Problem in building a docker image with pyspark lib

问题

I'm trying to build a docker image using s2i and Jenkins. I have the following dependencies in the requirement.txt file

scikit-learn==0.21.2
scipy==0.18.1
pandas==0.24.2
seldon-core==0.3.0
pypandoc
pyspark==2.4.1

But my build process fails when it tries to install pyspark with the following error message

Downloading https://repo.company.com/repository/pypi-all/packages/f2/64/a1df4440483df47381bbbf6a03119ef66515cf2e1a766d9369811575454b/pyspark-2.4.1.tar.gz (215.7MB)

although I have listed pypandoc before pyspark in the requirments.txt file, but it looks like when it's installing pyspark, pypandoc is not installed yet, which is a dependency. What's the problem?

回答1:

I passed this error by executing:

pip install pypandoc

before installing pyspark. I tried a lot use pypandoc==1.4 in requirements.txt but it doesn't work.

In that sources people using same way: https://hub.docker.com/r/takaomag/test-0/dockerfile https://www.ibm.com/support/knowledgecenter/el/SSWTQQ_2.0.3/install/t_si_pythonpackagesoffline.html unable to install pyspark
