Hey. I am trying to run a object detection flow in the node red on mu raspberry pi 4, but my tfjs object detection node gives out his error message:

msg : error

"TypeError: Cannot read property 'whereImpl' of undefined"

Any suggestions on how to fix this issue? Thank you

Hi @TinkyLv

which node exactly are you trying to use? There are a few that use TFJS.

I've the same error using the IBM Tensorflow Object Detection package from  
[https://github.com/IBM/node-red-tensorflowjs](https://github.com/IBM/node-red-tensorflowjs)

After reinstallation, checking all dependencies, etc. i've no more idea how to fix it.  
The node does not connect to the model - doesnt matter if i give it the local path or leave it empty (where it should load the model from public sources according to the developer)  
I run the package on a RPI 4 (updated and upgraded).
