First of all thank you for this repo. I am currently working on Nvidia Xavier and I receive the following error:

The error I receive is :

Hi, you probably forgot to add the k4a lib to the path. Check the readme for specific windows instructions. Can you show the command you used to install with pip?

vnt1537 commented 4 years ago

Thank you for the answer. Can you please tell me to which path do we need to add this k4alib? I added it to the folder where my build for k4aviewer is. I tried using sudo pip install pyk4a sudo pip3 install pyk4a And even sudo -H pip3 install pyk4a

lpasselin commented 4 years ago

pip3 usually refers to pip on recent systems. python 2 is not supported for this library.

Please read the readme. You need to specify the path to the pip command.

I will close as this is a problem with your management of your windows environment. I will continue to answer your questions in this thread.

vnt1537 commented 4 years ago

The issue is solved thank you.

Hi! I am facing a similar issue with pyk4a installation. Here is what I use:

I have also tried using this path: C:\Program Files\Azure Kinect SDK v1.4.1\sdk\windows-desktop\amd64\release\bin>

And also this command: pip install pyk4a --global-option=build_ext --global-option="-IC:\Program Files\Azure Kinect SDK v1.2.0\sdk\include" --global-option="-LC:\Program Files\Azure Kinect SDK v1.2.0\sdk\windows-desktop\amd64\release\lib"

Any combination of the above two paths and commands still gives similar error. Could you please help me with this? I am sorry if my question is too naive or dumb. I am new to coding and kinect environments.

lpasselin commented 4 years ago

fatal error C1083: Cannot open include file: 'k4a/k4a.h': No such file or directory is the error. You need to specify the path to k4a.h file by telling the compiler where they are. Usually compilers have a -I option to specify directories to include.

pip install pyk4a this will not work unless the includes (-I) and libraries (-L) are somehow given to the compiler. Which is why we need to specify their paths by adding options with --global-option.

For the second command you used, I guess you didn't notice you were including directories of a k4a SDK v1.2.0 while you seem to have v1.4.1 installed.

Try this instead: pip install pyk4a --global-option=build_ext --global-option="-IC:\Program Files\Azure Kinect SDK v1.4.1\sdk\include" --global-option="-LC:\Program Files\Azure Kinect SDK v1.4.1\sdk\windows-desktop\amd64\release\lib"

You should make sure this path exists in your system. Otherwise modify it to fit your k4a SDK install.

Hopefully this helps solve your problem. Sorry I am not a windows user and do not know any simple alternatives to this.

kramakr4 commented 4 years ago

Thank you very much! This worked!

kramakr4 commented 4 years ago

When I run the following command, I get an error:

from pyk4a import PyK4A Traceback (most recent call last): File "", line 1, in File "C:\Users\krr\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\pyk4a__init__.py", line 2, in from .pyk4a import * File "C:\Users\krr\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\pyk4a\pyk4a.py", line 2, in import k4a_module ImportError: DLL load failed while importing k4a_module: The specified module could not be found.

zapaishchykova commented 3 years ago

Hi @kramakr4! did you resolve this issue? I have all of the paths in the env of windows, and after the install was successful i also get

import k4a_module
ImportError: DLL load failed while importing k4a_module: The specified module could not be found.

Do you have any suggestions?

lpasselin commented 3 years ago

@zapaishchykova sorry I never saw this. Did you manage to make it work?

zapaishchykova commented 3 years ago

@lpasselin oh yes, a bit of manipulation with paths and it worked!

dmorris0 commented 3 years ago

@zapaishchykova What was the trick? I'm getting the same problem, and can't seem to find the right path to add.

zapaishchykova commented 3 years ago

@dmorris0

dmorris0 commented 3 years ago

Thanks -- but unfortunately adding that line to my path and restarting my terminal doesn't work for me. Still get the error:

zapaishchykova commented 3 years ago

@dmorris0 can you show me the contents of your \release\bin?

dmorris0 commented 3 years ago

Here is: C:\Program Files\Azure Kinect SDK v1.4.1\sdk\windows-desktop\amd64\release\bin

zapaishchykova commented 3 years ago

Do you specify in python path of the module?

import sys
sys.path.insert(1, '../pyKinectAzure/')
import numpy as np
from pyKinectAzure import pyKinectAzure,_k4a, postProcessing
import cv2
import time
import os

paths = []

# Path to the module
modulePath = r'C:\Program Files\Azure Kinect SDK v1.4.1\sdk\windows-desktop\amd64\release\bin'

if __name__ == "__main__":
    # Initialize the library with the path containing the module
    pyK4A = pyKinectAzure(modulePath)

    # Open device
    num_connected_devices = pyK4A.device_get_installed_count()
    print("[LOG]: Number of connected devices ",num_connected_devices)

dmorris0 commented 3 years ago

Ah interesting. I am trying to find out where your pyKinectAzure folder came from. That's not in the pyk4a repo as far as I can tell nor in the Azure Kinect SDK.

zapaishchykova commented 3 years ago

It should be this one https://github.com/ibaiGorordo/pyKinectAzure

dmorris0 commented 3 years ago

I see -- that looks like a very nice repo. Perhaps if I get that one working it will solve my module import problem? But I also discovered that Open3D can read directly from the Kinect, and I got that up and running very easily. I might just go with Open3D unless this repo has advantages. Thanks for your help @zapaishchykova

@dmorris0 , please check this: https://github.com/etiennedub/pyk4a/issues/117#issuecomment-816801446

dmorris0 commented 3 years ago

@shagren that looks exactly like what I need, but I run it and I get the same module error.

juancarlosmiranda commented 3 years ago

I had the same problem, but I solved applying #117 The solution given by @shagren was very useful. The steps applied were:
