问题描述
我正在尝试为python3安装Biosig，但出现以下错误：
nahuel@nahuel-Notebook:~/Documents/TESIS/biosig-2.0.6$ python3 -c "import biosig"
Segmentation fault (core dumped)
我有Linux Mint 19 Tara和Python 3.7.5
我通过以下方式安装了它：
nahuel@nahuel-Notebook:~$ python3 -m pip install --no-cache-dir https://pub.ist.ac.at/~schloegl/biosig/prereleases/Biosig-2.0.6.tar.gz

并编译源代码：
make python
make -C biosig4c++/python build
make -C biosig4c++/python release
pip3 install biosig4c++/python/dist/Biosig-2.0.5.tar.gz
两个错误：

我尝试调试：
nahuel@nahuel-Notebook:~/Documents/TESIS/bcitp$ python -Xfaulthandler -c "import biosig"

我安装了推荐的软件包：
---运行时推荐的软件包---
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
我还安装了libbiosig-dev
奇怪的是biosig在python2中工作
我解决了这个问题：
sudo pip2卸载biosig sudo pip3卸载biosig sudo apt-get删除biosig-dev biosig1
然后重新安装 ./configure && make &&进行安装
解决方法
欢迎使用StackOverflow！ biosig Python软件包取决于已编译的C / C ++ libbiosig。您可以先安装该软件包（例如，使用程序包管理器安装），然后重试pip install命令。
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
我不确定libbiosig-dev是否在Linux Mint中可用，但在Debian（Mint所基于的）中是否可用。
