Hello
Whenever I try to install
node-red-contrib-tf-model
I get this error
```auto

Did you install the prerequisites as defined on the [node's page](https://flows.nodered.org/node/node-red-contrib-tf-model)?

What platform are you running node-red on?
What version of NR and node.js (you can get this from the start up log)
(Sorry I took so long to get back to - family matters)

No worries..
I run it on Mac and
[info] Node-RED version: v2.0.5
[info] Node.js version: v16.11.1

On my mac - running node.js 14.16.0 - I opened a terminal window and ran
```auto
cd .node-red
npm install @tensorflow/tfjs-node
npm install node-red-contrib-tf-model
```
and it seemed to import fine. So it may be a node.js version issue.
What version of macOS are you running and what type of Mac are you using?
Note - I do get this when NR starts up:
```auto

I have macOS Big Sur 11.6 on Macbook air 2017.
I updated the version on Node.js, but still getting the same error when I run
```auto
npm install node-red-contrib-tf-model

Don't do that. It may break your system.

Did you update or downgrade? So what version of node.js are you now running? (just enter `node -v` in a terminal session)
I'm also running macOS v11.6 on a Mac mini (M1) running node v14.16.0
Here is my install log:

I have node.js version v16.11.1
should I try this command
`npm install --legacy-peer-deps`
??

You can try anything you like, but it won't change the error you showed earlier, if indeed the error you are now getting is exactly the same.
To check that node\_modules is not messed up then rename the .node-red/node\_modules folder to something else, and in the .node-red folder run
`npm install`
(which may take some time) and, assuming that runs without error, then try installing the node again. If it fails then please post the full log including the command you entered.

Can you downgrade node.js to v14.16.0?

I tried it and it worked. I will be using a new machine soon. So the temporary solution fine for me now.
Thanks
