Getting filenotfound error when trying to open a h5 file

I have a h5 file that contains the "catvnoncat" dataset. when I try to run the following code, I get an error which I will include at the bottom. I have tried getting the dataset from three different sources to exclude to possibility of a corrupted file.
What I would like to know is what is causing the problem?
# My Code
import h5py
train_dataset = h5py.File('train_catvnoncat.h5', "r")
# The Error

Your code is looking in the current directory which is not where the file is.
Based on the error message, it looks like you are on windows. Is the file 'train_catvnoncat.h5' in your Downloads folder? Find that file on your system and copy the full path. You can then update this:
train_dataset = h5py.File('train_catvnoncat.h5', "r")
to something that contains the full path. Similar to this:
train_dataset = h5py.File('C:/Users/Moshen/Downloads/train_catvnoncat.h5', "r")
Pay attention to the slashes and make sure you update the file path to the actual value.

PermissionError: [Errno 13] Permission denied: Python

I have a script that is called from DJango, but it doesn't execute instead it gives PermissionError: [Errno 13] Permission denied. I'm using CMD on Windows as admin.
Here is how I'm calling:
cmd = os.path.join(os.getcwd(), "D:/commerceTest/cs50-commerceM/Photo/GFPGAN/inference_gfpgan.py --upscale 2 --model_path D:/commerceTest/cs50-commerceM/Photo/GFPGAN/experiments/pretrained_models/ --test_path inputs/whole_imgs/GFPGANCleanv1-NoCE-C2.pth --save_root D:/commerceTest/cs50-commerceM/Photo/GFPGAN/results")
#os.system("python D:/commerceTest/cs50-commerceM/Photo/GFPGAN/inference_gfpgan.py --upscale 2 --model_path D:/commerceTest/cs50-commerceM/Photo/GFPGAN/experiments/pretrained_models/ --test_path inputs/whole_imgs/GFPGANCleanv1-NoCE-C2.pth --save_root D:/commerceTest/cs50-commerceM/Photo/GFPGAN/results")
os.system('{} {}'.format('python', cmd))
Here is the message I received:

I can only guess here but the error that you are getting is because Python is trying to open a directory as a file (which won't work).
It looks like the path that you are passing in to --model_path is a directory but torch.load() expects a file, that would explain it.
I would start with understanding what exactly the script inference_gfpgan.py does and how it works.

cannot write file with full path in Python

I am using Pandas on Mac, to read and write a CSV file, and the weird thing is when using full path, it has error and when using just a file name, it works. I post my code which works and which not works in my comments below, and also detailed error messages. Anyone have any good ideas?
sourceDf = pd.read_csv(path_to_csv)
sourceDf['nameFull'] = sourceDf['nameFirst'] + ' ' + sourceDf['nameLast']
sourceDf.to_csv('newMaster.csv') # working
sourceDf.to_csv('~/Downloads/newMaster.csv') # not working

thanks in advance,

Try using os.path.join().
import os
(...)
output_filename = 'newMaster.csv'
output_path = os.path.join('Downloads', output_filename)
(...)
sourceDf.to_csv(output_path)
Use the same methodology to point pandas.read_csv() in the right direction.

You didn't specify python version.
On 3.4 you can use pathlib, otherwise use os.path.join() or quoting:
sourceDf.to_csv(r'~/Downloads/newMaster.csv')
Notice the r.
The problem is that /n is newline, which is not allowed in a path.

I am getting this error message in python while trying to open an excel sheet.....How can i solve this ?

Either make sure Book1.xls is in "C:\my_python\", which is also where your script is, or use the full path to where Bool1.xls is located. For example:
book = open_workbook('C:\\Users\\Jeeva\\Documents\\Book1.xls',on_demand=True)
