i installed python 3.7.2 still pip was not installed,for pip there must be pip.exe in folder script in directory where python is installed but in my device there nothing in it.
later i tried to install it by running get-pip.py but it throws an exception in command prompt
Command prompt throws exception :-

I'm certain that your username is the reason for this error. Python is trying to create a string of your username but the $ is causing issues. You can see this in the line ValueError: invalid variable '$'in''. Although there are other solutions, changing your username to DelSin will prevent many other headaches too.
From the code in distutils/utils.py:
def subst_vars (s, local_vars):
"""Perform shell/Perl-style variable substitution on 'string'. Every
occurrence of '$' followed by a name is considered a variable, and
variable is substituted by the value found in the 'local_vars'
dictionary, or in 'os.environ' if it's not in 'local_vars'.
'os.environ' is first checked/augmented to guarantee that it contains
certain values: see 'check_environ()'. Raise ValueError for any
variables not found in either 'local_vars' or 'os.environ'.
"""
This is utilizing the utility that's quite common in bash/Perl scripting, where you can substitute in a value using $:
SOMEPATH='$HOME/somefolder'
echo($SOMEPATH)
# '/path/to/somefolder'
Your username, unfortunately, mimics this and will cause problems until it is changed

So I'm following sentdex's object detection tutorial and I have gotten to the step where you are supposed to export the inference graph. I'm using the "export_inference_graph.py" script from Tensorflow's object_detection folder.
The problem is that I'm getting this ValueError:

I'm guessing that it has something to do with protobuf, but I've reinstalled it several times already with no success.
All help appreciated
Happened to me too. Didn't happen few weeks ago.
Until the bug is fixed, you could use an earlier version that still works.
replace line 72 in 'object_detection/exporter.py':
layout_optimizer=rewriter_config_pb2.RewriterConfig.ON)
with the old and working line:
optimize_tensor_layout=True)
I used:
rewrite_options = rewriter_config_pb2.RewriterConfig(optimize_tensor_layout=True)
but kept running into the same issue UNTIL I went and reran
python setup.py install
from my "research" folder. Then I was able to get everything to work.
Remove optimize_tensor_layout=rewriter_config_pb2.RewriterConfig.ON
change the line 71 in exporter.py
rewrite_options = rewriter_config_pb2.RewriterConfig(optimize_tensor_layout=rewriter_config_pb2.RewriterConfig.ON)
to:
rewrite_options = rewriter_config_pb2.RewriterConfig()

AFAIK this is auto-generated.
sync_chromium.py was removed back in December, replaced by a more efficient and far smaller download package. I suggest you follow the instructions at https://webrtc.org/native-code/development and get a newer checkout. It should be less likely to have download problems.
The issue here is the version of Python used. As you can see in command error prompt, the version that I have used is not 2.7+ as recomended in chromium website. Doing the change from Python to Python2.7 solve the issue.

If anyone could point me in the right direction that would be great.

Problem resolved.
I found the following support request on SourceForge which refers to a need to use short format (8.3) path and filenames in pychecker.bat and not long format as is allowed in newer versions of Windows.

I'm working with Django 1.9 in Microsoft Visual Studio. Also I'm using a virtual env, where all the needed python packages are installed. When I try to compile messages in order to add translation function to the site, the following error is raised:
ValueError: plural forms expression could be dangerous

raise ValueError, 'plural forms expression could be dangerous'
ValueError: plural forms expression could be dangerous
I've read about that (plural forms expression could be dangerous and Django: gettext raises ValueError: 'plural forms expression could be dangerous'), but the only solution I found is to remove lines referred to plural translations, for example:
"Plural-Forms: nplurals=2; plural=(n != 1);\n"
If I remove those lines in my translations files, it still raises the same error, because it takes into account other files located at the virtual env.
Update 2: If I run the server from the command line, using
python manage.py runserver
there's no problem, everything is going right. However, when I run the project from Visual Studio, the error is raised.
Is there any way to solve this problem?
Thanks in advance.
I am fairly new to Ansible and to configuration management tools in general. I've been playing around with it for the last two days and for the life of me I can't get past typing out ansible testserver. It comes back with an error message that says Unexpected Exception: No escaped character. The full error message is:

I had the same issue and changing my host file to have only one line fixed the problem.
