如何在Spark中为python 3.5安装numpy和pandas？

Question

I am trying to run a linear regression in Spark using Python 3.5 instead of Python 2.7. So first I exported PYSPARK_PHTHON=python3. I received an error "No module named numpy". I tried to "pip install numpy" but pip doesn't recognize the setting PYSPARK_PYTHON. How to I ask pip to install numpy for 3.5? Thank you ...

$ export PYSPARK_PYTHON=python3

$ spark-submit linreg.py
....

Answer 1

So I don't actually see this as a spark question at all. It looks to me like you need help with environments. As the commenter mentioned you need to setup a python 3 environment, activate it, and then install numpy. Take a look at this for a little help on working with environments. After setting up a python3 environment you should activate it and then run pip install numpy or conda install numpy and you should be good to go.

If you are running job local you just need to upgrade pyspark

Homebrew: brew upgrade pyspark this should solve most of the dependencies.
