ImportError: pyspark home needs to be added to PYTHONPATH

[ghost]

During execution of following simple code with Sparkit-Learn:

from splearn.svm import SparkLinearSVC
spark=SparkLinearSVC()

I get following error message:

ImportError: pyspark home needs to be added to PYTHONPATH.
export PYTHONPATH=$PYTHONPATH:$SPARK_HOME/python:../

In accordance with those anserws:

http://stackoverflow.com/questions/23256536/importing-pyspark-in-python-shell
I have added every possible configuration of those PYTHONPATHs to my .bashrc,but error is still occuring.

Currently my .bashrc paths looks like that:

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export PATH=$JAVA_HOME/bin:$PATH
export PATH=/home/123/anaconda2/bin:$PATH
export SPARK_HOME=/home/123/Downloads/spark-1.6.1-bin-hadoop2.6
export PATH=$SPARK_HOME/bin:$PATH
export PATH=$JAVA_HOME/jre/lib/amd64/server:$PATH
export PATH=$JAVA_HOME/jre/lib/amd64:$PATH
export PYTHONPATH=$SPARK_HOME/python/:$PYTHONPATH
export PYTHONPATH=$SPARK_HOME/python/lib/py4j-0.9-src.zip:$PYTHONPATH

Any possible solution? I am running this on Ubuntu 16.04,Pycharm and spark-1.6.1-bin-hadoop2.6

I will share you my .profile. Hope this helps:

# For a ipython notebook and pyspark integration
if which pyspark > /dev/null; then
    #/usr/local/Cellar/apache-spark/1.5.1
  export SPARK_HOME="/usr/local/Cellar/apache-spark/1.6.1/libexec/"
  export PYSPARK_SUBMIT_ARGS="--master local[2]"
fi

export SPARK_HOME="/usr/local/Cellar/apache-spark/1.6.1/libexec"
export PYTHONPATH=$SPARK_HOME/python3/:$PYTHONPATH
export PYTHONPATH=$SPARK_HOME/python3/lib/py4j-0.9-src.zip:$PYTHONPATH
#export PYSPARK_PYTHON=python3

Note that I am working with a Jupyter notebook:

In:
from splearn.svm import SparkLinearSVC
spark=SparkLinearSVC()

I do not get the same error message.
