Break down when clcking the map
Hi,
I want to edit gmapping map and just cloned this project and run
python MapEditor.py map.pgm
.
So, the UI came out, but it show the error below when I clicked the map.
Traceback (most recent call last): File "MapEditor.py", line 197, in mapClick self.im.putpixel((x,y), val) File "/usr/lib/python2.7/dist-packages/PIL/Image.py", line 1507, in putpixel return self.im.putpixel(xy, value) TypeError: integer argument expected, got float
When I switch to python3 and run, it shows that
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb.
I'm not familiar with QT, and can't get a solution from the web. So, how would I fix it?
@TrayfourYu TypeError: integer argument expected, got float
can be fixed by adding int()
to 3 lines of code in MapEditor.py
.
L48 self.min_multiplier = int(math.ceil(view_width / self.map_width_cells)) L69 x = int(math.floor(x / self.pixels_per_cell)) L70 y = int(math.floor(y / self.pixels_per_cell))
The return value of math.ceil
and math.floor
was float
in 2.7 while it's int
in some later versions.
