python is not responding on ver.0.7.2

小野圭二
Hi,

This might be an old and popular issue, but i could not find the solution on Jira, mail archive and so on.
The python demo does not work.

[Env]:  CentOS 6.2  Python 2.6.6
         Zeppelin   0.7.2 netinst
                 beneath 'interpreter': jdbc,lib,md,python,shell,spark 
[notebook]: from demo
%python
import matplotlib.pyplot as plt
plt.plot([1,2,3])

Traceback (most recent call last):
File "/tmp/zeppelin_python-2865335277309763273.py", line 20, in <module>
from py4j.java_gateway import java_import, JavaGateway, GatewayClient
ImportError: No module named py4j.java_gateway
Traceback (most recent call last):
File "/tmp/zeppelin_python-2865335277309763273.py", line 20, in <module>
from py4j.java_gateway import java_import, JavaGateway, GatewayClient
ImportError: No module named py4j.java_gateway

python is not responding


Any advice would be appreciated.

Hi, I haven't used net installation version. But it seems that u need to install `py4j` python library as the error says

No module named py4j.java_gateway

You can do easily `
pip install py4j` with your python bin which related to the python interpreter in Zeppelin.

Hi Park,

Thank you for response to this.
I thought that was caused in your pointing at the first, but the py4j had already been installed in it.
I guessed the issue of depending on PATH or CLASSPATH environment parameters as well.
They were not.

Indeed, it worked fine on other our Linux machine.
I am not sure yet what was wrong on the first Linux that was my best dev-machine. :-b

Now i have been starting it to be clean-install on the new environment.
I would like to share this issue if it will be clear.
