pip installl tsne doesn't work
<p>I couldn't install tsne package on my Windows machine. I followed the instruction <a href="https://github.com/danielfrg/tsne/blob/master/README.md" rel="nofollow">here</a> to install tsne packages for Python. But either <code>pip install tsne</code> or <code>pip install git+https://github.com/danielfrg/tsne.git</code> works. The error massage is </p>

<p>I am using Anaconda for python and I installed Visual C++ compiler for Windows too.</p>

<p>I am sorry if you've already tried this, but i couldn't see what you typed into the command prompt to get that error.</p>

<p>If you dont have your path variable set to pip, then type this in (just alter the path if python is in a different directory) and remember its case sensitive!</p>

<pre><code>C:\Python34\Scripts\pip install LIBRARY_NAME
</code></pre>

python pip
