Github user Leemoonsoo commented on the issue: https://github.com/apache/zeppelin/pull/2106 Tested `%python.conda` and `%python.pandasql` and it works well. Could you restore PythonDockerInterpreter.java and PythonDockerInterpreterTest.java for `%python.docker` as well? To make it work, i think we need to let docker container mount directory that py4j exists using -v option, and then set PYTHONPATH env variable to load py4j library using -e option. So this line ```java setPythonCommand("docker run -i --rm " + image + " python -iu"); ``` can be updated to something like ```java String py4jDir = ZEPPELIN_HOME + "/interpreter/python"; String py4jFile = "py4j-{version}.zip"; // read directory py4jDir and get file starts with py4j setPythonCommand("docker run -i --rm -v " + py4jDir + ":/zeppelin_python -e /zeppelin_python/" + py4jFile + " " + image + " python -iu"); ```
