Can't run any Python script
Hello,
I'm trying to add a Python visual in a report. After adding a fake value to the python viz, I wrote the following script
matplotlib.pyplot.plot([1,2,3,4], [5,6,7,8])
matplotlib.pyplot.ylabel('Some numberts')
matplotlib.pyplot.show()But everytime the following error pops up.
What goes wrong? Is it the fact that a comma "," is the standard for a decimal on my system in stead of a point "."?
kind regards,
Paul
Hi Dale,
I've found out what the problem is and there is a work-around. I have a Dutch version of Windows. Comma-decimal is standard on my system. In the settings i've chaged it to point-decimal. But it would be nice if the python-visual works the same as the R-visual. When I use the R-visual I don't have the problem with comma- or point decima.
The error that I have is in row 6 of the script. And that is a row that python automatically generates when I open the python-visual.
I use the latest version of anaconda.
Regards,
Paul

In Python, a comma separates arguments in a list of arguments. Float literals are always written with a decimal point.
In this case you are sending figsize = (4, ERROR, 3, 78427344733141)
In this case I am saying ERROR because number literals in python that begin with 0 should be expressed in octal (base 8) and the two 8s in the number make it an invalid literal, which is what the compiler is complaining about.
You need to rewrite that with decimal points.
If you need to conver between decimal commas and decimal points, have a look at the locale module in python.
I work on a dutch version of Windows 7. We use comma decimals in stead of point decimals. This gives me the following error when I run a very simple python script in the PBI Python visual:
I also posted this issue on the desktop forum (see Forum-topic).
I think it's a bug, because when I use the R-visual in power bi I don't have the issue with comma decimals, because the R-visual uses standard the point decimal.
I hope this is the correct place to address this kind of issues/bugs.

Hi Paul,
Everything seems fine.
1 Can you share your file?

Hi all!
The another possible solution (workaround) is to change in function figManager parametr figsize.
Try
figsize=rcParams['figure.figsize']
instead
figsize=figsize
figManager = new_figure_manager(num, figsize=rcParams['figure.figsize'], #figsize=figsize, dpi=dpi, facecolor=facecolor, edgecolor=edgecolor, frameon=frameon, FigureClass=FigureClass, **kwargs)
in the pyplot.py
In actual version of Anaconda strings 542-549Best regards,
Yuri
