I installed camelot from conda-forge
using the command below.
conda install -c conda-forge camelot-py

I googled the error above and found this issue. However, I am unable to solve this issue as I am not able to find out what I need to do with the file named libglib.

Doing this worked for me:
pip install opencv-python

Your anaconda environment is broken in some way.
As a first step make sure you've installed the correct version for your platform (I guess Mac OS X). Once done, set LD_DEBUG environment variable to libs + files, start your python command again and make sure it picks native libraries from inside anaconda package and not somewhere else.

Python Cryptography Error cannot import name certificate_transparency

trying to run a pymodbus tcp server and im getting this stack trace... at a total loss here so any help is appreciated. Thanks!

I was using pip 7 and got the same problem. Upgrading to pip 9 solved it. I'm not sure about the cause.

I've been hitting this while attempting to update Python Cryptography for Solaris 11.4, using the https://github.com/oracle/solaris-userland/ build system. A "simple" update to pip isn't an option for me, that's not how we do things.
I eventually figured out the solution: I'd built the package incorrectly.
Cryptography 2.1.4 depends on cffi > 1.7. Both of these packages have new deliverable bits compared to the versions we were shipping.
Failing to update the package manifest to correctly track the new files results in both cffi and cryptography being unable to import symbols that the current versions depend upon.
[A very big thankyou to Alex Gaynor in #cryptography-dev who set me on the right path to figuring this out].

If you build cryptography and look at what it delivers, you will find that there is in fact a file (shipped on Solaris as /usr/lib/python-$(PYVER)/vendor-packages/cryptography/x509/certificate_transparency.py) - and if that file isn't in the rest of the hierarchy then you end up with exactly this ImportError.

it works for me (problems with paramiko):

pip install --process-dependency-links ctutlz

I had a similar issue on RHEL 6.7 x86_64 running Python 2.7.8 with an old version of pip (1.4.1)
It was because I had been installing the "cp27m" builds rather than "cp27mu" builds.
With the old pip 1.4.1 build, it did not complain installing the cp27m builds.
Whereas when upgrading pip to 9.0.3, it spat out the true error ...
(bmcs2)bash-4.1$ pip install cffi-1.11.5-cp27-cp27m-manylinux1_x86_64.whl
cffi-1.11.5-cp27-cp27m-manylinux1_x86_64.whl is not a supported wheel on this platform.
(bmcs2)bash-4.1$ pip install cryptography-2.1.3-cp27-cp27m-manylinux1_x86_64.whl
cryptography-2.1.3-cp27-cp27m-manylinux1_x86_64.whl is not a supported wheel on this platform.
The "ImportError: cannot import name certificate_transparency" was resolved using the "cp27mu" builds. When using the "cp27mu" build, both the pip 1.4.1 and pip 9.0.3 versions worked fine.
cffi-1.11.5-cp27-cp27m-manylinux1_x86_64.whl versus cffi-1.11.5-cp27-cp27mu-manylinux1_x86_64.whl

I think this more like a paramiko issue not pip. Upgrading pip didn't solve this in my environment i had to downgrade my paramiko version to a version that does not have a libffi dependency, this worked for me:
pip2.7 install paramiko==1.17.0
this issue is related to: https://github.com/paramiko/paramiko/issues/1401

I got this error while trying to run Scrapy in AWS Lambda, deploying with a zip file.
I followed the instructions in https://www.perrygeo.com/running-python-with-compiled-code-on-aws-lambda.html, which basically instructs you to start an Amazon Linux EC2 instance, install the requirements and build the zip from it.
After setting up the whole thing, the first package I created still gave me the same error, but I realised that was because a hidden folder, .libs_cffi_backend, was missing from the zip file. That folder contains a .so file that if not present causes ImportError. After forcefully including it, it worked.

Error installing mpi4py

Failed to start python after installing speech_recognition package

I've already installed this package (SpeechRecognition) on my laptop, now I'm trying to make it work on my Imac (sierra aswell).
I followed the installation the same as on the macbook.
But when trying to run the test I get following error.
python -m speech_recognition

Try going to terminal and typing in that:
python -m speech_recognition
or
python3 -m speech_recognition
If that's what your running.
it depends what version of python your using, Sierra comes with python IDLE 2.7.10 already installed.
if you download those modules for python it will download them to work with 2.7.10 not the 3.0 + you might be using.
so if you downloaded python3 and are trying to run it with python3 it won't work, only from 2.7.10 so try typing in.
python -m speech_recognition
Like i suggested and see if it works in the terminal, if it does then it means i was right and python 2.7.10 will work with it.
