ImportError: No module named nets #1842

10183308 · 2017-07-03T07:42:28Z

when I enter : python object_detection/builders/model_builder_test.py

it shows the wrong : ImportError: No module named nets

could you help me?

thank you very much

heroinlin · 2017-07-04T01:10:16Z

Look at Installation！！！
When running locally, the tensorflow/models/ and slim directories should be appended to PYTHONPATH. This can be done by running the following from tensorflow/models/:

From tensorflow/models/

export PYTHONPATH=$PYTHONPATH:pwd:pwd/slim
nets and deployment modules belong to slim

heroinlin · 2017-07-04T02:55:53Z

'pwd' is the path of models folder. Try to set "pwd:pwd/slim" with "/media/media_share/linkfile/models: /media/media_share/linkfile/models/slim". 2017-07-04 9:32 GMT+08:00 10183308 <[email protected]>:

Ah, it is the problem of "path"! I have trying for several days. When I added in the program code:
"import sys
print(sys.path)
sys.path.append("/usr/local/lib/python2.7/dist-packages/tensorflow/contrib/slim")
print(sys.path)"
It works! For the nets.py in directory"/usr/local/lib/python2.7/dist-packages/tensorflow/contrib/slim"

heroinlin · 2017-08-02T02:45:06Z

Congratulate to work it well.You can find the slim folder in models folder, and nets folder in the slim folder.I work it on windows, like this:
.
so I just add this slim to the path.on the linux, you can try it similarly.

FlashSnail · 2017-08-21T09:39:37Z

I think it's a trick.... in the document, it said

export PYTHONPATH=$PYTHONPATH:'pwd':'pwd'/slim

pwd is your local path, however, you should keep mark like this : 'local path':'localpath'/slim
it works on my computer. 哇，喷火龙唉！

aweichina · 2017-10-17T00:52:11Z

sudo gedit ~/.bashrc #open bashrc file
#then add this new line to the end of your bashrc file
export
PYTHONPATH=$PYTHONPATH=/home/hri/tensorflow/models/research:/home/hri/tensorflow/models/research/slim
#then restart then bashrc to make it work
source ~/.bashrc
#you can change the path to your own!

kil0watt · 2018-04-02T13:05:59Z

I encountered the same problem on windows. What I did was, I just copied the entire nets folder from slim directory to C:\Python\Python35\Lib\site-packages\object_detection-0.1-py3.5.egg (where I installed object_detection API). Then the error is completely gone.

JustinAsdz · 2018-08-14T05:55:36Z

I have the same problem and I go to the tensorflow's github for information
You can never figure it out that I solve this by simply copy the code below from the net page
export PYTHONPATH=$PYTHONPATH:pwd:pwd/slim

Note that it's ` instead of ' around the key pwd
That's my problem, hope it's helpful to you

kochsnow · 2018-08-30T12:17:43Z

I add export PYTHONPATH="$PYTHONPATH:tensorflow/models/research:/tensorflow/models/research/slim" in my .bashrc file, then source ~/.bashrc file, but I still has this problem. someone can tell me whiy

jeremiahharbach · 2018-08-30T18:14:14Z

It looks like your paths are wrong (unless you have a directory called "tensorflow" at the root of your filesystem, in which case you are missing a '/' at the beginning of your first path)

try to include the absolute path. e.g.:
export PYTHONPATH="$PYTHONPATH:/home/kochsnow/tensorflow/models/research:/home/kochsnow/tensorflow/models/research/slim"

aweichina · 2018-09-06T08:28:51Z

I am able to run on a local machine by adding the right slim path to PYTHONPATH. But when I am trying to run on google colab I am getting error even though I added the slim path with:

# From tensorflow/models/research/
export PYTHONPATH=$PYTHONPATH:`pwd`:`pwd`/slim

I did that but still same import error. In case of google colab I did with following command, let me know if path is not correct.
cp -R slim/ /usr/local/lib/python3.6/dist-packages/object_detection-0.1-py3.6.egg/

Problem solved when I copy nets and deployment.

Hi guys I'm having an error when I'm trying to run the training using this command:

python train.py --logtostderr --train_dir=training/ --pipeline_config_path=training/ssd_mobilenet_v1_coco.config

note:
the slim folder is already added to PYTHONPATH !!!

arascan35 · 2019-04-16T19:25:12Z

under slim folder use command 'python setup.py install' research/slim/setup.py

cj-clifton · 2019-04-19T14:39:29Z

under slim folder use command 'python setup.py install' research/slim/setup.py

This did it for me after nothing else worked, thanks!

