import librosa in google cloud ml

Question

I am running Google cloud ML and when I try to import librosa I get the error:

ImportError: No module named _tkinter, please install the python-tk pa

Answer 1

You need to install the python-tk package by modifying your setup.py to pull it in as a dependency. Since it is an apt package you can modify your setup.py file to install it via apt. Here's what a sample setup.py file might look like.

import logging
import subprocess
from setuptools import find_packages
from setuptools import setup
from setuptools.command.install import install

# Some custom command to run during setup. Typically, these commands will
# include steps to install non-Python packages.
#
# First, note that there is no need to use the sudo command because the setup
# script runs with appropriate access.
# Second, if apt-get tool is used then the first command needs to be 'apt-get
# update' so the tool refreshes itself and initializes links to download
# repositories.  Without this initial step the other apt-get install commands
# will fail with package not found errors. Note also --assume-yes option which
# shortcuts the interactive confirmation.
#
# The output of custom commands (including failures) will be logged.


class CustomCommands(install):
  """A setuptools Command class able to run arbitrary commands."""

  def RunCustomCommand(self, command_list):
    print 'Running command: %s' % command_list
    p = subprocess.Popen(
        command_list,
        stdin=subprocess.PIPE,
        stdout=subprocess.PIPE,
        stderr=subprocess.STDOUT)
    # Can use communicate(input='y\n'.encode()) if the command run requires
    # some confirmation.
    stdout_data, _ = p.communicate()
    print 'Command output: %s' % stdout_data
    logging.info('Log command output: %s', stdout_data)
    if p.returncode != 0:
      raise RuntimeError('Command %s failed: exit code: %s' %
                         (command_list, p.returncode))

  def run(self):
    self.RunCustomCommand(['apt-get', 'update'])
    self.RunCustomCommand(
          ['sudo', 'apt-get', 'install', '-y', 'python-tk'])

    install.run(self)
