使用tensorflow遇見的坑1

坑1描述：

安裝了tensorflow-gpu版本以後，在pycharm中用樣例程式碼測試tensorflow是否安裝成功時。出現瞭如下錯誤。

直接的錯誤時：ImportError: libcublas.so.9.0: cannot open shared object file: No such file or directory

Traceback (most recent call last):
  File "/home/wanglei/tensorflow/lib/python3.6/site-packages/tensorflow/python/pywrap_tensorflow.py", line 58, in <module>
    from tensorflow.python.pywrap_tensorflow_internal import *
  File "/home/wanglei/tensorflow/lib/python3.6/site-packages/tensorflow/python/pywrap_tensorflow_internal.py", line 28, in <module>
    _pywrap_tensorflow_internal = swig_import_helper()
  File "/home/wanglei/tensorflow/lib/python3.6/site-packages/tensorflow/python/pywrap_tensorflow_internal.py", line 24, in swig_import_helper
    _mod = imp.load_module('_pywrap_tensorflow_internal', fp, pathname, description)
  File "/home/wanglei/tensorflow/lib/python3.6/imp.py", line 243, in load_module
    return load_dynamic(name, filename, file)
  File "/home/wanglei/tensorflow/lib/python3.6/imp.py", line 343, in load_dynamic
    return _load(spec)
ImportError: libcublas.so.9.0: cannot open shared object file: No such file or directory
 

原因是無法載入libcublas.so檔案，解決辦法應該在edit configurations中配置python的執行環境。加入LD_LIBRARY_PATH,設定路徑/usr/local/cuda/lib64 每次新建一個py檔案都要重新新增，好在可以直接複製，貼上。
