Hi I got the same error. have you find the solution? |
|
Me too, any ideas for this? |
|
I have also got the same problem. Anybody found a solution? |
|
This is how I solved it. |
|
@Drgx96 ，Hi emmmmm,I just did as what you said ,but then I got another warnning , The backend was originally set to 'module://ipykernel.pylab.backend_inline' by the following code: if name == 'main': |
|
so have u found? cause i also tried that and got the same error like ur CallMe smth like' line for line in traceback.format_stack() |
|
I also have this problem. Did you fix it and how? |
commit:7a9934d has change the matplotlib imports, it cause object_det4ection_tutorial.ipynb to unable to run. This commit fixes the problem.
|
I clone the lastest tensorflow/model, still have this problem. |
|
I too fixed it by just commenting import matplotlib matplotlib.use('Agg') # pylint: disable=multiple-statements in visualization_utils.py file and by removing (matplotlib line -> from matplotlib import pyplot as plt) from bottom and placing it in the beginning of py file (object detection_tutorial.py) |
|
@majeedhussain49 Can you elaborate that fix. Please mail it to savantadarsh@gmail.com |
|
-cd tensorflow/models/research/object_detection/utils/ |
|
In latest API version, it has been like you say @tibro26 : Still not work. |
|
I have a workaround for this issue. Just put the following code directly in the Python file that you're trying to run: import matplotlib; matplotlib.use('Agg')For instance I was trying to use model_main.py, so I changed the import section just below the from __future__ import absolute_import
from __future__ import division
from __future__ import print_function
import matplotlib; matplotlib.use('Agg')
from absl import flags
import tensorflow as tf
from object_detection import model_hparams
from object_detection import model_lib
.....This also fixed the following Tkinter threading exception: |
|
I don't think this is a fatal warning. My Program runs fine even with this warning. I,m using tensorflow 1.9 on python2 |
I got the same warning from the commit of 17fa528$ git log -1 |
|
I just removed the line in the first block that read |
|
Closing as this is resolved |
|
I restarted the kernel that imports |
|
This warning is still present. |
|
Update matplotlib and restart kernel worked for me. |
hi ,i was following the tutorial https://pythonprogramming.net/introduction-use-tensorflow-object-detection-api-tutorial/ and i used jupyter to run the object_detection_tutorial.ipynb,but i cant get the same result as the tutorial did,iwent into the jupyter and run the command run all,but i get this when running part 3

This call to matplotlib.use() has no effect because the backend has already

The backend was originally set to 'module://ipykernel.pylab.backend_inline' by the following code:
