Based on the error message above, it seems the Java process not started successfully. Can you please check if the java command is in PATH or set the correct JAVA_HOME?

[FRMer3737]

I also encountered this issue. Have you resolved it?

[scorebot]

@FRMer3737 Can you please provide the following info? OS, Python version, Java version, and pypmml vresion

[FRMer3737]

@scorebot thanks for your rapid answer. python3.12.4；Java 1.8.0_333；pypmml 1.5.2； print(os.path.exists(r'br_fpd_model_2024.pmml')) is true

[scorebot]

@FRMer3737 What's your OS? Is the java command in PATH or setting the correct JAVA_HOME?

[FRMer3737]

sorry，my os is windows and setting the correct JAVA_HOME

The root cause is Java 1.8 which doesn't support the option --add-exports=java.base/jdk.internal.math=ALL-UNNAMEDthat was added from pypmml>=1.0, the workaround is to upgrade your java to a new version, for example, Java 11. Actually, the latest pypmml doesn't depend on the option anymore, I will remove it in the next version soon

[FRMer3737]

Thanks sooooooo much. I'll try it.
