Hi,
Im facing with installation problem of : node-red-contrib-tf-model. So, i went throught steps like here : [https://www.npmjs.com/package/node-red-contrib-tf-model](https://www.npmjs.com/package/node-red-contrib-tf-model) (skipping the Note section, cause Im working on windows ). So, when running the node-red i have some warning: `

Your flow credentials file is encrypted using a system-generated key.
If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.
## You should set your own key using the 'credentialSecret' option in your settings file. Node-RED will then re-encrypt your credentials file using your chosen key the next time you deploy a change.

# ============================ Hi there �. Looks like you are running TensorFlow.js in Node.js. To speed things up dramatically, install our node backend, which binds to TensorFlow C++, by running npm i @tensorflow/tfjs-node, or npm i @tensorflow/tfjs-node-gpu if you have CUDA. Then call require('@tensorflow/tfjs-node'); (-gpu suffix for CUDA) at the start of your program. Visit [https://github.com/tensorflow/tfjs-node](https://github.com/tensorflow/tfjs-node) for more details.

Apart of that, Im not able to see the installed tf-model in the pallete. Do you have some prompts for me ?

Why did you skip the node part ? You need to install it correctly.
