There are several posts about how to encode categorical data to Sklearn Decision trees, but from Sklearn documentation, we got these 

&gt; Some advantages of decision trees are:
&gt; 
&gt; (...)
&gt;
&gt; Able to handle both numerical and categorical data. Other techniques are usually specialized in analyzing datasets that have only one type of variable. See the algorithms for more information.

But running the following script
&lt;!-- language: lang-python --&gt;
    
    import pandas as pd 
    from sklearn.tree import DecisionTreeClassifier
    
    data = pd.DataFrame()
    data[&#39;A&#39;] = [&#39;a&#39;,&#39;a&#39;,&#39;b&#39;,&#39;a&#39;]
    data[&#39;B&#39;] = [&#39;b&#39;,&#39;b&#39;,&#39;a&#39;,&#39;b&#39;]
    data[&#39;C&#39;] = [0, 0, 1, 0]
    data[&#39;Class&#39;] = [&#39;n&#39;,&#39;n&#39;,&#39;y&#39;,&#39;n&#39;]

    tree = DecisionTreeClassifier()
    tree.fit(data[[&#39;A&#39;,&#39;B&#39;,&#39;C&#39;]], data[&#39;Class&#39;])

outputs the following error:

    Traceback (most recent call last):
      File &quot;&lt;stdin&gt;&quot;, line 1, in &lt;module&gt;
      File &quot;/usr/local/lib/python2.7/site-packages/sklearn/tree/tree.py&quot;, line 154, in fit
        X = check_array(X, dtype=DTYPE, accept_sparse=&quot;csc&quot;)
      File &quot;/usr/local/lib/python2.7/site-packages/sklearn/utils/validation.py&quot;, line 377, in check_array
        array = np.array(array, dtype=dtype, order=order, copy=copy)
    ValueError: could not convert string to float: b

I know that in R it is possible to pass categorical data, with Sklearn, is it possible?

If I accidentally press any key and the cursor goes somewhere else, how do I return to previous location? What is shortcut key for that?

Any extension that may help.

I&#39;m in the process of making the move from Webstorm to Visual Studio Code.  The Performance in Webstorm is abysmal.

Visual studio code isn&#39;t being very helpful about finding the dependencies I need and importing them.  I&#39;ve been doing it manually so far, but to be honest I&#39;d rather wait 15 seconds for webstorm to find and add my import that have to dig around manually for it.

I&#39;m using the angular2 seed from @minko-gechev  https://github.com/mgechev/angular2-seed

I have a tsconfig.json in my baseDir that looks like this:

        {
      &quot;compilerOptions&quot;: {
        &quot;target&quot;: &quot;es5&quot;,
        &quot;module&quot;: &quot;commonjs&quot;,
        &quot;declaration&quot;: false,
        &quot;removeComments&quot;: true,
        &quot;noLib&quot;: false,
        &quot;emitDecoratorMetadata&quot;: true,
        &quot;experimentalDecorators&quot;: true,
        &quot;sourceMap&quot;: true,
        &quot;pretty&quot;: true,
        &quot;allowUnreachableCode&quot;: false,
        &quot;allowUnusedLabels&quot;: false,
        &quot;noImplicitAny&quot;: true,
        &quot;noImplicitReturns&quot;: true,
        &quot;noImplicitUseStrict&quot;: false,
        &quot;noFallthroughCasesInSwitch&quot;: true
      },
      &quot;exclude&quot;: [
        &quot;node_modules&quot;,
        &quot;dist&quot;,
        &quot;typings/index.d.ts&quot;,
        &quot;typings/modules&quot;,
        &quot;src&quot;
      ],
      &quot;compileOnSave&quot;: false
    }


and I have another one in my src/client dir that looks like this:

    {
      &quot;compilerOptions&quot;: {
        &quot;target&quot;: &quot;es5&quot;,
        &quot;module&quot;: &quot;commonjs&quot;,
        &quot;moduleResolution&quot;: &quot;node&quot;,
        &quot;sourceMap&quot;: true,
        &quot;emitDecoratorMetadata&quot;: true,
        &quot;experimentalDecorators&quot;: true,
        &quot;removeComments&quot;: false,
        &quot;noImplicitAny&quot;: false,
        &quot;allowSyntheticDefaultImports&quot;: true
      }
    }

I don&#39;t know why there are two.  The angualr seed project uses typescript gulp build tasks so I guess the compilation is different.


What can I do get vscode to be more helpful??

Visual Studio Code Automatic Imports

I tried to merge my branch with another branch and there was a merge conflict. In Visual Studio Code (version 1.2.1) I resolved all of the issues, however when I try to commit it keeps giving me this message:

&gt; You should first resolve the un-merged changes before committing your changes.

I&#39;ve tried googling it but I can&#39;t find out why it won&#39;t let me commit my changes, all of the conflicts have disappeared.

I receive the warning...

&gt; Experimental support for decorators is a feature that is subject to change in a future release. Set the &#39;experimentalDecorators&#39; option `to remove this warning.

... even though my compilerOptions in tsconfig.json have the following settings:


    &quot;emitDecoratorMetadata&quot;: true,
    &quot;experimentalDecorators&quot;: true,


What is weird is that some random classes that use decorators do not show that warning but the rest in the same project do.

What could cause such behavior in the TypeScript compiler?

Experimental decorators warning in TypeScript compilation

I am writing javascript and am currently doing simple exercises/programs.  At times, I wish to run my file for testing purposes.  I am aware I could create an `HTML` file and do this within the console.  In Sublime, there exists a way to &quot;build&quot; the current file and immediately see the results (say, whatever is sent to console.log). 

With VS Code, it seems that for every file I want to &quot;build&quot;/debug in this manner, I must manually change the `launch.json` file to reflect the name of the current program.  

I have been researching a way around this, and I learned that there are variables like `${file}` , but when I use that in the `launch.json` &quot;program&quot; attribute, for example: 

    &quot;program&quot;: &quot;${workspaceRoot}/${file}&quot;

with or without the `workspaceRoot` part, I get the following error: 

    Attribute &quot;program&quot; does not exist&quot; (file name here). 

Am I missing a simple way to accomplish this, or must I keep editing `launch.json` every time I want to run the file? 

Thanks in advance!

Unlike in webstorm, I&#39;m unable to comment JSX code out in `.js` files in the Visual Studio Code.
