Check your dll function api right, or use static plugin.
dumpbin /exports ./plugin_lib.dll

getCreators (previously known as getPluginCreators) has to be implemented in the plugin shared library if you want to use trtexec --dynamicPlugins.

yes, this is documented in https://docs.nvidia.com/deeplearning/tensorrt/developer-guide/index.html#generating-plugin-library, will close this, thanks all!

No, it did not say it is a must for trtexec.

No, it did not say it is a must for trtexec.

This is a must if you want your plugin work with the version compatibility feature. However, I reopen this created internal issue to track the document update for this.

solved by adding methods mentioned in 9.9.1. Generating Plugin Shared Libraries
