[Caffe2] install failed, conflict with blaze

I wanted to install Detectron, 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.

I updated my conda to the latest. Then I tried to build from source and it worked.
