Tfjs: Can't build tfjs-node on Windows 10; module_name not defined in binding.gyp.

[joemullenix-ks]

I'm unable to run tfjs-node. It reports a missing bindings file. I see the file in my project, but I haven't found a way to include it (via import or require).

I'm not certain, but it looks like "module_name" is referenced without being defined in binding.gyp

Hope this helps.

Please check related issue here ! Thank you

[joemullenix-ks]

I looked through the related issue, but was not able to fix the problem, unfortunately. I still see the same 'module_name undefined' error when I run node-gyp.

This is what I tried after reading the related issue:
TRIED npm rebuild @tensorflow/tfjs-node build-addon-from-source
RESULT no change

TRIED npm install npm@latest -g // note that I already had 6.14.8, but ran this anyway
RESULT no change

[rthadur]

can you please share your package.json ?

[joemullenix-ks]

Sure, it's below. It's very simple. I have rebuilt it many (many) times. I keep deleting node_modules and reinstalling, and trying different folders, and global vs local packages.

For the record, I have been using basic @tensorflow/tfjs without any problems, as a node program. Now I have a bug with model save/load, so I'm trying to move to tfjs-node (...and of course I want the performance boost from C++ :) )

"name": "PROJECT",
"version": "1.0.0",

same with me it's seems some of variables in binding.gyp are not defined?

[pyu10055]

@joemullenix-ks can you use the latest tfjs-node 2.7.0? I have uploaded the pre-compiled windows addons for 2.7.0, please let me know if that solve the problem for you.

[joemullenix-ks]

It looks like the problem still exists. I cleared my project, and reinstalled tfjs-node. My dependency is now 2.7.0.

When I run in VS Code, I still see the same error ('tfjs_binding.node not found'). Also, when I run node-gyp configure, I see the same undefined variable error.

Thanks for trying! Please let me know if I can do anything to help track this down.

[pyu10055]

@joemullenix-ks Looks like your issue is related to this bug https://github.com/tensorflow/tfjs/issues/4257, basically the dll file is not copied properly, when the node version is > 14.x

[joemullenix-ks]

Looks good! I manually copied the dll as mentioned in #4257, and tfjs-node now imports and runs correctly. Thanks!!
