Calling python file in Variables section of robotframework 3.2

replace "Variables config" with "Variables /path/CLOUD234/__init__.py" in robot framework .Cloud instance is defined at run time .In each run the value changes ,so I have created a python file initpath.py as follows with fun() keyword .It will return the required path .How can I call it in Variables section of robot framework ? Thank you in advance.
import socket
import re
import os
def fun():
name = socket.gethostname()
pattern = ".*CLOUD[0-9]*"
hname = re.findall(pattern,name)
cloud_instance = hname[0].replace("-","_")
init_file = "/path/{}/__init__.py".format(cloud_instance)
return init_file

Variables section do not execute any code.
I suggest you run the python under testcase/suite up and use Set Test Variable to set the variable.

Try following: Here, you are not required to use any variables/section to call py file.
Under *** Settings *** section add
Library initpath.py

how to override downloader directory with local directory in polyglot in python

I run polyglot sentiment detection. When I upload it to the server I cannot run the downloader.download("TASK:sentiment2") command, so I downloaded the sentiment2 folder and saved it in the same folder as the python file.
I tried to set downloader.download_dir = os.path.join(os.getcwd(),'polyglot_data') pointing at the sentiment2 folder location as it says in the polyglot documentation but it doesnt work.
How do I override downloader directory so it will access the sentiment2 local folder when it executes the sentiment analysis?
Please see the full code below. This code works on my computer and localhost but returns zero when I run it on the server.
from polyglot.downloader import downloader
#downloader.download("TASK:sentiment2")
from polyglot.text import Text
downloader.download_dir = os.path.join(os.getcwd(),'polyglot_data')
def get_text_sentiment(text):
result = 0
ttext = Text(text)
for w in ttext.words:
try:
result += w.polarity
except ValueError:
pass
if result:
return result/ len(ttext.words)
else:
return 0
text = "he is feeling proud with ❤"
print(get_text_sentiment(text))
my localhost returns - 0.1666
the server returns - 0.0

after looking at the polyglot git init function. Its an env. issue. data_path = os.environ.get('POLYGLOT_DATA_PATH', data_path)
So I removed the downloader.download_dir = os.path.join(os.getcwd(),'polyglot_data')
and simply define the local POLYGLOT_DATA_PATH in the env. path.
It worked.

Flask The system cannot find the path specified: '130.127.5.9'

I've just started experimenting with flask and
I am trying to list a network driver using it. This is the command that I type on my browser. But I get an error that it cant find the path
http://127.0.0.1:5000/130.13.5.8/D/dir/
The function works for local drivers without an issue
I know why it fails. It needs 2 '\' before the actual ip or 4 '\\' .
But when I try http://127.0.0.1:5000/////130.13.5.8/D/dir/
it doesnt work.
I even tried %F%F it also doesn't seem to do the trick.
#app.route('/<path:filepath>/dir/')
def get_dir(filepath):
dir_listing = ''
for entry in os.listdir(filepath):
entry_type = 'dir' if os.path.isdir(os.path.join(filepath, entry)) else 'file'
dir_listing += '{entry_name}|{entry_type}|'.format(entry_name=entry, entry_type=entry_type)
return dir_listing

For anyone having the same issue my workaround is the following
from ipaddress import ip_address
try:
ip_address(filepath.split('/')[0])
filepath = '\\\\{filepath}'.format(filepath=filepath)
except ValueError as e:
pass

pyinstaller Error starting service: The service did not respond to the start or control request in a timely fashion

I have been searching since a couple of days for a solution without success.
We have a windows service build to copy some files from one location to another one.
So I build the code shown below with Python 3.7.
The full coding can be found on Github.
When I run the service using python all is working fine, I can install the service and also start the service.
This using commands:
Install the service:
python jis53_backup.py install
Run the service:
python jis53_backup.py start
When I now compile this code using pyinstaller with command:
pyinstaller -F --hidden-import=win32timezone jis53_backup.py
After the exe is created, I can install the service but when trying to start the service I get the error:
Error starting service: The service did not respond to the start or
control request in a timely fashion
I have gone through multiple posts on Stackoverflow and on Google related to this error however, without success. I don't have the option to install the python 3.7 programs on the PC's that would need to run this service. That's why we are trying to get a .exe build.
I have made sure to have the path updated according to the information that I found in the different questions.
Image of path definitions:
I also copied the pywintypes37.dll file.
From -> Python37\Lib\site-packages\pywin32_system32
To -> Python37\Lib\site-packages\win32
Does anyone have any other suggestions on how to get this working?

I was also facing this issue after compiling using pyinstaller. For me, the issue was that I was using the paths to configs and logs file in dynamic way, for ex:
curr_path = os.path.dirname(os.path.abspath(__file__))
configs_path = os.path.join(curr_path, 'configs', 'app_config.json')
opc_configs_path = os.path.join(curr_path, 'configs', 'opc.json')
log_file_path = os.path.join(curr_path, 'logs', 'application.log')
This was working fine when I was starting the service using python service.py install/start. But after compiling it using pyinstaller, it always gave me error of not starting in timely fashion.
To resolve this, I made all the dynamic paths to static, for ex:
configs_path = 'C:\\Program Files (x86)\\ScantechOPC\\configs\\app_config.json'
opc_configs_path = 'C:\\Program Files (x86)\\ScantechOPC\\configs\\opc.json'
debug_file = 'C:\\Program Files (x86)\\ScantechOPC\\logs\\application.log'
After compiling via pyinstaller, it is now working fine without any error. Looks like when we do dynamic path, it doesn't get the actual path to files and thus it gives error.
Hope this solves your problem too. Thanks

Error: Could not find or load main class edu.stanford.nlp.ie.crf.CRFClassifier

I tried to use StanfordSegmenter to segment a piece of Chinese but encountered the captioned problem. I first downloaded Stanford Word Segmenter version 3.5.2 from http://nlp.stanford.edu/software/segmenter.shtml
Then I wrote a python:
import os
os.environ['JAVAHOME'] = "C:/Program Files/Java/jdk1.8.0_102/bin/java.exe"
from nltk.tokenize.stanford_segmenter import StanfordSegmenter
segmenter = StanfordSegmenter(path_to_jar = "./stanford-segmenter-2015-12-09/stanford-segmenter-3.6.0.jar",
path_to_slf4j = "./stanford-segmenter-2015-12-09/slf4j-api.jar",
path_to_sihan_corpora_dict = "./stanford-segmenter-2015-12-09/data",
path_to_model = "./stanford-segmenter-2015-12-09/data/pku.gz",
path_to_dict = "./stanford-segmenter-2015-12-09/data/dict-chris6.ser.gz")
sentence = u"这是斯坦福中文分词器测试"
segmenter.segment(sentence)
But I got the following error:
Error: Could not find or load main class edu.stanford.nlp.ie.crf.CRFClassifier
Where did I make mistakes? Thanks.

I think there is some implementation error. I too had the similar problem.
To resolve the error, just try doing
segmenter._stanford_jar="./stanford-segmenter-2015-12-09/stanford-segmenter-3.6.0.jar"
If this doesn't work trying giving full path of segementer jar file on segmenter._stanford_jar
