问题:

In my python application i am using the matplotlib.when i start running it throws me an error:

ImportError: No named '_tkinter', please install the python3-tk package

Then i have installed sudo apt-get install python-tk.It got works in localhost.But same app i am deploying into the google cloudPlatforms.But i am getting this error:

import _tkinter # If this fails your Python may not be configured for Tk ImportError: libBLT.2.5.so.8.6: cannot open shared object file: No such file or directory

How to install python-tk to Google cloudPlatforms.After deactivate the vitualenv also i have installed.It shows already the newest version.I have tried many things but it doesn't seems to work.The App throws 502 Bad Gateway.

Thanks in advance.

Use

matplotlib.use('agg')

right after importing matplotlib, to render matplotlib graphics in a headless environment. You can also set this as the default in your matplotlibrc file, or via the MPLBACKEND environment variable.

See the matplotlib docs for more details: https://matplotlib.org/faq/usage_faq.html#what-is-a-backend See also the page on using matplotlib in a web application.
