I'm trying to run the following code,
from pykinect import nui
from pykinect.nui import JointId
from pykinect.nui import SkeletonTrackingState
from pykinect.nui import TransformSmoothParameters
with nui.Runtime() as kinect:
kinect.skeleton_frame_ready+=skeleton_frame_ready
kinect.skeleton_engine.enable=True
while True:
frame= kinect.skeleton_engine.get_next_frame()
for skeleton in frame.SkeletonData:
def skeleton_fram_raedy(skeleton_frame):
for index,data in enumerate(skeleton):
if skeleton.eTrackingState==nui.SkeletonTrackingState.TRACKED:
head=data.SkeletonPositions[JointId.Head]
print head
but Kinect shuts down and gives the following error:
Traceback (most recent call last):

I'm new to PyKinect so any help is appreciated! Thanks!
Firstly, there are typos in your code. You're assigning a callback to skeleton_frame_ready function in kinect.skeleton_frame_ready+=skeleton_frame_ready, but have defined it as def skeleton_fram_raedy(skeleton_frame).
Secondly, I think your indentation is off, you have a function definition in a for loop in a while loop:
while True:
frame= kinect.skeleton_engine.get_next_frame()
for skeleton in frame.SkeletonData:
def skeleton_fram_raedy(skeleton_frame):
...
Try something like this:
from pykinect import nui
from pykinect.nui import JointId
from pykinect.nui import SkeletonTrackingState
from pykinect.nui import TransformSmoothParameters
def skeleton_frame_ready(skeleton_frame):
for skeleton in frame.SkeletonData:
if skeleton.eTrackingState==nui.SkeletonTrackingState.TRACKED:
for index,data in enumerate(skeleton):
head=data.SkeletonPositions[JointId.Head]
print head
with nui.Runtime() as kinect:
kinect.skeleton_frame_ready+=skeleton_frame_ready
kinect.skeleton_engine.enable=True
while True:
frame= kinect.skeleton_engine.get_next_frame()
Thirdly, the error indicates that invalid argument is passed to nui for the kinect camera angle. Not sure why that is. You could try setting the elevation angle to 0 right after initializing nui:
with nui.Runtime() as kinect:
kinect.camera.elevation_angle = 0
kinect.skeleton_frame_ready+=skeleton_frame_ready

Hey i am trying to locate an image but get this error on why i use the value as (any,any,250,250) but doesnt show the error when i use(any,any,350(more than 350),250(more than 250))

Because the region has to be bigger than your player.png image. Either crop your player.png image or increase the region size
I am making a bot that makes the chrome dinosaur jump every time it sees a cactus.
The RGB for the cactus is (83,83,83)
I made a specific coordinate for my code to look at, and check if the RGB of that pixel matches the cactus (jump_place)
However, when I run it, it works for about 2 seconds, and then gives me this error:

print("Jump!")
pyautogui.keyUp('space')
restart()
while keyboard.is_pressed('p') == False:

Is there anything I am doing wrong?

I'm a beginner with myhdl.
I try to translate the following Verilog code to MyHDL:
module ModuleA(data_in, data_out, clk);
input data_in;
output reg data_out;
input clk;
always #(posedge clk) begin
data_out <= data_in;
end
endmodule
module ModuleB(data_in, data_out, clk);
input [1:0] data_in;
output [1:0] data_out;
input clk;
ModuleA instance1(data_in[0], data_out[0], clk);
ModuleA instance2(data_in[1], data_out[1], clk);
endmodule
Currently, I have this code:
import myhdl
#myhdl.block
def ModuleA(data_in, data_out, clk):
#myhdl.always(clk.posedge)
def logic():
data_out.next = data_in
return myhdl.instances()
#myhdl.block
def ModuleB(data_in, data_out, clk):
instance1 = ModuleA(data_in(0), data_out(0), clk)
instance2 = ModuleA(data_in(1), data_out(1), clk)
return myhdl.instances()
# Create signals
data_in = myhdl.Signal(myhdl.intbv()[2:])
data_out = myhdl.Signal(myhdl.intbv()[2:])
clk = myhdl.Signal(bool())
# Instantiate the DUT
dut = ModuleB(data_in, data_out, clk)
# Convert tfe DUT to Verilog
dut.convert()
But it doesn't works because signal slicing produce a read-only shadow signal (cf MEP-105).
So, what is it the good way in MyHDL to have a writable slice of a signal?
Edit:
This is the error I get
$ python demo.py
Traceback (most recent call last):

#myhdl.always_comb
def assign():

A quick (probably non-fulfilling) comment, is that the intbv is treated as a single entity that can't have multiple drives. Two references that might help shed some light:

I am wondering why I can get this error:

from pyglet import image
from pyglet.gl import *
from pyglet.graphics import TextureGroup
from pyglet.window import key, mouse, Window
from PIL import Image
I'm using PIL for making the PNG:
print "Creating ", TEXTURE_PATH
images = map(Image.open, texture_path)
widths, heights = zip(*(i.size for i in images))
total_width = sum(widths)
max_height = max(heights)
new_im = Image.new('RGB', (total_width, max_height))
x_offset = 0
for im in images:
new_im.paste(im, (x_offset,0))
x_offset += im.size[0]
new_im.convert('RGB')
new_im.save(TEXTURE_PATH, "PNG")
And the 'texture_path`(lowercase) is here:
texture_path = ['res/textures/grass_top.png'] * 99
The full error message is:

I found the problem, but didn't know how to fix it, the problem are in the PNG making.
When I replace the textures.png with another picture, it's working
but when I make one with PIL, it doesn't work.
Solved: the problem is in my .PNG Editor, i just make the image manually and it works!
im using Graphics Gale Free edition to edit and it will work.
i think the problem is in the PIL itself. Or The pyglet doesnt load PIL config PNG
P.s it may be because color configuration

As described in the python-weka-wrapper API you have to import and start the Java Virtual Machine:
import weka.core.jvm as jvm
jvm.start()
It should solve your problem.
