Question

I am trying to run "parallel" package on my 64 bit system.

Import parallel

But I am getting this Error. I think this is some DLL problem, but don't know which DLL I need and where to keep them.

My_Work\Signal_Generator_GUI\with_parallel.py", line 1, in <module>
    import parallel

  File "C:\Python27\lib\site-packages\parallel\__init__.py", line 13, in <module>
    from parallel.parallelwin32 import Parallel  # noqa

  File "C:\Python27\lib\site-packages\parallel\parallelwin32.py", line 60, in <module>
    _pyparallel = ctypes.windll.simpleio

  File "C:\Python27\lib\ctypes\__init__.py", line 435, in __getattr__
    dll = self._dlltype(name)

  File "C:\Python27\lib\ctypes\__init__.py", line 365, in __init__
    self._handle = _dlopen(self._name, mode)

WindowsError: [Error 193] %1 is not a valid Win32 application

Answer 1

You need to install simpleio.dll . Here is a giveio installer . Also, please take a look at this thread for same problem and examples as well. Finally, here is a github page discussing the same issue.
