Having trouble importing pylsl

[devaka40]

Hi everyone, I having trouble importing pylsl. Everytime I try to import it I get:

Traceback (most recent call last): File "C:/Users/computer/PycharmProjects/pythonProject1/MuseRead.py", line 33, in import pylsl File "C:\Users\computer\PycharmProjects\pythonProject1\venv\lib\site-packages\pylsl_init_.py", line 2, in from .pylsl import IRREGULAR_RATE, DEDUCED_TIMESTAMP, FOREVER, cf_float32,
File "C:\Users\computer\PycharmProjects\pythonProject1\venv\lib\site-packages\pylsl\pylsl.py", line 1217, in lib = CDLL(libpath) File "C:\Users\computer\AppData\Local\Programs\Python\Python37\lib\ctypes_init_.py", line 364, in init self._handle = _dlopen(self._name, mode) OSError: [WinError 193] %1 is not a valid Win32 application

I'm tried looking at the installation guide for pylsl and the only thing I can see is to use pip install pylsl which is what I used.

Thanks in advance to everyone that helps.

Same goes here:

Traceback (most recent call last): File "", line 1, in File "C:\Users\user1\anaconda3\lib\site-packages\pylsl_init_.py", line 2, in from .pylsl import IRREGULAR_RATE, DEDUCED_TIMESTAMP, FOREVER, cf_float32,

@bboyalu I got my problem solved, I had a rogue DLL in my system. Add a print(libpath) immediately before the lib = CDLL(libpath) line and try to import pylsl again? The location should match with the python library location where pylsl is present.

@Rakesh420 Ah, yes, thank you so much! For some reason it was pointing to the Muse SDK installation folder, C:\Program Files (x86)\Muse\lsl.dll. I uninstalled the Muse SDK and now I can import pylsl without any issue.

I think this is the piece of code that does that, but Muse SDK's lsl.dll is not working in this situation. path = util.find_library('lsl' + bitness + debugsuffix) or \ util.find_library('liblsl' + bitness + debugsuffix)

@bboylalu I had the same issue with the Muse SDK. I deleted the lsl.dll in the Muse folder. And when the printed the libpath, it showed in the proper directory. Now pylsl is working in my computer.
