I want to use fstpso package in python which needs ANTLR3 python runtime.
I downloaded antlr_python_runtime-3.1.3.tar.gz from http://www.antlr3.org/download/Python/ and ran the command sudo python setup.py install. The output of the command was
Installed /path/to/python/packages/antlr_python_runtime-3.1.3-py2.7.egg
But after this when I try to import fstpso module in python, it throws the error
The ANTLR3 python runtime was not detected; pyfuzzy cannot import FST-PSO's FLC files
I am using python 2.7.12 on linux.
Is there something I did wrong? Or I have to update any PATH in the environment?
Thanks for your help!!
I'm fst-pso main developer. In the last days I reimplemented the Sugeno reasoner from scratch, to finally remove the pufuzzy/ANTL3 dependency. I just uploaded the new package on PyPI.
Now you can pip install the new version of fst-pso (v 1.4.0); please let me know if that works correctly.
I'm trying to create an app that uses the WebRTC VAD code.
I have found this: https://pypi.python.org/pypi/webrtcvad
The issue is that I cannot get it to work.
I extract the content into a folder but when It ry to run something it complains that _webrtcvad module is missing.
After a little research I tried to install the webRTC VAD module through pip. When doing this inside the folder I extracted into I get this:
When trying in another directory this happens:
How do I get this to work?
The problem was a bug in my webrtcvad's setup.py that caused it to use the wrong flags when compiling for Windows: it was using -DWEBRTC_POSIX instead of -DWIN32.
The fixed version has been pushed to pypi as version 2.0.9. I've confirmed that pip install webrtcvad works correctly on Windows 10.
Problem:
I'd like to install Pmw 2.0.0 (project page here) so that I can use it with tkinter in python3. The setup script from the package detects which version of python you're using and installs the version that is appropriate for your system (Ubuntu 15 in my case). I can't find any references to switches to make it install the 2.0.0 instead of 1.3.3(the Python 2.7 version), nor have I been able to get the script to install to the python3 libraries.
What I've done so far:
I've changed the python version detector in the setup script from
if sys.version_info[0]<3:
version='2.0.0' # really '1.3.3'
packages=['Pmw', 'Pmw.Pmw_1_3_3', 'Pmw.Pmw_1_3_3.lib',]
to
if sys.version_info[0]<2:
version='2.0.0' # really '1.3.3'
packages=['Pmw', 'Pmw.Pmw_1_3_3', 'Pmw.Pmw_1_3_3.lib',]
to attempt to force the installer to default to the python3 version, which it does, but it installs them in the python2.7 libraries (/usr/local/lib/python2.7/distpackages).
What I want to do:
I'm looking for a way to force the installer to put the 3.4-compatible package into the python3 libraries. If that means getting it to install both packages in their respective correct directories, that's fine, too. I'm stumped about what to try next.
Answered by RazZiel on AskUbuntu:
Link here.
Instead of using the command sudo python setup.py build and then sudo python setup.py install, I should have been using python3 to execute the setup script. I've managed to outthink myself pretty badly on this one.
I am using Ubuntu and virtualenv, and I am having this recurring problem, while attempting to use Fabric to create a deployment script. Fabric depends on paramiko, which depends on PyCrypto.
Each time I try to use Fabric, or PyCrypto directly, I get this error:
ImportError: cannot import name Random
I have tried reinstalling with pip install -U PyCrypto. I have also tried installing the python-crypto and python-crypto-dbg packages with Aptitude, to no avail. I still get the same error. Anyone have any ideas that might help me solve this problem? Thanks in advance!
It's possible that there's a file name collision in your the directory from which you're running Fabric. Do you have a file called Crypto.py in your project?
Can you get Crypto.Random to import from outside of your project directory? (but still using your virtualenv. Ipython is a big help here.)
I've had the same trouble in the past using Ubuntu. I no longer have a Ubuntu install available, but on my old 10.04 box, the file Random in the Crypto directory was missing. Make sure it exists, if it doesn't, that's the problem.
Ubuntu Maverick w/Python 2.7:
I can't figure out what to do to resolve the following import error:
>>> import ssl
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.7/ssl.py", line 60, in <module>
import _ssl # if we can't import it, let the error propagate
ImportError: No module named _ssl
UPDATE:
I recompiled the source. I was unable to figure out how to add the --with-ssl option the answers below mention, instead I got this to work by editing the lines regarding SSL in /Modules/Setup.dist.
Unrelated to the original question, but because this is the first Google result... I hit this on Google AppEngine and had to add:
libraries:
- name: ssl
version: latest
to app.yaml per: https://cloud.google.com/appengine/docs/python/sockets/ssl_support
Please NOTE: This seems to work upto Python version 2.7.9 but not for 2.7.10 or 2.7.11.
Did you build the Python from source? If so, you need the --with-ssl option while building.
Since --with-ssl is not recognized anymore I just installed the libssl-dev.
For debian based systems:
sudo apt-get install libssl-dev
For CentOS and RHEL
sudo yum install openssl-devel
To restart the make first clean up by:
make clean
Then start again and execute the following commands one after the other:
./configure
make
make test
make install
For further information on OpenSSL visit the Ubuntu Help Page on OpenSSL.
If you built Python from source, this is just a matter of dependencies: since you miss OpenSSL lib installed, python silently fails installing the _ssl module. You can see it in the final report of the make command:
Python build finished, but the necessary bits to build these modules were not found:
_bsddb _sqlite3 _ssl
_tkinter bsddb185 dbm
dl gdbm imageop
sunaudiodev
To find the necessary bits, look in setup.py in detect_modules() for the module's name.
Installing OpenSSL lib in any of the standard lib paths (/usr/lib, /usr/local/lib...) should do the trick. Anyway this is how I did :-)
I had exactly the same problem. I fixed it without rebuilding python, as follows:
Find another server with the same architecture (i386 or x86_64) and the same python version (example: 2.7.5). Yes, this is the hard part. You can try installing python from sources into another server if you can't find any server with the same python version.
In this another server, check if import ssl works. It should work.
If it works, then try to find the _ssl lilbrary as follows:
[root#myserver]# find / -iname _ssl.so
/usr/local/python27/lib/python2.7/lib-dynload/_ssl.so
Copy this file into the original server. Use the same destination folder:
/usr/local/python27/lib/python2.7/lib-dynload/
Double check owner and permissions:
[root#myserver]# chown root:root _ssl.so
[root#myserver]# chmod 755 _ssl.so
Now you should be able to import ssl.
This worked for me in a CentOS 6.3 x86_64 environment with python 2.7.3. Also I had python 2.6.6 installed, but with ssl working fine.
The underscore usually means a C module (i.e. DLL), and Python can't find it. Did you build python yourself? If so, you need to include SSL support.
I am writing this solution for those who are still facing such issue and cant find the solution.
in my case, I am using
shared hosting (Cpanel Access) Linux CentOS.
I was facing this issue
No module named '_ssl'
I tried for all possible solutions but as you know sometimes things don't work for you and in hosting you don't have access to fully root and run queries.
even my hosting provider did for me.. but NO GOOD RESULT.
so how I solved if you are using shared hosting and you have deployed your Django App using
Setup Python App
You only have to downgrade your Python Version, I downgraded from
Python 3.7.3
(As Python 3.7 does not have SSL module in it)
To
Python 3.6.8
through Setup Python App.
Hope it will be helpful for someone with the same issue,
Either install the supplementary packages for python-ssl using your package manager or
recompile Python using -with-ssl (requires OpenSSL headers/libs installed).
On Solaris 11, I had to modify setup.py to include /opt/csw/include/openssl in the SSL include search path.
