Still error eventhough i run it manually as below, please help

Then successfully update conda env as below

conda env update --file "C:\DeepLearning\cntk\Scripts\install\windows\conda-windows-cntk-py35-environment.yml" --name "C:\local\Anaconda3-4.3.1-Windows-x86_64\envs\cntk-py35"

That looks an intermittent issue. https://anaconda.org/main/pyqt/files does have https://anaconda.org/main/pyqt/5.6.0/download/win-64/pyqt-5.6.0-py35ha878b3d_6.tar.bz2 listed

Please reopen this issue if it happens again
