Question

I want to install tensorflow to use Keras LSTM I installed Keras, and i import this lines to my code.

from keras.callbacks import LambdaCallback
from keras.models import Sequential
from keras.layers import Dense, Activation
from keras.layers import LSTM
from keras.optimizers import RMSprop

Error is when runnig the code:

No module named 'tensorflow'

Cmd error when i write "pip install tensorflow" :

ERROR: Could not find a version that satisfies the requirement tensorflow (from versions: none)
ERROR: No matching distribution found for tensorflow

Pip version is 19.3 , python version 3.7

Answer 1

On Windows, you must use Python 3.7.6 (64 bits) to install tensorflow:

C:Program FilesPython-3.7.6-x64> python.exe -m pip install --user tensorflow

Unfortunately, the 32-bit version is not supported by tensorflow and will give you that nasty error:

Could not find a version that satisfies the requirement tensorflow (from versions: none) ERROR: No matching distribution found for tensorflow

A few important notes:

• Install Microsoft Visual C++ Redistributable packages for x64 (2015, 2017, 2019).
• If you have previously installed Python 3.7 for x86, uninstall it from your system and also delete the directory where the x86 packages were stored to avoid a conflict with the new x64 packages that will be placed there. In my machine they were stored at C:\Users\karlphillip\AppData\Roaming\Python\Python37\site-packages.
• Finally, install Python 3.7.6 (x64) and upgrade pip with python -m pip install --user --upgrade pip.
• Now, simply install tensorflow: python -m pip install --user tensorflow
