First of all thank you for creating and maintaining this great library.
Secondly I seem to be running into some issues when trying to create a PMML from following pipeline
SEVERE: Failed to parse PKL net.razorvine.pickle.InvalidOpcodeException: invalid pickle opcode: 248
JPMML-SkLearn depends on the Pyrolite library for low-level PKL file parsing functionality. Apparently, Pyrolite does not recognize Pickle protocol opcode 248 (hex 0xf8).
Could you give me pointers on where I might be looking to solve this error?
The stack trace of this exception points at method net.razorvine.pickle.Unpikcler#dispatch(short). You could try addinng a case statement for opcode 248 there, and collect more information about it (eg. which Scikit-Learn class, which class attribute, etc.). Then, try to factor a minimal reproducible example, and open a parallel issue with the Pyrolite project: https://github.com/irmen/Pyrolite/issues
I ran the code with python 3.4 and I have it confirmed working ! You are great man ! 👍
When running your debug pointer I noticed that all tree models are affected, but others not.
For now I'll use python 3.4 as a workaround and I'll close the Issue.
Hello,
First of all thank you for creating and maintaining this great library.
Secondly I seem to be running into some issues when trying to create a PMML from following pipeline
The respective errors are :
SEVERE: Failed to parse PKL net.razorvine.pickle.InvalidOpcodeException: invalid pickle opcode: 248
Versions are
The weird thing is that this code (using kmeans) generates the PMML correctly, so it might be something model specific
Run on windows 7 SP1 64bit
Could you give me pointers on where I might be looking to solve this error ?
Thanks in advance.
