Hi kzhangkzhang!
I don't think that it is supported on Windows platform yet.
https://www.npmjs.com/package/@tensorflow/tfjs-node
I do not know if this is something to look into but, I was looking at this other tutorial and I was able to run the app via npm without a problem:
Perhaps he is using a different npm package: https://www.npmjs.com/package/@tensorflow/tfjs
https://github.com/llSourcell/Financial_Forecasting_with_TensorflowJS

Thanks,

hi, i wanted to ask regarding this model,
Des this model works on data that consist of unclassified data?
for example, i tried to create the neural network from on my PCA(Principal Component Analysis) data. however, the result of my PCA data only consists of numbers that based on how many PC i used after i ranked it by based their variance. how i add it into this type of model?
thank you
Hello. Thanks a lot for this example, it helped me a lot.
I'm still new to tfjs and I'm still struggling with 1 thing and was hoping if you could help.
in file iris-tensorflow-js.js line 16 , what if, for example, sepal_length is of type String and not an integer?
thanks in advance

I am using Windows 10 with node v8.9.4. I duplicated package.json like yours, then issue 'npm install' and I got bunch of errors:

Do you know why I am getting such error?
Thanks!
