I have been getting this error anytime i run my project with (runserver_plus --cert-file cert.crt)...I already installed the django extensions and pyOpenSSL
I tried running without the (--cert-file cert.crt), that one seems to work fine buh doesnt provide me with what I am looking for .
You can try to downgrade the cryptography lib:
pip install --force-reinstall "cryptography==38.0.4"
Seems to be a temporary bug, fixed, but pending to release: https://github.com/aws/aws-sam-cli/issues/4527#issuecomment-1368871248

I had to install new package on my project to handle with Base64 images from my API, so i installed django-extra-fields, so far so good, i have made my testes locally, everything working just fine, when i pushed my changes to production and installed the new package running pip install django-extra-fields with right virtualenv on, i just keep getting the error ImportError at /
No module named drf_extra_fields.fields
That seens a silly mistake, so i checked my code like 100 times so far, and everything is right
I'm using Django 1.11 with Python 2.7
My vm is called: vm-prod_cfr_nuvem
When i run pip freeze show all my packages:
(vm-prod_cfr_nuvem) [~ site-packages]$ pip freeze
Django==1.11.6
django-cors-headers==2.1.0
django-extra-fields==2.0.2
django-filter==1.1.0
And if i enter in vm site-packages path, i can see that is installed there
/home/daniloitj/.virtualenvs/vm-prod_cfr_nuvem/lib/python2.7/site-packages
django_cors_headers-2.1.0.dist-info
django_extra_fields-2.0.2.dist-info
django_filter-1.1.0.dist-info
on my view where the show the error, as you can see, is the same path as the last one in list

Obs.: I thought that somehow my server is not using my VM or something like it... so i activate it manually on my terminal and run python manage.py shell and tried to import the lib import drf_extra_fields im still getting the same error
Obs2.: Didnt found anyone with same problem using that lib, and there is no issues about it, so probabily is my misconfiguration rather than something broke in the lib
Package Page: https://github.com/Hipo/drf-extra-fields
That error make me crazy... i solved it going back 1 small version... so instead of using 2.0.2 i'm using 2.0.1, the odd thing is... the 2.0.2 still working on my local environment, but dont work on production, and dont seems be environment problem cuz my server match all requirements to use that lib
The error:
My packages:
The error message says that I don't have this model. However I could successfully install it using pip and pip freeze shows it.
What is wrong with my install/script?
The version of Markupsafe is problematic.
I downgraded to Markupsafe==1.1.1 (because I had 2.0.1) and I don't have the problem anymore.
The module is called markupsafe._compat. See it at
https://github.com/pallets/markupsafe/tree/master/markupsafe in file _compat.py. You have a problem in your code, probably copy/paste error.
I solved the problem. Reinstalling Jinja helped
Hello everyone,
I have installed Openmdao, pyOpt and pyoptsparse on my computer. As my program works with the Scipy optimizer, I tried it with a random optimizer of pyoptsparse (that was 'ALPSO'). It worked and I was happy. But it turns out it seems to be the only one working.
Every time I try to use another one (like 'SLSQP', which is the default optimizer !), i get this message "pyOptSparse Error : There was an error importing the compiled SLSQP module", inside a frame made of '-' and '+'.
Does anybody know what to do ? I am using Ubuntu if it changes something.
Thanks to swryan for the link, i found the answer.
One of the possible answer was to put libgfortran.so.3 in anaconda2/lib, but i already had it.
They were also saying the problem was solved when installing anaconda 4.0+ but i also had the latest version.
What worked for me was to run : conda update libgfortran --force
Doing it without the --force retrogrades the scipy, which seems to disable scipy.optimize.least_squares. If you did that, you can then run conda update scipy --force
Did you get any errors when you ran 'python setup.py install' for pyoptsparse? I looked at the setup.py file for pyoptsparse and there are some instructions in there that you could try:
print("\nTo install, run: python setup.py install --user\n\n"
"To build, run: python setup.py build_ext --inplace\n\n"
"For help on C-compiler options run: python setup.py build --help-compiler\n\n"
"For help on Fortran-compiler options run: python setup.py build --help-fcompiler\n\n"
"To specify a Fortran compiler to use run: python setup.py install --user --fcompiler=<fcompiler name>\n\n"
"For further help run: python setup.py build --help"

