Python ImportError: No module named '***' 错误,pythonimporterror,采用virtualenv


采用virtualenv方式安装tensorflow之后,在sitepackage有tensorflow包,跑官方例子没有问题,自己跑Github上的例子时候,显示

File "/home/idc/tensorflow/multi-class-text-classification-cnn-master/data_helper.py", line 3, in <module>import numpy as npImportError: No module named 'numpy'

跑其他例子显示:

(tensorflow) idc@idc-Hi-Fi-Z77X:~/tensorflow$ sudo python CNN_sentence_tensorflow-master/sentence_classfier_with_tensorflow.pyTraceback (most recent call last):  File "CNN_sentence_tensorflow-master/sentence_classfier_with_tensorflow.py", line 13, in <module>import tensorflow as tfImportError: No module named tensorflow

但是在交互环境下import都没有问题:

(tensorflow) idc@idc-Hi-Fi-Z77X:~/tensorflow/multi-class-text-classification-cnn-master$ pythonPython 2.7.12 (default, Nov 19 2016, 06:48:10) [GCC 5.4.0 20160609] on linux2Type "help", "copyright", "credits" or "license" for more information.>>> import numpy as np>>> import tensorflow as tf>>>     

你可能进入了假的虚拟环境。

sudo python demo.py和python demo.py不一样,sudo一般代表系统默认的python环境

[~]$ which python/usr/local/bin/python[~]$ sudo which python/usr/bin/python
