問題描述

采用virtualenv方式安裝tensorflow之后，在sitepackage有tensorflow包，跑官方例子沒有問題，自己跑Github上的例子時候，顯示

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’

跑其他例子顯示：

(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

但是在交互環境下import都沒有問題：

(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>>>

問題解答

sudo python demo.py和python demo.py不一樣，sudo一般代表系統默認的python環境

[~]$ which python/usr/local/bin/python[~]$ sudo which python/usr/bin/python回答2：

你可能進入了假的虛擬環境。
