code:
import (
"fmt"
"github.com/dmitryikh/leaves"
)
func main() {
// 1. Read model
useTransformation := true
model, err := leaves.LGEnsembleFromFile("lightgbm_model.txt", useTransformation)
if err != nil {
fmt.Println(err)
panic(err)
}
}
go build lgbuse.go
, and then report an error:
only version=v2 is supported
panic: only version=v2 is supported
goroutine 1 [running]:
main.main()
lgbuse.go:14 +0x246
exit status 2
The line of code that cause probles:
model, err := leaves.LGEnsembleFromFile("lightgbm_model.txt", useTransformation)
How can I solve this problem?

I'm using the latest version as for now github.com/dmitryikh/leaves v0.0.0-20200503205002-939b6fa631dd
and it works with v3 LightGBM model fine.
