ta-lib replit python install problem, ERROR: No matching distribution found for talib-binary


I use it on my windows machine by downloading its binary. I also use it in Heroku from its herokus build pack. I don't know what operating system replit use. But I try every possible commed like.

!pip install ta-lib

!pip install talib-binary

It's not working with replit. I thought it work like google co-lab but its not the same.

can anyone use TA-LIB with replit. if so. How you install it?


Solution

  • Getting TA-Lib work on Replit (by installing it from sources)

    Create a new replit with Nix toolset with a Python template. In main.py write:

    import talib
    print (talib.__ta_version__)
    

    This will be our test case. If ta-lib is installed the python main.py (executed in Shell) will return something like:

    $ python main.py 
    b'0.6.0-dev (Jan  1 1980 00:00:00)'
    

    We need to prepare a tools for building TA-Lib sources. There is a replit.nix file in your project's root folder (in my case it was ~/BrownDutifulLinux). Every time you execute a command like cmake the Nix reports that:

    cmake: command not installed. Multiple versions of this command were found in Nix.
    Select one to run (or press Ctrl-C to cancel):
    
    cmake.out
    cmakeCurses.out
    cmakeWithGui.out
    cmakeMinimal.out
    cmake_2_8.out
    

    If you select cmake.out it will add a record about it into the replit.nix file. And next time you call cmake, it will know which cmake version to launch. Perhaps you may manually edit replit.nix file... But if you're going to add such commands in a my way, note that you must execute them in Shell in your project root folder as replit.nix file is located in it. Otherwise Nix won't remember your choice.

    After all my replit.nix file (you may see its content with cat replit.nix) content was:

    { pkgs }: {
      deps = [
        pkgs.libtool
        pkgs.automake
        pkgs.autoconf
        pkgs.cmake
        pkgs.python38Full
      ];
      env = {
        PYTHON_LD_LIBRARY_PATH = pkgs.lib.makeLibraryPath [
          # Needed for pandas / numpy
          pkgs.stdenv.cc.cc.lib
          pkgs.zlib
          # Needed for pygame
          pkgs.glib
          # Needed for matplotlib
          pkgs.xorg.libX11
        ];
        PYTHONBIN = "${pkgs.python38Full}/bin/python3.8";
        LANG = "en_US.UTF-8";
      };
    }
    

    Which means I executed libtool, autoconf, automake and cmake in Shell. I always choose a generic suggestion from Nix, without a specific version. Note: some commands may report errors as we executing them in a wrong way just to add to a replit.nix.

    3. Once build tools are set up we need to get and build TA-Lib C library sources. To do that execute in Shell:

    git clone https://github.com/TA-Lib/ta-lib.git
    

    then

    cd ta-lib/
    
    libtoolize
    autoreconf --install
    
    ./configure
    

    If configure script is completed without any problems, build the library with:

    make -j4
    

    It will end up with some compilation errors, but they are related to some additional tools which are used to add new TA-Lib indicators and build at the end, but not the library itself. The library will be successfully compiled and you should be able to see it with:

    $ ls ./src/.libs/
    libta_lib.a   libta_lib.lai  libta_lib.so.0
    libta_lib.la  libta_lib.so   libta_lib.so.0.0.0
    

    Now we have our C library built, but we can't install it to a system default folders. So we have to use the library as is from the folders where it was build. All we need is just one more additional preparation:

    mkdir ./include/ta-lib
    cp ./include/*.h ./include/ta-lib/
    

    This will copy a library headers to a subfolder, as they are designed to be used from a such subfolder (which they don't have due to impossibility to perform the installation step).

    4. Now we have TA-Lib C library built and prepared to be used locally from its build folders. All we need after that - is to compile the Python wrapper for it. But Python wrapper will look for a library only in system default folders, so we need to instruct it where our library is.
    To do this, execute pwd and remember the absolute path to your project's root folder. In my case it was:
    /home/runner/FormalPleasedOffice

    Then adjust the paths (there are two) in a following command to lead to your project path: TA_INCLUDE_PATH=/home/runner/FormalPleasedOffice/ta-lib/include/ TA_LIBRARY_PATH=/home/runner/FormalPleasedOffice/ta-lib/src/.libs/ pip install ta-lib

    This is one line command, not a two commands.If the paths would be shorter it would look like:
    TA_INCLUDE_PATH=/path1/ TA_LIBRARY_PATH=/path2/ pip install ta-lib.

    After execution of this command the wrapper will be installed with two additional paths where it will look for a library and its header files.

    That's actually all. An alternative way would be to clone the wrapper sources, edit its setup.py and install wrapper manually. Just for the record this would be:

    cd ~/Your_project
    git clone https://github.com/mrjbq7/ta-lib.git ta-lib-wrapper
    cd ta-lib-wrapper
    

    Here edit the setup.py. Find the lines include_dirs = [ and library_dirs = [ and append your paths to these lists. Then you just need to:

    python setup.py build
    pip install .
    

    Note the dot at the end.

    5. Go to the project's folder and try our python script:

    $python main.py
    b'0.6.0-dev (Jan  1 1980 00:00:00)'
    

    Bingo!
