即使使用conda安装后也无法安装tensorflow

Question

Hello Stackoverflow people. Merry Christmas!

I'm having trouble with installing tensorflow. I'm using window 10 and I installed tensorflow with this code.

conda create -n tensorflow python=3.6
activate tensorflow
pip install tensorflow

After finishing all installation, I checked if it's installed successfully at the anaconda prompt

(tensorflow) > python
>>> import tensorflow as tf
>>> hello = tf.constant("Hello, tensorflow")
>>> sess = tf.Session()
>>> print(sess.run(hello))

It printed out "Hello, tensorflow" very well. But after that when I tried to import tensorflow or keras on my jupytor notebook or spyder, it threw error.

No module named 'tensorflow'

The version of python is 3.7 so I tried to downgrade it.

conda install python=3.6

But still, it doesn't work. What should I do? I just guess downgrading didn't work well, cause I still can see 'Spyder(Python=3.7)' at the right top of the spyder window.

Please Help!

I think you just use another version of Python so you can use this command to get the path of tensorflow, for some platform the default pip is for Python2, so maybe you will get:

C:\Users\Nick>pip show six
Name: six
Version: 1.11.0
Summary: Python 2 and 3 compatibility utilities
Home-page: http://pypi.python.org/pypi/six/
Author: Benjamin Peterson
Author-email: benjamin@python.org
License: MIT
Location: c:\python27\lib\site-packages
Requires:

Also from the doc Work with multiple versions of Python installed in parallel .

You can try this:

On Linux, Mac OS X, and other POSIX systems, use the versioned Python commands in combination with the -m switch to run the appropriate copy of pip:

python2   -m pip install SomePackage  # default Python 2
python2.7 -m pip install SomePackage  # specifically Python 2.7
python3   -m pip install SomePackage  # default Python 3
python3.4 -m pip install SomePackage  # specifically Python 3.4

Appropriately versioned pip commands may also be available.

On Windows, use the py Python launcher in combination with the -m switch:

py -2   -m pip install SomePackage  # default Python 2
py -2.7 -m pip install SomePackage  # specifically Python 2.7
py -3   -m pip install SomePackage  # default Python 3
py -3.4 -m pip install SomePackage  # specifically Python 3.4

If you have a broken pip on Anaconda, you can follow these steps:

1. Find pip folder under "../Anaconda3/Lib/site-packages/", delete it manually.
2. In Anacoda prompt do : conda uninstall pip
3. Install pip using your familiar way. Eg: conda install -c anaconda pip

Hope this helps.
