Expected bytes, HTTPResponse found

I want to use linebot to make an object detection application, and when I retrieve the url which is a http type, the system called an error.

I do not have ideas which part of the code below requires a byte type file to make a detection(the PIL module?).
Is it necessary to change to the byte type, when it comes to an object detection?

Open PIL image from zip (Kaggle competition)

I am trying to read an image from kaggle competition (It is an old competition, but I would like to practice):
https://www.kaggle.com/competitions/dogs-vs-cats-redux-kernels-edition
I am trying to read images from the training file zip using this code:
def get_files_names(zip_file_path):
with ZipFile(zip_file_path) as myzip:
return myzip.namelist()
def get_image(zip_path, image_name):
with ZipFile(zip_path) as myzip:
# print(myzip.namelist()[:10])
with myzip.open(image_name) as myfile:
# img = Image.open(myfile)
img = Image.open(myfile)
return img
names = get_files_names(train_file_path)
img = get_image(train_file_path, names[1])
img.show()
I am getting this error:

If I extract the file into finder (using mac), then I see this image:

What am I doing wrong?

Autokey: sporadic error on system.exec_command

I have a script that grabs the window title and writes out a debug statement based on whether the file title includes a certain string.
active_title = window.get_active_title()
counter = system.exec_command("date '+%s'")
newcounter = counter[-5:]
counter = newcounter
time.sleep(.4)
if '.php' in active_title:
output = "die('<pre>[" + str(counter) + "] ' . date('Y-m-d H:i:s'));"
time.sleep(.2)
clipboard.fill_clipboard(output)
time.sleep(.2)
keyboard.send_keys('<ctrl>+v')
if '.js' in active_title:
output = "console.log('[" + str(counter) + "] ' + Date.now())"
time.sleep(.2)
clipboard.fill_clipboard(output)
time.sleep(.2)
keyboard.send_keys('<ctrl>+v')
time.sleep(.2)
keyboard.send_keys("<ctrl>+s")
99% of the time it works without issue, but that 100th time it throws this error:

RuntimeError: Request reply to unknown request. Can't happen!
Closing and restarting Autokey helps, but I'd like to avoid the error if at all possible. I have several scripts that get the window title, and this is the only script that has this issue. Is there something wrong with using system.exec_command?

Since you are invoking the clipboard, it helps to add to the start and the end
os.system("sleep .1; xsel -cb")
to clear it.

Solving IOError while generating a pdf using reportlab and generated qr code image

I am trying to generate a qr code from text, and then insert into a reportlab pdf.
My code:
def qr_code_as_image(text):
from io import BytesIO
print("In show_qr")
img = generate_qr_code(text)
print(img, type(img))
i = Image(img)
print(i, type(i))
return i

line2 = ("MRD No.", self.linkedcustomer.cstid,
"Date", self.prescription_time)
line3 = ("No.", "#", "Doctor", self.doc.name)
datatb = [line1, line2, line3]
patientdetailstable = Table(datatb)
patientdetailstable.setStyle(self.patientdetails_style)
col1 = patientdetailstable
checkin_url = reverse('clinicemr', args=[self.checkin.checkinno])
qr_image = qr_code_as_image(checkin_url)
qr_image.hAlign = 'LEFT'
col2 = Table([[qr_image]])
tblrow1 = Table([[col1, col2]], colWidths=None)
tblrow1.setStyle(self.table_left_top_align)
self.elements.append(tblrow1)

from django.http import FileResponse, Http404
from functools import partial
# use the temp file
cmd = "cat " + str(temp.name)
print(os.system(cmd))
print(footer_content, type(footer_content))
doc = SimpleDocTemplate(
temp.name,
pagesize=A4,

doc.build(self.elements,

From the error, it appears that it is erroring out on getting the name of the image file. But there is no file. The image is being generated from BytesIO.

Your generate_qr_code function, which you did not show us, is NOT returning a BytesIO object. It's returning the raw bytes of the PNG image. When you print(img, type(img)), it told you it was of type "bytes", right? That's a string of bytes, not a BytesIO object. If you wrap those bytes into a BytesIO object, then the reportlab Image constructor will be able to handle it.
