KeyError in complete-opf-example.py

[RootChenLQ]

There is nan value in multistepBucketLikelihoods, when I use my own dataset, and set _NUM_RECORDS as 6000. The error is listed as below.

multistepBucketLikelihoods = {1: {499: 1.0}, 5: {499: nan, 501: 0.0}}
File "D:\ProgramData\PythonWorkspace\nupic\docs\examples\opf\test.py", line 52, in runHotgym fiveStepConfidence = allPredictions[5][fiveStep]
File "D:\ProgramData\PythonWorkspace\nupic\docs\examples\opf\test.py", line 65, in <module>
    results = runHotgym(_NUM_RECORDS)

Thank you for your Help.
