无法将@ tensorflow / tfjs-node导入我的程序。 我试图按如下方式导入它:

const tf = require('@tensorflow/tfjs-node')

并收到如下错误:

internal/modules/cjs/loader.js:638
    throw err;
    ^

Error: Cannot find module '/home/nama/working/Canvas-WEB/node_modules/@tensorflow/tfjs-node/lib/napi-v4/tfjs_binding.node'

    at tryModuleLoad (internal/modules/cjs/loader.js:593:12)
    at Function.Module._load (internal/modules/cjs/loader.js:585:3)

但是当我尝试将@ tensorflow / tfjs导入为

const tf = require('@tensorflow/tfjs')

没有遇到错误。

我使用npm安装了@ tensorflow / tfjs-node

sudo npm install @tensorflow/tfjs-node

然后得到一个输出(如下):

@tensorflow/tfjs-node@1.2.7 install /home/nama/working/Canvas-WEB/node_modules/@tensorflow/tfjs-node


node scripts/install.js

这里有两个问题。

以root身份安装软件包

您要以root身份安装依赖项,但默认情况下npm不会以root身份运行。传递the following arguments以启用root特权:

text = input()
parts = text.rstrip().split(".") # no need for map, because split returns a list of strings.
print(".".join(reversed(parts)))

您还应该重新考虑使用其他(不是root)来运行脚本。

Tensorflow.js要求

sudo npm install @tensorflow/tfjs-node --unsafe-perm=true --allow-root 的require将无法按您的方式工作,软件包tensorflow/tfjs-node将不会导出任何内容,仅使用本机C ++绑定才需要。

这是应该如何做(引用tutorial):

@tensorflow/tfjs-node

我遇到了同样的问题,并通过在node_modules/@tensorflow/tfjs-node处运行以下命令来解决了该问题

$ cd node_modules/@tensorflow/tfjs-node/
$ npm install
> @tensorflow/tfjs-node@1.2.6 install /Users/tomoima525/workspace/javascript/tensorflow/baseball/node_modules/@tensorflow/tfjs-node
> node scripts/install.js

另外,您可能想尝试使用tfjs-node的1.2.6,我可以使用。
