Saving model on node to filesystem

[Tiago Vasconcelos]

I'm getting an error saving my model: Cannot find any save handlers for URL 'file://model/'

Can someone give a hand?!

[Nikhil Thorat]

Can you give us more information? Can you post your code here? Running in browser or Node? TensorFlow.js version? etc.

sorry... 

running on windows, no browser just node, using latest tfjs 

load().then(async () => {

 await train()

 await test()

 await model.save('file://model/')

}).catch(console.error)

load, just loads the data, run train, then predictions, after that o try to save the model to the filesystem... is it a windows thing?

Tiago, 

This could be a tfjs bug on Windows, as we currently don't have CI testing for tfjs-node on Windows. Can you try one thing? Instead of the URL 'file://model/', can you add './' in front of 'model', i.e., 'file://./model/'? This way you can use a path relative to the current working directory. Let us know what happens with that URL. Thanks.

Best,

Shanqing

Same error, i guess i've tried it before. 

Tried, full path: c:/Users....... also, no go!! it may be a windows thing. i may get it to run from the browser then, cause it works there, i tried the download demo on the website. just need a few lines worked around...

[Shanqing Cai]

I will file an issue on GitHub to track this tfjs-node + Windows bug (after GitHub comes back online, that is!)

[Nick Kreeger]

Hi Tiago - 

We currently don't have a windows build for tfjs-node. This might be part of the problem. Can you provide the full source code (github link?), and any other output to the Github issue?

Thanks,
Nick

Tiago, 

Just to cover the ground: you said you were using the latest version of tfjs. How about the version of tfjs-node? It has a separate version from tfjs proper.

To use tensorflow.js in Node.js, you need to import tfjs-node. Otherwise, the native filesystem handler won't be available, which is probably the reason for the issue you are having. In addition, without importing Node.js, you will end up using the default JavaScript CPU math backend of tensorflow.js, which is way slower than the parallelized CPU or GPU backends that come with tfjs-node.

This is why i haven't installed tfjs-node:

npm ERR! code ELIFECYCLE

npm ERR! errno 1

npm ERR! @tensorflow/tfjs...@0.1.9 install: `node-gyp rebuild`

npm ERR! Exit status 1

npm ERR!

npm ERR! Failed at the @tensorflow/tfjs...@0.1.9 install script.

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

I get the same results. Tfjs-node doesn’t support Windows atm.
Go for a VM or use the Docker image someone posted a few posts back. It works fine!

[Iconoclasta Vesgo]

never used docker before... guess i'll give it a try
