Tensorflow install fails with "compiletime version 3.5 of module does not match runtime version 3.6"
Solution 1
RuntimeWarning: compiletime version 3.5 of module 'tensorflow.python.framework.fast_tensor_util' does not match runtime version 3.6
This is a known issue, which is got prioritized and likely to be fixed soon. Right now the workaround is to use python 3.5.
UPDATE:
The issue has been fixed in the nightly tensorflow builds: "tf-nightly
and tf-nightly-gpu
now has a python3.6 binary built from scratch for Linux."
I.e., the following command should work with python 3.6:
# tf-nightly or tf-nightly-gpu
pip3 install tf-nightly
Your CPU supports instructions that this TensorFlow binary was not compiled to use: SSE4.1 SSE4.2 AVX
This warning comes from the fact that the default tensorflow distributions are compiled without CPU extensions support (more on this here). If you want to get a CPU optimized tensorflow package, your only option is to build it yourself. It's a bit tedious, but absolutely doable. The build will produce the wheel file, which you can install with just
pip3 install /path/to/the/tensorflow.whl
But if you just want to suppress the warning, this will do:
import os
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2'
Solution 2
I got the same issue and I was able to solve it by installing 1.3 version rather than using 1.4 of tensorflow. Use the following command to do so.
pip3 install tensorflow==1.3.0
Solution 3
Just install 1.3 version of tensorflow. Problem solved.
pip install tensorflow==1.3.0
Solution 4
I encountered the same problem and I fixed it by:
pip install --ignore-installed tensorflow
The problem occurred because I complied a local version of tensorflow (to enable some CPU features) with python 3.5 earlier. I installed python 3.6 recently and the new tensorlfow already supported those CPU features, so I just installed the official version.
Update:
After some update of tensorflow
the approach above doesn't work any more.
Another workaround is using virtual environment such as anaconda to create a python3.5 environment:
conda create -n py35 python=3.5
source activate py35
pip install tensorflow
To work with ipython or jupyter notebook, be sure to install ipykernel inside the virtual environment:
pip install ipykernel
Solution 5
i use tensorflow 1.4.0, meet the same problem. but you can use tensorflow 1.6.0, now.

I tried installing from pip:
pip3 install --user --no-cache https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-1.4.0-cp36-cp36m-linux_x86_64.whl
Then tried importing and got:
Using TensorFlow backend. /usr/lib64/python3.6/importlib/_bootstrap.py:205: RuntimeWarning: compiletime version 3.5 of module 'tensorflow.python.framework.fast_tensor_util' does not match runtime version 3.6 return f(*args, **kwds) 2017-11-10 09:35:01.206112: I tensorflow/core/platform/cpu_feature_guard.cc:137] Your CPU supports instructions that this TensorFlow binary was not compiled to use: SSE4.1 SSE4.2 AVX
Questions:
I don't understand why the wheel says 3.6, but I get the warning about 3.5
I want to compile to optimize for my cpu, so can I use pip to install from source rather than from binary wheel?

Kristada673 over 6 yearsSo, is this warning non-harmful, so that we can afford to suppress it? And if yes, is there any way to permanently suppress it instead of doing
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2'
every time I want to use tensorflow? -
Maxim over 6 years@Kristada673 Yes, it's mentioned in this answer - stackoverflow.com/a/47227886/712995 Do
export TF_CPP_MIN_LOG_LEVEL=2
from the command line -
Kristada673 over 6 yearsI was referring to the warning
RuntimeWarning: compiletime version 3.5 of module 'tensorflow.python.framework.fast_tensor_util' does not match runtime version 3.6
. When I doexport TF_CPP_MIN_LOG_LEVEL=2
, this warning does not go away. Is it non-harmful? If yes, how can I ignore it? And if no, how can I fix it? -
Maxim over 6 years@Kristada673 I see. No, this warning won't go away that easily. It seems not break tf, but certain internal packages won't import, you never know which function may fail. All currently available fixes are in the answer

Z Alward over 6 yearsI also found that by installing a virtual environment with python 3.6.3 then activating the environment before installing tensorflow, the issue was resolved.
$conda create -n tensorflow python=3.6.3 Anaconda --y
$conda update conda
$source activate envname
$conda install tensorflow
