Questions[eps](ubuntu)

I have installed an open source python platform for data analysis called YT and was trying to run a python script with the following imports:

import yt
import numpy as np
import yt.visualization.eps_writer as eps
from yt.data_objects.particle_filters import add_particle_filter
from matplotlib import pyplot as plt
plt.switch_backend('agg')

However, I get an error of not being able to find the module pyx:

> Traceback (most recent call last):   File "gasinflow.py", line 3, in
> <module>
>     import yt.visualization.eps_writer as eps   File "/home/samvad/anaconda3/lib/python3.6/site-packages/yt/visualization/eps_writer.py",
> line 16, in <module>
>     import pyx ModuleNotFoundError: No module named 'pyx'

Python version: 3.6 I have come across this being an issue with Cython not being installed but Cython-0.29.7 is installed too.

I have to modify only the text of an EPS file. I would like to do that without using programs such as inkscape, and I would rather modify the eps file opening it as a text file (for instance using gedit). Is there a way to do it?

Back in 8.04 and 10.04, GIMP could easily open WMF files, letting me work on them.

In 11.04, there was a regression (still not fixed!), and this would not work.

But at least there was a workaround. You could convert WMF files to EPS and work on them.

wmf2eps --wmf-fontdir=/usr/share/fonts/type1/gsfonts -o outputfile.eps inputfile.wmf

However, now we have 12.04, and not even the workaround works any more; it is unable to convert the file. There is no error message; it just fails with error code 1.

Despite Inkscapes claims to be a plausible solution (workaround) Inkscape simply opened the WMF image as a completely empty image, with no error message.

I need to work on WMF files quite urgently. Does anyone know what I can do, whether work-around or (preferably) a fix?
