I'm trying to install Open CV 2 on a shared hosting inside a virtualenv.
I already got numpy and all those stuff downloaded using Pip. I'm just having a bit of trouble with OpenCV2
I run this command in the ssh session
(penv)[dire]$ cmake -D MAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=$VIRTUAL_ENV/local/ -D PYTHON_EXECTUABLE=$PYTHONPATH/python2.7 -D PYTHON_PACKAGES_PATH=$VIRTUAL_ENV/lib/python2.7/site-packages -D INSTALL_PYTHON_EXAMPLES=ON ..
and the error I get is
Traceback (most recent call last):
File "/home/bashtroubles/website.com/public/NNPics/penv/bin/cmake", line 11, in <module>
sys.exit(cmake())

This is also my .bashrc if it matters
# ~/.bashrc: executed by bash(1) for non-login shells.
# Load pythonbrew
alias pb='pythonbrew'
export PYTHONPATH=~/.pythonbrew/pythons/Python-2.7.3/lib
[[ -s /home/bashtroubles/.pythonbrew/etc/bashrc ]] && source /home/bashtroubles/.python$
# Load custom python installation
export PATH=~/opt/python-2.7.3/bin:${PATH}
export PYTHONPATH=~/opt/python-2.7.3/lib
The specific version is opencv-2.4.13 and the python version is 2.7.3
I believe the issue is because it's using the python2.7 from
File "/usr/lib/python2.7/subprocess.py", line 1249, in _execute_child
raise child_exception
Any ideas on how to get this going without a permission denied issue?
I ran into this problem. It looks like the binary it's trying to call isn't marked as an executable. I ran this to change the permissions
sudo chmod +x -R /usr/local/lib/python2.7/dist-packages/cmake-3.13.3-py2.7-linux-x86_64.egg/cmake/data/bin

I am trying to setup a Jenkins pipeline which runs tox inside a docker container. There is a known issue that shebang lines get very long inside Jenkins, and two solutions are proposed. The first is to use --workdir to select a shorter path. This option works in principle, but I loose the automatic unique path-names per project from Jenkins. I would thus prefer to use the second option, TOX_LIMITED_SHEBANG. Unfortunately, that seems to fail with the following error when the package under test is supposed to be installed: FileNotFoundError: [Errno 2] No such file or directory: "b'/bin/sh'": "b'/bin/sh'". I have verified that /bin/sh is in fact available in the docker container. The Jenkinsfile looks as follows:
node("docker") {
// burnpanck/tox-base contains tox and many python versions
docker.image('burnpanck/tox-base').inside {
checkout scm
stage('Matrix-test using Tox') {
// verify that /bin/sh exists
sh 'ls -al /bin'
// the following does not work
sh 'TOX_LIMITED_SHEBANG=1 tox -vv'
// the following works
// sh 'tox --workdir=/var/jenkins_home/tox'
}
}
}
Tox is version 3.1.2 and runs under python 3.6 (the docker image is generated from this Dockerfile). What surprises me a little is the "b'/bin/sh'" coming from str-ing a bytes instance. Could it be that tox is in fact trying to run a program by the name sh' in the path b'/bin?
The tox.ini in use simply calls pytest:
[tox]
envlist = py36
[testenv]
recreate = True
commands =
pytest
The full backtrace from tox (Jenkins console output) is the following:
py36 create: /var/jenkins_home/workspace/_debug_jenkins-long-shebang-L7UHBNCVPSOBSTKZ7COPFJBJLWR5XZXFIAD7TBGC4WQLVDLZYVQQ/.tox/py36

We currently have an open bug for this. TOX_LIMITED_SHEBANG is broken when tox is running under python3.
The root cause is there's a .decode() missing and a list ends up with mixed bytes and str instances.
Workarounds until I fix it are to use tox with a python2 interpreter or don't use TOX_LIMITED_SHEBANG.
Trying to create a virtualenv using the command:

How oh how can I start a virtualenv using python3.2?
You need to supply the path to the path to the Python interpreter with -p, not the lib directory.
Because you're passing that directory, virtualenv is trying to execute it, and therefore you get Permission denied. So use the path to the python executable in the bin directory instead (use which python3.2 to find out if you don't know the location).
This should work, assuming your Python 3.2 interpreter can be found at /usr/local/bin/python3.2:
mkvirtualenv -p /usr/local/bin/python3.2 splinter
I am getting the following error while running gclient runhooks for building chromium.

In order to get permission of the directory "/usr/bin/python src/tools/clang/scripts" I tried chown and chmod but it returned the same error.
I think the python scripts in scripts directory are trying to modify some other files or directories .... try to trace what it is trying to do...... You have not specified the OS on which u are working ....... see this link https://github.com/aerospike/aerospike-client-python/issues/22
It says Linux Mint 17 is not supported officially.....
Actually the directory was not mounted with execution permission. So I remounted the directory with execution permission using
mount -o exec /dev/sda5 /media/usrname
and it worked fine.
Attempting to call a shell script with options from a python script.
The line ./dropbox_uploader.sh -s download /test/pictures pictures/ runs fine via SSH but errors when called from a python script:
import subprocess
subprocess.call(['./dropbox_uploader.sh -s download /test/pictures pictures/'])
Here is the error message:
Traceback (most recent call last):
File "sync.py", line 2, in <module>

raise child_exception
OSError: [Errno 2] No such file or directory
In case if the first argument of subprocess.call is a list, it must contain the executable and arguments as separate items:
subprocess.call(['./dropbox_uploader.sh', '-s',
'download', '/test/pictures', 'pictures/'])
or, maybe, more convenient:
import shlex
cmd = './dropbox_uploader.sh -s download /test/pictures pictures/'
subprocess.call(shlex.split(cmd))
There is also an option to delegate parsing and execution to the shell:
cmd = './dropbox_uploader.sh -s download /test/pictures pictures/'
subprocess.call(cmd, shell=True)
(But please note the security warning)

I understand that I was not allowed to do that, but why? python 2.7 is located there and I want to use it. Is there any way to use it in my virtualenv?
I hope that this isn't too basic of a question. I am still pretty new to Unix command line.
You have to point to the python executable, which you are not doing here. Its located at /Library/Frameworks/Python.framework/Versions/2.7/bin/python. Run this
sudo virtualenv curdir -p /Library/Frameworks/Python.framework/Versions/2.7/bin/python