Tourenathan-G5organisation · 2019-04-19T17:26:59Z

For google colab. Inside research folder.

import os
os.environ['PYTHONPATH'] += ':/content/models/research/:/content/models/research/slim/'

thanks you very much. This solution just came al the right time. you save my day

hoangnt2601 · 2019-05-13T02:02:42Z

I add this code sys.path.append("../../models/research/slim/") into /models/research/object_detection/models/faster_rcnn_inception_resnet_v2_feature_extrac
tor.py
It's worked for me

devimonica · 2019-06-26T04:28:08Z

@hoangnt2601 where exactly did you add the code ?

wander1985 · 2019-06-27T02:02:39Z

For windows, create a text file in your\Anaconda\environment\path\Lib\site-packages, rename it to tensorflow_model.pth, add the following two lines:
your\Anaconda\environment\path\Lib\site-packages\tensorflow\models\research
your\Anaconda\environment\path\Lib\site-packages\tensorflow\models\research\slim
Then save and close.
Do the test again. It works for me.

libichong · 2019-08-23T08:58:12Z

delete BUILD file under the folder will solve it.

anmol4210 · 2019-09-03T07:38:55Z

Hi,
I tried all the solutions but the one that worked for me was

export PYTHONPATH=$PYTHONPATH:pwd:pwd/research:pwd/research/slim

I ran the above command in the models folder...

Hope that helps someone......

rikenshah2002 · 2019-09-10T09:25:05Z

For google colab. Inside research folder.

import os
os.environ['PYTHONPATH'] += ':/content/models/research/:/content/models/research/slim/'

It worked by a small tweak:
os.environ['PYTHONPATH'] += ':/:slim/'

Thanks a Lot!
It finally worked!

luiscorujo · 2019-10-04T18:21:00Z

copy the absolute path of your slim folder (we'll call it XYZ), which is inside models/research.
then type export PYTHONPATH=$PYTHONPATH:XYZ

It really work for me. Thank you!

jsn-bln · 2019-11-07T06:21:47Z

do i need to run this everytime ? because when i run train.py the error pops up again

luiscorujo · 2019-11-07T11:48:42Z

You can run from the models/research directory exactly this:
export PYTHONPATH=$PYTHONPATH:pwd:pwd/slim
Just copy that line, just once, and it should work

Danielson23 · 2019-11-08T07:27:07Z

The correct way, if you need only object detection module:

copy object_detection and slim folder in a same location
export the working path to pythonpath using this commande (this will be done in the folder where object_detection and slim folder ar located):

export PYTHONPATH=$PYTHONPATH:pwd:pwd/slim in this folder

vatsal1301 · 2020-01-16T05:37:32Z

I slove this problem !!!!!!!!

open slim folder copy net folder and past in object _detection folder

CHAMOD · 2020-05-09T20:58:28Z

fo Windows users, you could solve this by setting PYTHONPATH as follows.
set PYTHONPATH=C:\Users...\models\research;C:\Users...\models\research\slim
then after run train.py inside object_detection dir.

dhanpalrajpurohit · 2020-05-20T09:39:56Z

Go to research/slim/ and fire this command
python setup.py build
sudo python setup.py install

i-amgeek · 2020-05-25T09:52:02Z

cd tensorflow/models/research .

Check slim exists by ls | grep 'slim'

Then run - export PYTHONPATH=$PYTHONPATH:$(pwd):$(pwd)/slim

rsrrohit · 2020-06-07T02:49:21Z

Go to research/slim/ and fire this command
python setup.py build
sudo python setup.py install

It worked for me on Google Colab!

artongdou · 2020-06-15T23:50:01Z

Go to research/slim/, delete BUILD, and run the following commands fix the 'nets' issue in windows 10 under anaconda virutal env.
python setup.py install

yegortokmakov · 2020-07-08T21:01:25Z

Changing PYTHONPATH manually doesn't seem like the right solution. Is there a reason why this repo is not using tf-slim package as a dependency and instead has a copy of the source code? Just trying to understand.

Update: There is a PR #8626 somehow related to this

Update2: Found the answer here google-research/tf-slim#6

sys.path.append(os.path.join(pwd,'models', 'research')) # point to your research dir
sys.path.append(os.path.join(pwd,'models', 'research', 'object_detection')) # point to your object_detection dir
sys.path.append(os.path.join(pwd,'models', 'research', 'slim')) # point ot your slim dir
