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

问题描述

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>>>

问题解答

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回答2：

你可能进入了假的虚拟环境。
