| Post subject: | Problems with library in Ipython. |
Hi all, Most likely is a silly question but I am having problems using xalglib.py My OS is Linux I am using Python 2.7 I downloaded the alglib-3.9.0.ipython.gpl file and extracted all the files in a folder. Within the ipython folder I can find the xalglib.py and check.py files. If I run python check.py I get the following error: Traceback (most recent call last): File "check.py", line 1, in <module> import xalglib File "/alglib_folder/ipython/xalglib.py", line 25, in <module> import clr ImportError: No module named clr I also think that I will have problems with the next import: "import System" Those libraries do not seem to be available for Ipython... What am I doing wrong? Thanks for your help, Hector |

Did you used CPython or IPython? |

Error messages like yous are typical when IPython program is executed from CPython. |

Hello, First of all, thank you very much for your replies. I do not have installed CPython in my system as far as I know. If I just run in a terminal window "python check.py" then I assume that I am using the Python from the system, that is Python 2.7.9 and I get the aforementioned error. If I open an Ipython session and I type "import xalglib.py" and hit "enter" then I get the same error. I have the same problem if I run both files in an Anaconda environment. In fact, both "clr" and "System" libraries seem to be available in a .NET environment and not in linux by default. I would really appreciate if you can help me to solve this problem. Thanks, Hector |

Hi again, Just in case, I have tried to use the alglib-3.9.0.cpython.gpl file that according to the web page "can be used from Python 2.x and 3.x". Once I have extracted its content in a folder, I can find the following "relevant" files: core (it's a folder) xalglib.py setup.py If I run "python setup.py" i get the following error: "ALGLIB installer: unable to detect ALGLIB shared library". It is "reasonable" because when it tries to copy the shared libraries from the core directory it looks for the core/alglib.so file and that file is not there. In the core folder there are only ".dll" libraries for a Windows environment. Should I have that alglib.so file there? Thanks again, Hector |

Hi, Following step by step the instructions in the cpython manual helped to solve most of the issues. Now I will start using the RBF subpackage. Thanks, Hector |
