[Python] ValueError: RDD is empty-- Pyspark (Windows Standalone)

I am trying to create an RDD but spark not creating it, throwing back error, pasted below;

data = records.map(lambda r: LabeledPoint(extract_label(r), extract_features(r)))
first_point = data.first()

Py4JJavaError Traceback (most recent call last)
<ipython-input-19-d713906000f8> in <module>()
----> 1 first_point = data.first()
2 print "Raw data: " + str(first[2:])
3 print "Label: " + str(first_point.label)
4 print "Linear Model feature vector:\n" + str(first_point.features)
5 print "Linear Model feature vector length: " + str(len (first_point.features))

C:\spark\python\pyspark\rdd.pyc in first(self)
1313 ValueError: RDD is empty
1314 """
-> 1315 rs = self.take(1)
1316 if rs:
1317 return rs[0]

C:\spark\python\pyspark\rdd.pyc in take(self, num)
1295
1296 p = range(partsScanned, min(partsScanned + numPartsToTry, totalParts))
-> 1297 res = self.context.runJob(self, takeUpToNumLeft, p)..................


Any help will be greatly appreciated.

Thank you, Innocent
