| |
| − | You may see this error when attempting to install the pytorch dependencies in a local anaconda environment. This error indicates that some of your installed python packages are not compatible with the pytorch prequisites. In particular, we see this error when conda has been updated to version 4.6 (which may sometimes happen when installing the tensorflow dependencies first).

| − |
| |
| − | To resolve this problem, create a new environment with a 4.5.x conda version and then install the pytorch dependencies in that environment.
