Transforming image from react.js into tensor issue

[Sergy Youbi]

Hi folks, i hope ya'll doing good ! 

I've trained a cnn model in python , then I saved it as a json model (model.json) to use it later in my Node.js  server ( i want to predict in server side ).  The image that I want to predict come from React.js (req.files) , but I'm having issue (error) transforming the image into tensor. How to do it propery ?  Please see attachement to look  code image. thanks !!!!

the code:

const image = req.files.image;

const tensor = tf.browser

.fromPixels(files)

.resizeNearestNeighbor([256, 256])

.mean(2)

.toFloat()

.div(tf.scalar(255.0))

.expandDims()

.expandDims(-1);

There is a general forum that is probably a better place to find help: https://discuss.tensorflow.org/

The error is a bad image shape, so I would look at the shape of the output of each step in the above chain.

I don't know this library, but what is the purpose of "mean(2)" ?
