install without conda, problem.

[David van Leeuwen]

Hello, 

I realize installation is supposed to happen through conda, but I am not using conda. 

When I try to install using `pip2 install bob`, the setup script bails out at:

```

    Complete output from command python setup.py egg_info:

    Traceback (most recent call last):

      File "<string>", line 1, in <module>

      File "/private/var/folders/3n/s84ddz9d6n5g9s86wjl3pdr80000gp/T/pip-build-nbcgPv/bob.ap/setup.py", line 42, in <module>

        bob_packages = bob_packages,

      File "/usr/local/lib/python2.7/site-packages/bob/blitz/extension.py", line 52, in __init__

        BobExtension.__init__(self, *args, **kwargs)

      File "/usr/local/lib/python2.7/site-packages/bob/extension/__init__.py", line 301, in __init__

        bob_includes, bob_libraries, bob_library_dirs, bob_macros = get_bob_libraries(self.bob_packages)

      File "/usr/local/lib/python2.7/site-packages/bob/extension/__init__.py", line 193, in get_bob_libraries

        pkg = importlib.import_module(package)

      File "/usr/local/Cellar/python/2.7.13/Frameworks/Python.framework/Versions/2.7/lib/python2.7/importlib/__init__.py", line 37, in import_module

        __import__(name)

    ImportError: No module named sp

```

whereas, in fact, `sp` is installed.  

Any ideas what might be going wrong?

Cheers,

Hi,

Please take a look at this page:
https://www.idiap.ch/software/bob/docs/bob/bob/stable/source.html
and let me know if you still have problems.

If pip fails, maybe you can try buildout?

Thanks,

Amir

This is a known issue which is fixed in the master branch of bob.extension.

To checkout bob from source, please follow the buildout guide that I sent earlier. You can ignore the conda steps in that guide assuming you are installing the dependencies with another package manager.

https://www.idiap.ch/software/bob/docs/bob/docs/master/bob.extension/doc/index.html#bob-extension

Conda is a binary package manager. Installing bob with conda is done without any compilation. Although I think our conda installation instructions are broken temporarily.

Best,

Amir

Hello, 

I am not sure if I understand the instructions correctly.  But on a debian-9 system I got stuck at 

```sh

pip install bob.extension

apt-get install libboost-dev blitz++

pip install bob.blitz

...

    /usr/include/c++/6/cstdlib:75:25: fatal error: stdlib.h: No such file or directory

     #include_next <stdlib.h>

```

so dependencies still are a nightmare.  I get the impression that conda is a package managing system for python which doesn't fit in with debian, so I want to stay away from that a little longer, if possible. 

In the end, I started this because I am interested in the roc convex hull implementation of the EER in bob.measure, but installing that comes with a long list of non-trivial to install dependencies.
