+#### Missing MIopen.so.1
+
+This can happen when you upgrade Torch to a version that was built against a more recent version of ROCm than the one
+you are using.
+
+This can sometimes be fixed by upgrading ROCm, but make sure to check the supported architectures before you upgrade,
+since they often remove support for older GPUs.
+
+If you cannot upgrade ROCm, downgrade Torch to the correct version for the libraries available on your machine.
