Я пытаюсь установить Biosig для python3, но у меня следующая ошибка:

 nahuel@nahuel-Notebook:~/Documents/TESIS/biosig-2.0.6$ python3 -c "import biosig"
Segmentation fault (core dumped)
  

У меня есть Linux Mint 19 Tara и Python 3.7.5

Я установил его с:

 nahuel@nahuel-Notebook:~$ python3 -m pip install --no-cache-dir https://pub.ist.ac.at/~schloegl/biosig/prereleases/Biosig-2.0.6.tar.gz

а также компиляция исходного кода:

 make python
make -C biosig4c  /python build
make -C biosig4c  /python release

pip3 install biosig4c  /python/dist/Biosig-2.0.5.tar.gz
  

обе одинаковые ошибки:

Я пытаюсь отлаживать:

Я устанавливаю рекомендуемые пакеты:

— Рекомендуемые пакеты во время выполнения —

 sudo apt-get install libb64 tinyxml python-numpy python3-numpy R openjdk-11-jre octave octave-tsa octave-nan

E: Unable to locate package libb64  #but install libb64-dev
E: Unable to locate package tinyxml #but install libtinyxml-dev
E: Unable to locate package R       #not installed
  

Я также установил libbiosig-dev

что-то странное в том, что biosig работает в python2

Я исправляю проблему:

sudo pip2 удалить biosig sudo pip3 удалить biosig sudo apt-get удалить biosig-dev biosig1

и переустановите ./configure amp;amp; make amp;amp; make install

Добро пожаловать в StackOverflow! Пакет biosig Python зависит от скомпилированного C / C libbiosig . Вы можете сначала установить это (например, с помощью вашего менеджера пакетов), а затем повторить pip install команду.

 apt-get update
apt-get install libbiosig-dev  # Answer yes to install
python3 -m pip install --no-cache-dir https://pub.ist.ac.at/~schloegl/biosig/prereleases/Biosig-2.0.6.tar.gz
python3 -c 'import biosig'  # Test that import works
  

Я не уверен, libbiosig-dev доступен ли он в Linux Mint, но он доступен в Debian (на котором основан Mint).
