Unable to import loaded module.

[medcelerate]

I compiled the module successfuly but attempting to load it while in the same directory as the so fields yields the below error.

Traceback (most recent call last):
  File "input.py", line 3, in <module>
    import NDIlib as ndi
ModuleNotFoundError: No module named 'NDIlib'

@medcelerate What OS are you using? In windows, you needs to copy the following libraries to execute directory.

NDIlib.cp**-win_amd64.pyd
Processing.NDI.Lib.x64.dll

In macOS,

NDIlib.cpython-**m-darwin.so
libndi.4.dylib

[Hantoo]

Are these files generated upon build?

[medcelerate]

Let me try copying the Dylib to the folder. I need to see the exact file generated but it is and NDIlib*.so file

Interesting, I seem to be missing some files then. I'm building with NDI 4.5 SDK. Is this the right SDK version to be using? or was this made for NDI 3.x?

[pasanm2]

Did anyone find a solution?

[medcelerate]

Unfortunately I haven’t yet.

I didn't either. I had success with pyNDI

[pasanm2]

Thanks for the suggestion. Will give it a try!

Got examples to work with NDI SDK 4.5 (latest) installed on Ubuntu 20.4, just moved the built file NDIlib.cpython-38-x86_64-linux-gnu.so into the examples folder. Should be possible to install the lib to Python site-packages but I'm unsure how at the moment. Simpler solutions to access the lib is by setting up a custom folder wherein you put a symlink to the built lib file I mentioned, following the steps here: https://askubuntu.com/a/250935 (Linux OS only).

On Windows, I cannot find "Processing.NDI.Lib.x64.dll" after build process.

mkdir build cd build cmake .. cmake --build . --config Release

After this, files I see in Release directory are following 3, not including the "Processing..." file.

NDIlib.cp38-win_amd64.pyd NDIlib.exp NDIlib.lib

On windows the Processing.NDI.Lib.x64.dll is located at C:\Program Files\NDI\NDI 5 SDK\Bin\x64 after installing NDI 5 SDK from https://www.ndi.tv/sdk/ copy Processing.NDI.Lib.x64.dll to your example folder and you will be good to go!

[simulateduniverse]

I've exactly did what you say but nothings happens. Also my files don't have .dll extension but only .lib.

Does someone know a way to import NDI module correctly?

Sorry the dll is located at C:\Program Files\NDI\NDI 5 SDK\Bin\x64 ( I corrected the original reply above)

[buresu]

Sorry for late reply. ndi-python support pypi repository now. Please try to install it from pip.

pip install ndi-python

Solved this issue on Ubuntu 20 and NDI 5 SDK as follows:

You just need to set LD_LIBRARY_PATH to include the folder in which the shared libraries are present. For me, sourcing the lib.linux-x86_64-3.8 inside the build folder solved the error.

Eg: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/ndi-python/build/lib.linux-x86_64-3.8/NDIlib:$LD_LIBRARY_PATH

Hello,

I have difficulties running the examples on macos (Apple Silicon chip):

I followed these steps:

And here is the output (seems to work):

Then I copied the files that were created in the examples directory:

But this still doesn't work... Am I missing something?

Thank you,

Rayan

Edit: I should add that with pip it does not work either and I obtain the error below

@rayandaod Hi I have tried to support arm cross-compilation on mac with the latest build 4117651c8aeef18ee2cce7dfe90269841edbdb29. Please pull the latest changes and rebuild.

git pull
git clean -fdx
python setup.py build

and check the supported architectures.

file NDIlib.cpython-37m-darwin.so

If you get the following output, you have cross-compiled binary.

NDIlib.cpython-37m-darwin.so: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit dynamically linked shared library x86_64] [arm64]
NDIlib.cpython-37m-darwin.so (for architecture x86_64):	Mach-O 64-bit dynamically linked shared library x86_64
NDIlib.cpython-37m-darwin.so (for architecture arm64):	Mach-O 64-bit dynamically linked shared library arm64

Unfortunately I don't have an m1 mac so I can't confirm it works :( And pip binary is only supported for x86_64 now.

[buresu]

I uploaded cross-compiled binary to pypi. Please try to run pip install again.

pip install ndi-python --force

[rayandaod]

Hello @buresu!

Thank you for your answer.

I have done what you suggested and I indeed obtain the expected output:

NDIlib.cpython-37m-darwin.so: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit dynamically linked shared library x86_64] [arm64]
NDIlib.cpython-37m-darwin.so (for architecture x86_64):	Mach-O 64-bit dynamically linked shared library x86_64
NDIlib.cpython-37m-darwin.so (for architecture arm64):	Mach-O 64-bit dynamically linked shared library arm64

Unfortunately, I still can't run the example scripts (No module named 'NDIlib' error remains)... Am I adding the right files to the examples folder (cf screen capture previously sent)?

I also tried with pip again by removing the cache and running the command you sent, but the result is the same as before.

Thank you, Rayan

[rayandaod]

I have finally managed to make it work by running the scripts with /opt/homebrew/bin/python3 instead of usr/bin/python3 😅 I guess I wasn't using the right python installation. Thank you for your help!

[buresu]

@rayandaod Thank you for trying. I'm glad you were able to solve it!

[hendryman]

I am on a Macbook Pro M1, installed ndi-python sucessfully from PyPi and NDI SDK 5 from NDI's official installer. Still, upon running the Python example scripts, I get this error:

import NDIlib as ndi
ModuleNotFoundError: No module named 'NDIlib'

What am I doing wrong?

[altarbeast]

I am still unable to run any of the examples on Windows... same error, even after copying the suggested dll to the examples folder "Processing.NDI.Lib.x64.dll" still the same error:

``ModuleNotFoundError: No module named 'NDIlib.NDIlib'

Even trying with different version of Python but no luck... same error every time.

Any workaround?

Experiencing the same issues. I was able to compile it from source and I assume I have all files needed accessible in PATH

NDI SDK also installed properly.
