TypeError: 'JavaPackage' object is not callable, when spark-commit xgboost_example

[00-Luoshu]

• env:

  • python:3.7
  • java:1.8
  • spark:3.1.2

• The doc and code comes from https://github.com/intel-analytics/BigDL/tree/main/python/dllib/examples/nnframes/xgboost https://github.com/intel-analytics/BigDL/blob/main/python/dllib/examples/nnframes/xgboost/xgboost_example.py

• My spark-submit command:

  /home/intel/spark-3.1.2-bin-hadoop2.7/bin/spark-submit \
  --master "local[4]" \
  --driver-memory 2g \
  --executor-memory 2g \
  local:///home/zhangyu/BigDL/python/dllib/examples/nnframes/xgboost/xgboost_example.py --file-path data/sample.csv 

• And error message

  TypeError: 'JavaPackage' object is not callable

And I didnot  downloaded Analytics Zoo zip package, just use spark-submit
How can I fix this?

Reason:

Lack of BigDL jar files in your script, JavaPackage happens because python cannot find the java class.

Solutions:

Use spark-submit

1. Download bigdl dllib jars file from BigDL DLLib Jars.
2. Submit following the script below:

/home/intel/spark-3.1.2-bin-hadoop2.7/bin/spark-submit \
  --master "local[4]" \
  --driver-memory 2g \
  --executor-memory 2g \
  --jars /path/to/bigdl-dllib-spark_${SPARK_VERSION}-jar-with-dependencies.jar \
  local:///home/zhangyu/BigDL/python/dllib/examples/nnframes/xgboost/xgboost_example.py --file-path data/Boston_Housing.csv

Use spark-submit-with-bigdl

Submit following the script below:

/home/zhangyu/BigDL/scripts/spark-submit-with-bigdl \
   --master ${MASTER} \
   --driver-memory 2g \
   --executor-memory 2g \
   local:///home/zhangyu/BigDL/python/dllib/examples/nnframes/xgboost/xgboost_example.py --file-path data/Boston_Housing.csv 

NOTE:

• We have migrated Analytics-zoo to BigDL, you only need to download BigDL packages (not Analytics-zoo) if needed.
• It's recommended for you to use Boston_Housing.csv instead of sample.csv.
