at the error details when running in the VS2019.

Hi @dxq0126, @MilanHajicek, and @54mu3l - could you please tell me what project you're seeing this issue in?
the project is at machine-learning/tutorials/GitHubIssueClassification/GitHubIssueClassification
and the environment is .net core 2.1 Microsoft.ML(1.5.1)
Hi @dxq0126, @MilanHajicek, and @54mu3l - could you please tell me what project you're seeing this issue in?
same project as mentioned above
with .net core 3.1 Microsoft.ML (1.5.1) VS2019
Hello, the same error here using: .net core 3.1 Microsoft.ML 1.5.1 VS2019 16.6.5
The same code is working with the Microsoft.ML 1.5.2-29219-1 from the daily NuGet feed
