ImportError: cannot import name 'abs'

问题

I got problem while doing object detection using tensorflow-gpu

I was follwing the youtube tutorials :https://www.youtube.com/watch?v=Rgpfk6eYxJA

I'm trying to detect object using tensorflow-gpu with virtual environment.

I added python, cuda, tensorflow to system environment variables, and also did make training models with labels.

I converted xml labels to csv using xml_to_csv.py.

The problem is when I try to generate tfrecord using generate_tfrecord.py, that error appear. Please help

Here's the code

(tensorflow) C:\Users\ice305\tensorflow\models\research\object_detection>python generate_tfrecord.py --csv_input=images\train_labels.csv --image_dir=images\train --output_path=train.record

I don't understand what 'abs' is. Please help

This worked for me in ubuntu 18.0.4

pip uninstall tensorflow protobuf --yes
find $CONDA_PREFIX -name "tensorflow" | xargs -Ipkg rm -rfv pkg
pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-1.9.0-cp36-cp36m-linux_x86_64.whl --no-cache-dir

Solution found from GitHub: ImportError: cannot import name 'abs' #20778.

回答2:

OS : Ubuntu 18.04.1

Python Version 3.6

Solution :

Uninstalled tensorflow 1.10

python3 -m pip uninstall tensorflow

Re-installed it again

python3 -m pip install tensorflow==1.8.0

This issue is created cause of older versions of tensorflow dependencies like protobuff and others which gets installed during tensorflow installation, So if you wanna use tensorflow 1.10 you have to uninstall rest of the dependencies or upgrade them.

In case you want to install 1.10.1 then you have to remove these packages

absl-py
astor
gast 
grpcio 
markdown 
numpy 
protobuf 
setuptools 
six 
tensorboard 
tensorflow 
termcolor 
werkzeug 
wheel
protobuf

then do sudo python3 -m pip uninstall tensorflow In case a tensorflow is installed in root user then install it using python3 -m pip install tensorflow --user --no-cache

IF you still face this problem then repeat all the steps above and do find ~/ -name tensorflow and delete every folder that pops up and retry installation.

回答3:

It seems to be a problem if there is a previous installation of tensorflow available. These steps seems to solve the problem.

1) uninstalling tensorflow 2) uninstalling protobuf 3) reinstalling tensorflow (which should come along with the correct protobuf version.

Also need to go to

C:\Program Files (x86)\Microsoft Visual Studio\Shared\Anaconda3_64\Lib\site-packages

and delete all tensorflow related folders

If you use Win10+cuda_10.0+cuDNNv7.4.2.24, follow this will help you！

uninstall all tensorflow and keras related.
uninstall all protobuf related.
delete tensorflow, keras, protobuf related folds in your 'Anaconda3_install_path'\Lib\site-packages, e.g.E:\ProgramData\Anaconda3\Lib\site-packages.
install tensorflow and keras showed below in picture.

I encountered the same error messages while trying seq2seq tutorial. I used tensorflow-cpu, python3.6, Anaconda3 and Ubuntu16.04.

The problem was that the path of tensorflow was not variable on my PC. I couldn't import tensorflow, though I could a few hours before. Try "import tensorflow" on python interactive shell. If you cannot import it, your problem would be the same as mine.

How to solve the problem was deleting everything about tensorflow on your computer and re-install them.

By the way, 'abs' is a function defined in the following file: ~/anaconda3/envs/tensorflow/lib/python3.6/site\ -packages/tensorflow/python/keras/_impl/keras/backend.py

And after re-installing tensorflow, I don't know why, "_impl" directory was disappeared.

Suggested solution on the following link worked for me

https://github.com/tensorflow/tensorflow/issues/20778#issuecomment-410962482

The full solution to this issue is to clean up all TF installation files from your system. Here is how to do that. Run the following first:

$ pyhthon
> import tensorflow as tf
> tf.__file__
'path/to/your/python/installation/site-packages/tensorflow/__init__.pyc'

From the above command, you need to go and remove the folder

path/to/your/python/installation/site-packages/tensorflow

Finally, you need to run

$ pip uninstall tensorflow # Also add -gpu if you installed the GPU version
$ pip install tensorflow # Also add -gpu if you installed the GPU version

Then it should work.

回答7:

Had same problem in windows 10 when installing using anaconda Navigator and selecting all packages available for tensorflow and keras.

Solution was to clean up and install from command line, using "conda install" selecting only "gpu" packages:

conda remove keras*
conda remove tensorflow*
conda remove protobuf 
pip uninstall tensorflow*
pip uninstall protobuf
conda install tensorflow-gpu
conda install keras-gpu

回答8:

This is because that you have install some library and some dependencies of the tensorflow had changes by the installed library.

do the following command it will solve the problem

sudo pip install --upgrade tensorflow-gpu
