tried to run docly to auto generate some comments for my python code. installation went smooth:
pip install -U PyYAML
pip install docly
however, when trying to process the first file via:
docly-gen first_file.py
there keeps coming the error

Issue while installing pip python

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

Error exporting inference graph (ValueError)

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()

Python code runs in interactive prompt but not as script

I am trying to interface with an Ocean optics spectrometer using seabreeze (seabreeze) and pyseabreeze (pyseabreeze).
If I enter python from the command prompt (cmd) in windows and enter the following code line by line, it works. However, if I put it in a script (spec_test.py) and try running it from cmd.exe by using 'python spec_test.py', it will not work.
I have searched around a lot for similar problems but none seem to cover the issue I'm having. I am running Windows 7 64 bit, python 3.5.2 installed using anaconda. I also had to install pyusb and libusb to use pyseabreeze.
The code:
import seabreeze
seabreeze.use('pyseabreeze')
import seabreeze.spectrometers as sb
devs = sb.list_devices()
print(devs)
spec = sb.Spectrometer(devs[0])
print(spec.model)
and the error message I get:

Thanks for any help!
Edit:
For some reason I figured this out, thought it might help describe the issue. If I enter interactive python from cmd.exe and paste the code instead of typing it in manually, I get the same error. This makes me think (most likely I'm wrong) that it is somehow tied up with speed of imports. I tried adding a sleep for a few seconds in between lines 3 and 5, to simulate what happens when I am typing in the prompt, but that didn't help. I hope this was descriptive enough.

Your initial guess was not far off. I had exactly the same problem, however, on Windows 7 32bit with Python 2.7. The example code gchaks linked to was running fine.
When I tried executing the script several times in quick succession, the error message changed and pointed at a empty devices list. I added a delay of 2 seconds after
devs = sb.list_devices()
and that solved the problem. Your code was running just fine on a Linux machine btw.
Another hint: If your code should run once, but then you run into another error message, make sure you close the device connection or dis- and reconnect the spectrometer.

help('modules') crashing? Not sure how to fix

I was trying to install a module for opencv and added an opencv.pth file to the folder beyond my sites.py file. I have since deleted it and no change.
When I try to run help('modules'), I get the following error:
Please wait a moment while I gather a

What gives?!

This happens because help('modules') imports all modules, which can result in a lot of unsentineled code being executed. There's nothing you can do short of reporting bugs in every single package that causes this (opencv in this case) and wait for them to fix it.
