This is weird.Following is code sample

Trying to load a ResNet 18 pre-trained model using the torch.load(PATH) but getting Unicode decode error please help.
Traceback (most recent call last):
File "main.py", line 312, in <module>
main()
File "main.py", line 138, in main
checkpoint = torch.load(args.resume)
File "F:\InsSoft\Anaconda\lib\site-packages\torch\serialization.py", line 593, in load
return _legacy_load(opened_file, map_location, pickle_module, **pickle_load_args)
File "F:\InsSoft\Anaconda\lib\site-packages\torch\serialization.py", line 773, in _legacy_load
result = unpickler.load()
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xbe in position 2: invalid start byte
This error hits whenever the model is pretrained on torch version < 0.4 but using torch version > 0.4 for testing / resuming.
so use checkpoint = torch.load(args.resume,encoding='latin1')
I am very new to socket and communication using MQTT. Already spent hours but dont know what is wrong. Kindly help me to fix this error.
I am using the below code,
import socket
import json
from random import randint
from inference import Network
import paho.mqtt.client as mqtt
HOSTNAME = socket.gethostname()
IPADDRESS = socket.gethostbyname(HOSTNAME)
MQTT_HOST = IPADDRESS
MQTT_PORT = 1883 ### TODO: Set the Port for MQTT
MQTT_KEEPALIVE_INTERVAL = 60
client = mqtt.Client()
client.connect(MQTT_HOST,MQTT_PORT,MQTT_KEEPALIVE_INTERVAL)
And the error and traceback is shown below,

I want to crop and resize multiple images in many sub-directories. The code works if the images are in the same directory, but fails to read from other directories.
I have tried using os.walk() module. It successfully iterate the files from all subdirectories, but the pillow's Image.open() function fails to access the images and thereby displaying error: "image.." not found.
import os
from PIL import Image
for dirpath, dirnames, files in os.walk('.'):
for filename in files:
t = filename.split(".")
ext = t[-1]
if ext in ["jpg"]:
print(filename)
coords = (500, 250, 810,720)
image_obj = Image.open(filename)
cropped_image = image_obj.crop(coords)
resized_image =cropped_image.resize([227,227])
# name = "./data2" + str(i) +".jpg"
resized_image.save("new" + filename)
I expect the code to recursively crop and resize the images in all the sub-directories. The following error occurred.
frame0.jpg
Traceback (most recent call last):
File "........./data2/cropitall.py", line 18, in <module>
image_obj = Image.open(filename) #path of image to be cropped
File "C:\Python36\lib\site-packages\PIL\Image.py", line 2652, in open
fp = builtins.open(filename, "rb")
FileNotFoundError: [Errno 2] No such file or directory: 'frame0.jpg'
Process finished with exit code 1
To open the image you need the entire path to the file, not just file name.
Instead of
image_obj = Image.open(filename)
do
path = os.path.join(dirpath, filename)
image_obj = Image.open(path)
mystring = subprocess.check_output(["sudo iwlist wlan0 scan"], universal_newlines=True)

print (mystring)

what is the problem?
what is the problem?
The OSError: [Errno 2] No such file or directory refers to the subprocess command which is to be executed.
The program arguments must be passed individually in the sequence, so change
["sudo iwlist wlan0 scan"]
to
["sudo", "iwlist", "wlan0", "scan"]
It looks like your code is using a file called "subprocess" located here: /usr/lib/python2.7/subprocess.py
But the file or directory isn't there. You can change the dir or put the file in the correct folder.
If it's an packaged. Did you install the package with pip or sth? Is it imported?
I'm trying to read this pdf file (https://www.accessdata.fda.gov/cdrh_docs/pdf14/K141693.pdf) and am following these suggestions from SO
Opening pdf urls with pyPdf
I have actually downloaded the file locally and am running the following code
import PyPDF2
pdf_file = open("K141693.pdf")
pdf_read = PyPDF2.PdfFileReader(pdf_file)
but my code hangs indefinitely. I'm running Python 2.7 and here is the stacktrace.

I came across another post here PyPDF2 hangs on processing but that too doesn't have a response.
You need to parse the file in binary ('rb') mode. (This works in Python 3:)
import PyPDF2
pdf_file = open("K141693.pdf", "rb")
read_pdf = PyPDF2.PdfFileReader(pdf_file)
