<div dir="ltr">Xin, <div><br></div><div>Unless you have modified your PYTHONPATH variable or your site-packages settings, this command: </div><div><br></div><div>python setup.py install --user </div><div><br></div><div>will not actually install petsc4py in a location visible to your Python installation. Unfortunately, the Python procedures and documentation for "user-local" installations are fairly poor in comparison to the rest of Python's friendliness. I rely on virtualenv to set up an environment that I can just "pip install" into. I recommend using virtualenv, as properly using it can save you a lot of headaches when developing in Python. See this answer on StackExchange to understand how to get set up with virtualenv:</div>
<div><br></div><div><a href="http://stackoverflow.com/a/5177027/122022">http://stackoverflow.com/a/5177027/122022</a></div><div><br></div><div>Once you have created a virtualenv, you can then cd into the directory of code you'd like to use and type:</div>
<div><br></div><div>pip install -e .</div><div><br></div><div>This allows you to modify the code and have those changes reflected when you reload the virtual environment's Python interpreter.</div><div><br></div><div>
If you just need to install once, you can just do:</div><div><br></div><div>pip install .</div><div><br></div><div>or</div><div><br></div><div>python setup.py install</div><div><br></div><div>And the package will be installed into the virtual environment, though you will need to re-install if you make any changes.</div>
