錯誤導入Theano

安裝Python，numpy的，SciPy的和theano到〜/。本地後，我試圖導入theano但它拋出一個錯誤：錯誤導入Theano

>>> import theano

我在紅帽箱安裝：

$ cat /proc/version 
Linux version 2.6.32-279.14.1.el6.x86_64 ([email protected]) (gcc version 4.4.6 20120305 (Red Hat 4.4.6-4) (GCC)) #1 SMP Tue Nov 6 23:43:09 UTC 2012

我該怎麼辦......？

您沒有正確構建python。它沒有用-fPIC參數編譯。看看如何用共享庫來編譯python。

編輯：您需要編譯蟒蛇是這樣的：

./configure --enable-shared 
make 
make install

謝謝！我還需要運行'export LD_LIBRARY_PATH =/home/minh.lengoc/.local/lib：$ LD_LIBRARY_PATH'使其工作。 –

@ngọcminh.oss：您的lib目錄中有什麼，需要將其添加到LD_LIBRARY_PATH中？ – hlin117

沒關係，在這裏找到答案：http://stackoverflow.com/questions/7880454/python-executable-not-finding-libpython-shared-library – hlin117

我使用的virtualenv在Ubuntu 16.04，並與pyenv install 3.6.1安裝Python之前，我跑以下命令以確保蟒蛇是建立與該子卡標誌：

export CONFIGURE_OPTS="OPT=\"-fPIC\""

然後，我能夠安裝並正確運行theano。
