pyOpt for python 3 install error
<p>I find a pyOpt package compatible for python3:
<a href="https://github.com/madebr/pyOpt" rel="nofollow noreferrer">https://github.com/madebr/pyOpt</a></p>

<p>I install it using a command window like bellow:
    <code>python setup.py install</code>
there's are some warnings or errors in the installation process:</p>

<ol>
<li><p><code>cobylamodule.obj : error LNK2001: unresolved external symbol pyflush_</code> and some nearly the same instruction like this </p></li>
<li><p><code>File "C:\Users\tsing\Anaconda3\Lib\site-packages\pyOpt\pySNOPT\pySNOPT.py", line 422
if mode &lt;&gt; 0 and self.h_start:
         ^
SyntaxError: invalid syntax
</code></p></li>
</ol>

<p>though it looks like the install is nearly a success, after that I tried to run some problem but faced the same error:</p>

<pre><code>Traceback (most recent call last):
</code></pre>

<p><code>File "C:/Users/tsing/OneDrive/Python Code/pyOpt-for3/pyOpt-master/examples/tp037_resetbyTsing.py", line 28, in &lt;module&gt;
    from pyOpt.pySLSQP import SLSQP
ImportError: cannot import name 'SLSQP'</code></p>

<p>there are only 2 optimizer writen in python can run, but when I look up the optimizer file in the anaconda lib like:<code>C:\Users\tsing\Anaconda3\Lib\site-packages\pyOpt\pySLSQP</code> I find that there's a 'source' file missing compared with the original file unziped from the download pyOpt,and that file contains the real solver like pySLSQP </p>

<p>My operation system is X64 WIN10</p>

<p>I just don't know what's wrong with this, could someone give me some suggestion?</p>
