[英]brain.js problem with importing LSTM network from json
I've made a brain.js LSTM network, predicting addition.我制作了一个brain.js LSTM 网络,预测加法。 Then I saved it to a .json file using
net.toJSON()
However, it doesn't seem to work.然后我使用
net.toJSON()
将它保存到一个net.toJSON()
文件中,但是,它似乎不起作用。 The traindata.json
was successfully created, no errors. traindata.json
已成功创建,没有错误。 However, I get an error:但是,我收到一个错误:
/home/runner/AngryBlaringTelevision/node_modules/brain.js/dist/brain.js:18102
var matrix = new Matrix(json.rows, json.columns);
^
TypeError: Cannot read property 'rows' of undefined
at Function.fromJSON (/home/runner/AngryBlaringTelevision/node_modules/brain.js/dist/brain.js:18102:36)

at /home/runner/AngryBlaringTelevision/index.js:9:7
at FSReqCallback.readFileAfterClose [as oncomplete] (internal/fs/read_file_context.js:63:3)
My code:我的代码:
const brain = require('brain.js');
const fs = require('fs');
const LSTM = brain.recurrent.LSTM;
const net = new LSTM();
fs.readFile('traindata.json', function(err, data) {
if (err) throw err;
net.fromJSON(data);
console.log("file loaded");
});
Also, here's the link to my traindata.json
file on pastebin: https://pastebin.com/tBZyxq1R I don't have an idea how to solve this error.另外,这是我在 pastebin 上的
traindata.json
文件的链接: https : traindata.json
我不知道如何解决这个错误。 It seems like it's an error with brain.js.这似乎是brain.js 的错误。
I have also tried net.run()
after importing the file, but it also didn't work.导入文件后我也尝试过
net.run()
,但它也不起作用。
I think what might be going on is that what you're passing into BrainJS is not actually JSON.我认为可能发生的情况是您传递给 BrainJS 的实际上并不是 JSON。
In your code, you have this:在你的代码中,你有这个:
fs.readFile('traindata.json', function(err, data) {
if (err) throw err;
net.fromJSON(data);
console.log("file loaded");
});
When I tried running your code, I saw the same error you saw.当我尝试运行您的代码时,我看到了与您看到的相同的错误。 Using
JSON.parse()
seemed to fix the issue.使用
JSON.parse()
似乎解决了这个问题。
In other words, when I changed net.fromJSON(data);
换句话说,当我改变
net.fromJSON(data);
to net.fromJSON(JSON.parse(data));
到
net.fromJSON(JSON.parse(data));
, the error disappeared. ,错误消失了。
