I tried to convert a batch of .svgz into a single pdf file following the instructions of Generating PDFs from SVG input.
from svglib.svglib import svg2rlg
from reportlab.graphics import renderPDF
renderPDF.drawToFile(svg2rlg("images/p1.svgz"), "out.pdf")
Encounter the issue OSError: Not a gzipped file (b'<s'). The file is not compressed at all as I can read the file with cat.
I changed the filename extension to .svg with mv, run again the above codes renderPDF.drawToFile(svg2rlg("images_svg/p1.svg"), "out.pdf"), but got nothing response.
I terminated the process with Ctrl + c, and got this,
$ python3 img_to_pdf.py

I use pyquil for azure quantum, and submit jobs with run_batch method of AzureQuantumComputer class. For batches with up to 10 circuits there are no problems, but larger batches result in an error below.

I tried to run different circuits, it seems to only depend on the number of circuits in a batch, not the structure of a circuit. Programs are compiled to native quil locally.
While the epub is being generated successfully, but when I try to read the epub using readers like Calibre or Sigil. They throw errors like certain files are missing.
Here's my code to generate the epub file:
book = epub.EpubBook()
book.set_title(novelName)
book.set_language("en")
book.set_cover('temp.jpg', content=open('temp.jpg','rb').read())
book.set_identifier("test")
for i in authorNames:
book.add_author(i)
for i in range(1):
driver.get(chapterLinks[i])
try:
content=driver.find_element_by_id('chr-content').get_attribute("innerHTML")
time.sleep(5)
except Exception as e:
driver.close()
driver = webdriver.Chrome(ChromeDriverManager().install(),options=options)
driver.get(chapterLinks[i])
content=driver.find_element_by_id('chr-content').get_attribute("innerHTML")
time.sleep(5)
soup = BeautifulSoup(content)
ads=soup.find("div", class_="ads-holder")
if(ads!=None):
ads.decompose()
print(chapterNames[i], chapterLinks[i])
chapterName=chapterNames[i].replace("-","")
c=epub.EpubHtml(title=chapterName,
file_name='{}.xhtml'.format(chapterName),
lang='en')
c.set_content(str(soup).encode('utf-8'))
book.add_item(c)
chapterList.append(c)
book.toc = chapterList
book.spine = chapterList
book.add_item(epub.EpubNcx())
book.add_item(epub.EpubNav())
epub.write_epub('test.epub', book)
and here are the errors:

When the pc is connected to the internet the program runs correctly and prints "Cool, thank you for connecting me to the internet" But when I run the program without the internet an error occurs with the note: During handling of the above exception, another exception occurred.

TypeError: catching classes that do not inherit from BaseException is not allowed
Your error means that you're trying to catch an object that isn't an exception (i.e. a class that isn't an instance of BaseException). Only exceptions are allowed to be caught, because only exceptions can be raised.
According to the docs the method urllib.request.urlopen raises the exception URLError if something goes wrong, so catch that in order to react to an error.
Example implementation:
try:
urllib.request.urllopen("foo.com")
except urllib.error.URLError as e:
print("Couldn't open foo.com. Error:")
print(e)
I am trying to parallelize the tasks of correcting texts on many documents with Python, so I naturally found "joblib". I want each task to be to correct a given document. Here is the structure of the code:
if __name__ == '__main__':
lexicon = build_compact_lexicon()
from joblib import Parallel, delayed
import multiprocessing
num_cores = multiprocessing.cpu_count()
results = Parallel(n_jobs=num_cores)(delayed(find_errors)('GDL', i, 1, lexicon) for i in range(1798, 1820))
I am using the function find_errors summed up here :
def find_errors(newspaper, year, month, lexicon):
# parse the input newspaper text data using etree parser from LXML
# detect errors in the text
return found_errors_type1, found_errors_type2, found_errors_type3
This does raise me a few errors

I don't understand if this is due do something related with configs or if my function doesn't fit in a parallel implementation... (I guess it should...)
Did it happen to some of you before?
Hope my question is clear and there is enough information for someone to give me some help!
The addresses I am trying to open look like this:
"//usa-qa/QAEngr/QA_Team_VSripathi/Negar/Help files/broken/header_test/main.htm"
They are located on a company's internal network.
I tried this piece of code:
import urllib
import urllib.request as ur
address="//usa-qa/QAEngr/QA_Team_VSripathi/Negar/Help files/broken/header_test/main.htm"
info=ur.urlopen(address)
which results in the following error:

It is interesting that this problem gets solved when I map the network drive on my computer which runs windows 8: (http://windows.microsoft.com/en-us/windows-8/create-shortcut-to-map-network-drive)
Also the file can be opened with the open function instead of the urlopen, however I prefer to use urlopen since for my purpose the address might be a website's url.
