When I stop the script manually in PyCharm, process finished with exit code 137. But I didn't stop the script. Still got the exit code 137. What's the problem?
Python version is 3.6, process finished when running xgboost.train() method.

Exit code 137 means that your process was killed by (signal 9) SIGKILL . In the case you manually stopped it - there's your answer.
If you didn't manually stop the script and still got this error code, then the script was killed by your OS. In most of the cases, it is caused by excessive memory usage.

I had the same error. In my case was related to excessive memory usage. Solved after reseting/cleaning my cache data adding the following code for every variable that will not be used anymore :
MyVariableName = None

It's not always a memory issue. In my case subprocess.Popen was utilized and it was throwing the error as 137 which looks like signalKILL and the cause is definitely not the memory utilization, because during the runtime it was hardly using 1% of memory use. This seems to be a permission issue after more investigation. I simply moved the scripts from /home/ubuntu to the root directory.

{In my experience}
this is because of Memory issue. When I try to train ml model using sklearn fit with full data set , it abruptly breaks and gives whereas with small data it works fine.
Process finished with exit code 137 (interrupted by signal 9: SIGKILL) Interestingly this is not caught in Exception block either

My python process get killed with the 137 error code because my Docker for Windows memory limit was set too low.
