getPluginCreator could not find plugin BatchedNMS_TRT version 1

I am having the exact same errors as the original poster. I tried both versions 19.12 and 20.1 through pip3. I also flashed down to JetPack 4.2 with version 19.11, but I get a similar error about not finding the BatchedNMS_TRT plugin…
