pmml generation fails about sklearn2pmml

[vruusmann]

Python's subprocess.check_call(cmd) suppresses the original Java exception. So, this sklearn2pmml error indicates that there's something wrong, but not what exactly.

You can see the original Java exception if you re-try the conversion of preserved pickle files using JPMML-SkLearn command-line application:

java -jar target/converter-executable-1.1-SNAPSHOT.jar --pkl-mapper-input <path to mapper pickle file> --pkl-estimator-input <path to estimator pickle file> --pmml-output <pmml file>

Paste the output of the above command here. Alternatively, you can send these preserved pickle files to my e-mail (assuming they do not contain overly sensitive information) and I will conduct the investigation on my own.

I will get in touch with you through email.

Thanks a lot!
