Still no luck. getting the same error when I uninstall and then reinstall using python -m pip install -U QuantLib and python -m pip install -U QuantLib-python Sent from Outlook<http://aka.ms/weboutlook> ________________________________ From: Luigi Ballabio <lui...@gm...> Sent: Tuesday, November 17, 2020 2:09 PM To: Teddy O <tm...@ho...> Cc: qua...@li... <qua...@li...> Subject: Re: [Quantlib-users] DLL Load Failed Ok, I see. The DLL you have, _QuantLib.cp37-win_amd64.pyd, is compiled for Python 3.7. You probably have multiple versions of Python installed, and the version of pip you used to install QuantLib was the one for 3.7. Instead of calling pip directly (which might give you the wrong version for the Python you want to use), you can try something like python -m pip install -U QuantLib which will use the pip corresponding to the python you're running.
