ImportError: No module named Qwt5

[Guy]

Hello,

i just installed the guiqwt2.3.1 and have a problem to run the basic following script:

  import guiqwt.pyplot as plt # only this line has changed!
  import numpy as np
  x = np.linspace(-10, 10)
  plt.plot(x, x**2, 'r+')
  plt.show()

after  trying to Run, i got the error message:

       from PyQt4.Qwt5 import (QwtPlot, QwtSymbol, QwtLinearScaleEngine,
  ImportError: No module named Qwt5

how can i fix it?

Thanks,
Guy

You need to install the PyQwt5 module.
How to do this depends on your platform. For example, on debian/ubuntu,
it is :

sudo aptitude install python-qwt5-qt4

On windows I would use PythonXY to get everything installed (including
guiqwt itself)

https://code.google.com/p/pythonxy/

I hope this helps

Hi,

You just need to install PyQwt5 which is one of guiqwt dependencies among other libraries (PyQt, guidata, NumPy, …).
