import QCustomPlot2 ImportError: DLL load failed: The specified procedure could not be found

I am trying to get QCustomPlot2 working on Ppython 3.7 Anaconda installation Windows 10 x64

I tried installing via pip and easy_install from building qcustomplot2 via qt cmd and moved the .pyd file into several locations. I updated pyqt from conda which then broke the install. However even when qcustomplot2 was installed, and not giving the dll error I was getting the stack buffer overflow error when calling it from the example.

I am using the PyCharm IDE

Solution

  • Well, not really an answer but a workaround:

    I use PyQt5 instead of PySide2 and you have to import it prior to QCustomPlot2

    Doesn't work:

    >>> import QCustomPlot2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: DLL load failed while importing QCustomPlot2

    Works:

    >>> import PyQt5
>>> import QCustomPlot2
