Cant plot symbols in pyqtgraph using Python 2.7.13

[Vedran Furtula]

Hi folks,
My pyqtgraph example library suddenly stopped working:

import pyqtgraph.examples
pyqtgraph.examples.run()

I get TypeError whichever example I try to run. it seems that plotting symbols is not longer supported. For instance this code:

import pyqtgraph as pg
pg.plot([0,1,2],[0,1,2], symbol='o')

will produce TypeError.
Somebody else with the same problem?

Please post the whole error message with the stack trace (for your code example). Without that we can just guess.

If you get the same error for all the built-in examples, the problem is probably more fundamental than just the symbols in the plots. Also check if the error always originates from the same position in the code, if you try to start different examples.
