missing matplotlib.pyplot when following object_detection tutorial

[glc12125]

I am trying to follow the tutorial for training the pet object detector on Object_detection official tutorial

I have followed all the steps and fired a training and evaluation job to Google cloud project, but I saw errors in the streaming logs saying:

"ImportError: No module named matplotlib.pyplot" around line 24 of "/root/.local/lib/python2.7/site-packages/object_detection/utils/visualization_utils.py"

I tried to modify the setup.py file under research folder to include matplotlib as a dependency, but it introduces another issue:

"in _import_module import(name) File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 42, in raise ImportError, str(msg) + ', please install the python-tk package' ImportError: No module named _tkinter, please install the python-tk package"

I noticed that python-tk is not a pip package and can only be installed via apt-get or installed from source in the cases of GCP(without root right).

I noticed that people have similar issues but the question on stackoverflow is not answered yet.

Is there anything missing here? Any help will be appreciated.

Please install pip and matplotlib. Thanks.

This question is better asked on StackOverflow since it is not a bug or feature request. There is also a larger community that reads questions there. Thanks!

That I agree, but if more than two people are having the same issue, I would update the tutorial to mention such prerequisite.

Hello, I am having the same issue. I have all the dependencies installed.
I am getting the following:

ps-replica-2

Hey @lozuwa , please see my update in #2739, where I updated with a workaround for this issue.
