installation errors

[SND8041]

Hi, I have python27 installed on Windows 10, the packages: networkx, scipy, numpy and all that are required are installed already. Trying the following command, after downloading pracmln in a folder, say C:\pracmln:

C:\pracmln>python setup.py install Traceback (most recent call last): File "setup.py", line 7, in pip.main(['install', 'appdirs']) AttributeError: 'module' object has no attribute 'main'

Then I used pip:

C:\pracmln>pip install pracmln Collecting pracmln Using cached https://files.pythonhosted.org/packages/79/c8/757ecbf41fd85a942c9c1fe3d6087b845969a70ef95f23cca1bb746e861c/pracmln-1.2.3.tar.gz Complete output from command python setup.py egg_info: Traceback (most recent call last): File "", line 1, in File "c:\users!snd804\appdata\local\temp\pip-install-_ftvu1\pracmln\setup.py", line 7, in pip.main(['install', 'appdirs']) AttributeError: 'module' object has no attribute 'main'

----------------------------------------

Command "python setup.py egg_info" failed with error code 1 in c:\users!snd804\appdata\local\temp\pip-install-_ftvu1\pracmln\

What am I missing? Can you guide?

Thanks

Syed

Please check your version of pip. I have no idea about Windows, but on my computer:

... $ pip -V
pip 10.0.1 from /home/ ... /python2.7/site-packages/pip (python 2.7)

If your version of pip is 10, then please note that pip doesn't support main anymore. A quick fix is to downgrade your pip version to 9.0.3 (See here for details, here for solution)

To do this, execute the following command (or it's Windows equivalent)

$ python -m pip install --upgrade pip==9.0.3
Collecting pip==9.0.3
.
.
.
Successfully installed pip-9.0.3
**You are using pip version 9.0.3, however version 10.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.**

Ignore the warning at the end.

To ensure that this will work, the pip version check must tell you that pip has been rolled back to 9.0.3:

$ pip -V
pip 9.0.3 from /home/ ... /python2.7/site-packages (python 2.7)

Now you can proceed to install PracMLN and its requirements. Hope this helps!

Hello,

Thanks for your reply. Following your suggestions I uninstalled the pip version 10 and installed the one you mentioned. Then I installed PracMLN, everything went good during the installation but when I ran the command C:\Python27\mlnlearn I received the following message:

C:\Python27>mlnlearn Traceback (most recent call last): File "c:\python27\lib\runpy.py", line 174, in _run_module_as_main "main", fname, loader, pkg_name) File "c:\python27\lib\runpy.py", line 72, in _run_code exec code in run_globals File "C:\Python27\Scripts\mlnlearn.exe__main.py", line 5, in File "c:\python27\lib\site-packages\pracmln\init.py", line 21, in from mln.base import MLN File "c:\python27\lib\site-packages\pracmln\mln\init.py", line 27, in from base import MLN File "c:\python27\lib\site-packages\pracmln\mln\base.py", line 27, in from dnutils import logs, ifnone, out File "c:\python27\lib\site-packages\dnutils\init__.py", line 10, in from .signals import add_handler, rm_handler, enablectrlc File "c:\python27\lib\site-packages\dnutils\signals.py", line 11, in SIGKILL = signal.SIGKILL AttributeError: 'module' object has no attribute 'SIGKILL'

I am new in Python, and MLN so please accept my apologies for asking a kind of a silly nontechnical question.

Hi Syed,

There are no silly questions.

Looks like your setup was successful. If I understand correctly, your issue is the same as #13. This is a Windows-specific error, and unfortunately I am not aware of any solution yet. It looks like dnutils is actually not cross-platform, and doesn't work on Windows. However, I am unsure if this is really the case, since I can't find it being reported elsewhere on the internet.

Unfortunately I don't use Windows myself, and can thus offer very little by way of advice, but there must be some possible workaround that you could discover.

I'm getting a similar attribute error when I try to import pracmln in a Jupyter notebook on a MacBook Pro.

Hi Thomas I moved to Ubunto because I remained unable to solve it on Windows. Its pretty much straightforward to installation Ubunto alongside a Windows platform.

Best of luck, Syed

I'm on a Mac. I cannot seem to get it to work.

I see that ProbCog has examples for running inference from Python. I can run ProbCog okay for the most part on my Mac.

What is the relationship between PracMLN and ProbCog? Does PracMLN simply provide a python package wrapper for ProbCog? Is ProbCog being maintained actively?

Also on a Macbook, can not get it to work
