Pip安装Keras和TensorFlow缺少软件包？

Question

I used pip to install keras and tensorflow, yet when I import subpackages from keras, my shell fails a check for PyBfloat16_Type.tp_base.

I tried uninstalling and reinstalling tensorflow, but I don't know for certain what is causing this error.

from keras.models import Sequential
from keras.layers import Dense

3.7.0 (v3.7.0:1bf9cc5093, Jun 27 2018, 04:59:51) [MSC v.1914 64 bit (AMD64)]

Can someone help me solve this issue?

Answer 1

You may try to downgrade python to 3.6 (I know some people have troubles with tensorflow and keras using python 3.7). One simple way is to download anaconda, create a new environment with python 3.6, then install tensorflow and keras.

conda create -n myenv python=3.6

conda activate myenv

pip3 install tensorflow

pip3 install keras

Answer 2

You have a few options to try:

First, try to uninstall and re-install the TensorFlow and see whether the problem is resolved or not (replace tensorflow with tensorflow-gpu in the following commands if you have installed the GPU version):

pip uninstall tensorflow 

pip install --no-cache-dir tensorflow

If the problem is not resolved, try to do the same thing with numpy :

pip uninstall numpy

pip install --no-cache-dir numpy

Hopefully, one of these two would resolve the problem.
