I wanted to install Detectron 1, so I tried to install Caffe2 before that. I followed the official instructions.
After I typed conda install -c caffe2 caffe2-cuda8.0-cudnn7, I got the following:

Solving environment: failed
UnsatisfiableError: The following specifications were found to be in conflict:

blaze
caffe2-cuda8.0-cudnn7
Use "conda info " to see the dependencies for each package.


Any idea what should I do please? Thank you in advance.
