Unable to install pyk4a using pip3

[vnt1537]

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]

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]

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]

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]

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]

Thank you very much! This worked!

[kramakr4]

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

from pyk4a import PyK4A
Traceback (most recent call last):
File "", line 1, in

Here is the link to the pyk4a module: https://github.com/etiennedub/pyk4a

[zapaishchykova]

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]

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

[zapaishchykova]

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

[dmorris0]

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

[zapaishchykova]

@dmorris0

[dmorris0]

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

>>> from pyk4a import PyK4A
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\morri\Source\envs\cv\lib\site-packages\pyk4a\__init__.py", line 1, in <module>
    import k4a_module
ImportError: DLL load failed while importing k4a_module: The specified module could not be found.

[zapaishchykova]

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

[dmorris0]

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

[zapaishchykova]

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]

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]

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

[dmorris0]

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

[shagren]

@dmorris0 , please check this: #117 (comment)

[dmorris0]

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

[juancarlosmiranda]

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

• pip install pyk4a --no-use-pep517 --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"
• Path checked in: C:\Program Files\Azure Kinect SDK v1.4.1\sdk\windows-desktop\amd64\release\bin
• A helper functions in a file

This problem is fixed in the dev.
The next version will solve these windows install issues.

[juancarlosmiranda]

Thanks @lpasselin !!! my respects and congratulations for the great work!!

Thank @shagren!

[YoniChechik]

In windows: adding C:\Program Files\Azure Kinect SDK v1.4.1\sdk\windows-desktop\amd64\release\bin to the PATH env var (via edit envinronment variables) solved it for me
