When I did a code to convert PDF files to JPG images, but I have met an issue.Sometimes the .pdf file work well.But sometimes there is an error,the first temp file can't read.I checked the temp folder.When it works well, all the created temp file be deleted successfully. And when the error happens,only the first temp file is deleted. I can't resolve it.Anyone can fix?
code:
from wand.image import Image
with open("C:\software\1234.pdf",'rb') as f:
image_binary = f.read()
f.close()
with Image(blob=image_binary,resolution=400) as img:

Generally when I get that problem am gonna change \ symbols to \ \ symbols and generally its solved. Try it.
I had this problem in Visual Studio Code.
table = pd.read_excel('Sales.xlsx')
When running the program on Pycharm, there were no errors.
When trying to run the same program in Visual Studio Code, it showed an error, without any changes.
To fix it, I had to address the file with //. Ex:
table = pd.read_excel('C:\\Users\\paste\\Desktop\\archives\\Sales.xlsx')
I am using Pycharm and after reviewing the Post and replies, I was able to get this resolved (thanks very much). I didn't need to specify a worksheet, as there is only one sheet on the Excel file I am reading.
I had to add the r (raw string), and I also removed the drive specification c:
data = pd.read_excel(r'\folder\subfolder\filename.xlsx')
I upgraded my python version from 3.8 to 3.9. I was using autocomplete-Pythonn extension. And an error came in my atom editor. That grammer3.9.txt not found.
Looks like this error originated from Jedi. Please do not report such issues in autocomplete-python issue tracker. Report them directly to Jedi. Turn off outputProviderErrors setting to hide such errors in future. Traceback output:

I came up with this error last time. But then I Just renamed the file grammer3.7 to grammer3.8. But I do not think this is the right way to do so.

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