Hello I am trying to use Point Cloud Library in Python and as I am new to this C++ library and Python I am following the tutorial on http://strawlab.github.io/python-pcl/#pcl.PointCloud
However whenever I try to import pcl and define a module such as pcl.PointCloud() I get the following error;
AttributeError: 'module' object has no attribute 'PointCloud'
I have used sys.path.append to point to the correct directory where the PCL files have been installed as they are not in site packages. It says on the above link that the C++ code has already got Python bindings but I am unsure exactly what files I am trying to call in Python. Does anybody know how to overcome this error and load these modules?
Thanks,
Andrew
Try this,
sudo add-apt-repository ppa:sweptlaser/python3-pcl
sudo apt update
sudo apt install python3-pcl
After you've done that then you should be able to run:
python3 -c 'import pcl'
and it will return with no error (as opposed to ModuleNotFoundError: No module named 'pcl').
Tested on:
Ubuntu 18.04 LTS
Python 3.6.9
Reference: https://askubuntu.com/a/1170661/922137
Try skipping the parentheses:
from pcl import PointCloud
And then create an instance of PointCloud, for example, p:
p = PointCloud()
Hope it helps!
Looks like you need PCL 1.5.1 and cython 0.16 according to this page: http://strawlab.github.io/python-pcl/

I need to install ocropus on Ubuntu 11.04.
I went through a long and painful process of trying ocropus 0.3 and 0.4 from the project's Downloads page, but to no avail - I could find no way of making it locate tesseract, which it recommended. I labored on Google and came across the page http://code.google.com/p/ocropus/wiki/InstallTranscript.
Great. Except when I issue the command:
hg clone $release https://ocropus.googlecode.com/hg/ ocropus
I get the error message:
abort: unknown revision 'ocropus-0.4.4'!
A post here http://aur.archlinux.org/packages.php?ID=13444 by the maintainer of the ocropus package for archlinux says
they have completely refactored ocropus and at the same time they have also completely removed the old repository so it's not possible to access the old "stable" versions. I suggest using the ocropus-hg package, at least for the time being.
I thought I would go ahead with this idea and issued the command:
hg clone https://ocropus.googlecode.com/hg/ ocropus #I deftly avoid any
mention of the release
The result is I get a folder with a file interestingly named ocroinst. I run it and it says I need to run the following commands:
sudo ./ocroinst packages #checks the dependencies
./ocroinst install #installs ocropus
sudo ./ocroinst dl #downloads models
I was glad and I issued the first command, which is when I got the message:
Package libjpeg8-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package libjpeg8-dev has no installation candidate
I think a certain Murphy may have had a point.
The situation, with an delicious added complication, is this:
(please correct me if I am wrong)
Ubuntu 11.04 comes with libjpeg62-dev. The required version for ocropus is libjpeg8-dev.
Ocropus requires libtiff4-dev, and libtiff4-dev depends on libjpeg62-dev. Therefore there is no way for me to uninstall libjpeg62-dev.
libjpeg62-dev conflicts with libjpeg8-dev. Therefore, I can have only one of libjpeg8-dev or libjpeg62-dev, and never both.
If libjpeg8-dev is installed, I will have no libjpeg62-dev, which means I must remove libtiff4-dev and therefore have no way to install ocropus.
If libjpeg62-dev is installed, I will have no libjpeg8-dev and thus I will have no way to install ocropus.
NOTE:
(An experiment description)
I had libjpeg62-dev installed on the system already. I figured I could take a chance and I went right ahead and changed every libjpeg8-dev I could find to libjpeg-dev, and ran the 3 commands.
It installed. No error.
This gave me great joy
until
I ran the command
ocropus <image-file-name>
and I was greeted by the charming:
ImportError: /usr/local/lib/python2.6/dist-packages/_iulib.so: undefined symbol: _ZN5iulib6dcloseEv
The more sophisticated
ocropus book2pages out image*
failed with the same error. A post on stack overflow indicates that this is caused by incorrectly versioned libraries.
THE QUESTION:
How should I proceed?
Thanks in advance.
