linux - python ImportError: No module named '***'

Question

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 np
ImportError: 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.py
Traceback (most recent call last):
  File "CNN_sentence_tensorflow-master/sentence_classfier_with_tensorflow.py", line 13, in <module>
import tensorflow as tf
ImportError: 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$ python
Python 2.7.12 (default, Nov 19 2016, 06:48:10)

>>> import numpy as np
>>> import tensorflow as tf
