Fix typo in gradient.js require

[superlaza]

On L2:C21 of src/inference/dream/gradient.js

var ad = require('..../ad');

is missing a forward slash.

Fix on dev branch, broken on npm release

Hi, thanks for mentioning this.

gradient.js is automatically generated from gradient.ad.js when the package is installed, and it's possible the ad import is getting messed up as part of that.

I've just installed the latest npm release locally, after which gradient.js was correct for me. Would you be able to uninstall/reinstall the webppl package and check whether the require in gradient.js is still wrong? If so, perhaps this is a problem specific to a particular node version or OS etc.

Thanks!

I just installed webppl through npm and it threw an error because of the var ad definition on line 2 in gradients.js.

> webppl test.wppl
module.js:529
    throw err;
    ^
 
Error: Cannot find module '..../ad'
    at Function.Module._resolveFilename (module.js:527:15)

    at Object.<anonymous> (C:\Users\user_name\AppData\Roaming\npm\node_modules\webppl\src\inference\dream\gradients.js:2:10)

The ad variable was defined twice, though, so I just commented out the first one and it now works.

use strict';
//var ad = require('..../ad'); //caused error
var assert = require('assert');
var _ = require('lodash');
var guide = require('../../guide');
var ad = require('../../ad');
module.exports = function (env) }

@spw1016 Thanks for reporting this! Looks like there might be a problem in Windows, I'll look into it.
