This package is not working properly in Windows @soft-matter @aaristov . Even after your version 1.1.

I just made a quick test in Miniconda on Windows 10 with pims_nd2 1.1 and python -c "import pims_nd2" works without problems. Please provide us with more details about your system configuration. Which Windows version you use, which python distribution, etc.

+1 on this. Mine also does this in a anaconda environment when pims is half broken. I recommend removing and installing pims.

Hi, I am getting the following error. Please help me to solve it. I am super new to the Python.

File "", line 1, in

File "e:\Example1.py", line 65, in main

server = windll.LoadLibrary("C:/IMPL/IMPLserver.dll")

File "C:\Users\Andrew\AppData\Local\Programs\Python\Python39\lib\ctypes_init_.py", line 452, in LoadLibrary

return self._dlltype(name)

File "C:\Users\Andrew\AppData\Local\Programs\Python\Python39\lib\ctypes_init_.py", line 374, in init

self._handle = _dlopen(self._name, mode)

FileNotFoundError: Could not find module 'C:\IMPL\IMPLserver.dll' (or one of its dependencies). Try using the full path with constructor syntax.

I found the answer. There is a problem with python versions. If you use python >= 3.8 then you should do the following:

Before that:

server = windll.LoadLibrary("C:/IMPL/IMPLserver.dll")

you should write all paths of dll-dependencies by function os.add_dll_directory() like this:

os.add_dll_directory("Path to dll-dependencies for your dll library").

For example I have a library Library.dll which I downloading by windll.LoadLibrary(). And I have dependency "sublibrary.dll" that used in Library.dll and locate in "C://libs". So, I should call the following before windll.LoadLibrary():

import os
os.add_dll_directory(C://libs)

This is the answer!
