Re: compiled TF from source. ImportError: cannot import name 'resnet'

+Yifei Feng do you know what can cause this?

I am trying to compile Tensorflow from source, because of the AVX issue https://github.com/tensorflow/tensorflow/issues/19584

I'm running Linux Mint on Fitlet2 MiniPC. "uname -a" says:

Linux john-fitlet2 4.15.0-55-generic #60-Ubuntu SMP Tue Jul 2 18:22:20 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

"cat /proc/cpuinfo" says: Intel(R) Celeron(R) CPU J3455 @ 1.50GHz

Following https://www.tensorflow.org/install/source I did the commands shown below. The "bazel build" line took about 24 hours, and seemed to succeed.

sudo apt install python3-dev python3-pip
pip3 install -U pip six numpy wheel setuptools mock future>=0.17.1
pip3 install -U keras_applications==1.0.6 --no-deps
pip3 install -U keras_preprocessing==1.0.5 --no-deps

git clone https://github.com/tensorflow/tensorflow.git
cd tensorflow
./configure
bazel build --local_ram_resources=2048 --config=opt //tensorflow/tools/pip_package:build_pip_package
./bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg
sudo -H pip3 install /tmp/tensorflow_pkg/tensorflow-1.14.0-cp36-cp36m-linux_x86_64.whl

However my installation has some problem, as you see below.

Python 3.6.8 (default, Jan 14 2019, 11:02:34)
[GCC 8.0.1 20180414 (experimental) [trunk revision 259383]] on linux

    from keras_applications import resnet
ImportError: cannot import name 'resnet'

 After seeing this error, I then tried:

sudo -H pip3 install --upgrade keras keras-applications

however Ithe same error when loading tensorflow in Python3 results. Any suggestions would be welcome, thank you!

Hey Alex,

you can use keras_applications module directly to import all ResNet, ResNetV2 and ResNeXt models.

Check this out https://keras.io/applications/

I deleted my original question right after posting, after I saw a notice in this forum that bug reports etc. should go to StackOverflow instead of here. But I guess it was too late! So I put the question here https://stackoverflow.com/questions/57275893/tf-compileinstall-for-python3-cannot-import-name-resnet but I'll still welcome any assistance here :-)

Simply opening Python3 and typing "import keras"  has same error: ImportError: cannot import name 'resnet'
So there's something just plain wrong with my install, but I'm too much of a newbie to understand what.

FWIW: now solved. I had some still-unknown conflict or misconfiguration. I just installed the same .whl file into a virtual environment, and it's all good now.
