AttributeError: module 'resource' has no attribute 'getpagesize' - python-3.x

Question

I am trying to use Tensorflow Object Detection API and I follow the steps mentioned in the given link -
https://tensorflow-object-detection-api-tutorial.readthedocs.io/en/latest/install.html#tf-models-install
When I try to access the Object Detection Jupyter Notebook through jupyter notebook
I am facing the below exception
Traceback (most recent call last):
File "/usr/local/bin/jupyter-notebook", line 7, in <module>
from notebook.notebookapp import main
File "/home/dinesh/.local/lib/python3.6/site-
packages/notebook/notebookapp.py", line 79, in <module>

packages/prometheus_client/process_collector.py", line 12, in <module>
_PAGESIZE = resource.getpagesize()
AttributeError: module 'resource' has no attribute 'getpagesize'
I am using
Python - 3.6.3
Jupyter - 1.0.0
How can I overcome this exception?

Answer 1

Got a similar error. My project contained modules (folders)
model
resource (replaced with resources)
service
So I changed the name of the resource module to resources (change name to any appropriate module name)

Answer 2

I have the same error ,after rename my resource module in the PYTHONPATH , it works right. check your PYTHONPATH, is there a resource module?

I had a similar issue on starting Jupyter Notebooks on Windows 10.
When I initially ran the regular startup script, I got a windows terminal that opened and immediately closed, too fast to see any error messages. So, I opened a windows 10 powershell terminal and ran
conda update conda
and
conda update --all
then I ran
jupyter-notebook at the windows prompt. The results were:
Traceback (most recent call last):
File "E:\Users\Bob\anaconda3\Scripts\jupyter-notebook-script.py", line 6, in

File "E:\Users\Bob\anaconda3\lib\site-packages\notebook\notebookapp.py", line 76, in

File "E:\Users\Bob\anaconda3\lib\site-packages\prometheus_client\process_collector.py", line 11, in
_PAGESIZE = resource.getpagesize()
AttributeError: module 'resource' has no attribute 'getpagesize'
I opened process_collector.py in the site-packages\prometheus_client in notepad++ and changed
line 9 import resource to import resources
and
line 11 _PAGESIZE = resource.getpagesize() to _PAGESIZE = resources.getpagesize()
I searched for other instances of resource and found none. I then saved the file and reran jupyter-notebook at the windows terminal prompt.
This time I got:
Traceback (most recent call last):
File "E:\Users\Bob\anaconda3\Scripts\jupyter-notebook-script.py", line 10, in
sys.exit(main())
File "E:\Users\Bob\anaconda3\lib\site-packages\jupyter_core\application.py", line 254, in launch_instance

old_soft, old_hard = resource.getrlimit(resource.RLIMIT_NOFILE)
AttributeError: module 'resource' has no attribute 'getrlimit'
Still having Notepad++ open, I opened notebookapp.py in site-packages\notebook and searched for resource. I found and changed the following lines:
Line 37 import resource to import resources
line 40 resource = None to resources = None
line 1036 resource is None to resources is None
line 1040 soft, hard = resource.getrlimit(resource.RLIMIT_NOFILE) to
soft, hard = resources.getrlimit(resources.RLIMIT_NOFILE)
line 1693 if resource is None: to if resources is None:
line 1697 old_soft, old_hard = resource.getrlimit(resource.RLIMIT_NOFILE) to old_soft, old_hard = resources.getrlimit(resources.RLIMIT_NOFILE)
line 1706 resource.setrlimit(resource.RLIMIT_NOFILE, (soft, hard)) to
resources.setrlimit(resources.RLIMIT_NOFILE, (soft, hard))
I searched for other instances of resource and found none. I then saved the notebookapp.py file and reran jupyter-notebook at the windows terminal prompt. This time Jupyter Notebooks opened with the expected files tab displayed. I quit out of Jupyter Notebooks and restarted using the normal link to the startup script and it worked as expected.
I am not sure what caused this issue. I did not intentionally update anything before I saw the issue. Yesterday, Jupyter Notebooks worked as expected, today when I tried to run it, I got the flicker screen as described above.

[Quick look for root cause]
Check if you have set PYTHONPATH in your system -
try to rename that momentarily
run "jupyter notebook"
[Fix the issue]
if the issue is resolved by doing this then
search "resource" folder within all paths mentioned in PYTHONPATH
if such folder found then rename/refactor it to other name e.g. "resources"
