我正在尝试在Google Colab笔记本中安装tsne库。 基于其他问题，我尝试安装以下内容无济于事：
!apt-get install libblas-dev libatlas-base-dev libxml2-dev libxslt1-dev gcc python-dev build-essential autoconf libtool pkg-config python-opengl python-imaging python-pyrex python-pyside.qtopengl idle-python2.7 qt4-dev-tools qt4-designer libqtgui4 libqtcore4 libqt4-xml libqt4-test libqt4-script libqt4-network libqt4-dbus python-qt4 python-qt4-gl libgle3 python-dev
!easy_install greenlet
!easy_install gevent
我收到以下错误：

我正在尝试在Google Colab笔记本中安装tsne库
看起来像一些 Debian 或 Ubuntu 操作系统。 Ubuntu 18.04、python2和python3 的例子：
sudo apt install g++-5
cd tsne-0.1.7/
export CC=gcc-5
python setup.py build
python3 setup.py build
sudo su
export CC=gcc-5
python setup.py install
python3 setup.py install
exit
find /usr/local/lib/ -iname "*tsne*"
/usr/local/lib/python2.7/dist-packages/tsne-0.1.7-py2.7-linux-x86_64.egg
/usr/local/lib/python3.6/dist-packages/tsne-0.1.7-py3.6-linux-x86_64.egg
/usr/local/lib/python3.6/dist-packages/tsne-0.1.7-py3.6-linux-x86_64.egg/tsne
注意：一些C文件似乎包含旧代码，因此gcc-5。C++代码适用于 g++-7。
sudo pip install tsne
Requirement already satisfied: tsne in ./python2.7/dist-packages/tsne-0.1.7-py2.7-linux-x86_64.egg
sudo pip3 install tsne
Requirement already satisfied: tsne in ./python3.6/dist-packages/tsne-0.1.7-py3.6-linux-x86_64.egg
注2：参考 https://github.com/danielfrg/tsne → →
Scikit-learn v0.17包含TSNE算法，您可能应该 使用它们而不是这个。
编辑：这里的罪魁祸首似乎是easy_install：如果您使用过$ sudo pip3 install greenlet gevent则不需要/安装tsne。
