I tried to read file that I give with absolute path.
When I run my code first that I see is this message:
D:\prog\datascience\anaconda\lib\site-packages\pydub\utils.py:170: RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work
warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)
I tried this:
PATH_TO_FFMPEG = 'D:\\prog\\ffmpeg-win-2.2.2\\ffmpeg.exe'
pydub.AudioSegment.converter = r'D:\\prog\\ffmpeg-win-2.2.2\\ffmpeg.exe'
And I separately installed ffmpeg with pip. But it didn't help.
When I try this:
raw_sound = pydub.AudioSegment.from_mp3(file=track_path)
where track_path is correct absolute path generated automatically.
So I got this this error:

can you please share the code which you are using , It will be helpful to find the exact issue.
AttributeError: 'list' object has no attribute 'read'
Also the error suggests that file is being treated as a list and not as file in the below code
stdin_data = file.read()
Hope I have given a solution.

Can I get some help debugging this, I got it down to three distinct functions with some help from my last post, now I just need to know why is this getting errors when I attempt to run it on this directory on my pc.

Your files function is a generator, to be used like an iterator. The eyed3.load function doesn't want a generator or an iterator. It wants a pathname or something like one. Passing a generator where a pathname is expected does not magically cause iteration over all the values the generator would generate. It would work better just to make a list of all the pathnames of interest and then iterate over that list, calling eyed3.load for each pathname.
I'm not trying to download the whole video, just 5 seconds of a video. I tried following this guide. However, this is for in line command and I'm trying to do this with python code. So far I've managed to extract all the required information using youtube-dl. The problem I'm having now is using ffmpeg to output the video with the given parameters, but it's saying it cannot find the file specified.
This is what I have so far:
import youtube_dl
import datetime
import ffmpeg
def getInfo():
link='https://youtu.be/nda20uSjQUI?t=11981'
ydl = youtube_dl.YoutubeDL({'outtmpl': '%(id)s%(ext)s'})
#This exctracts all the information of the link
with ydl:
result = ydl.extract_info(
link,
download=False
)
#Grabs the duration of the video
duration_info = result.get('duration')
#Grabs the url to the actual video file
url = str(result).split("'url':",1)[1].split(', ')[0]
#YouTube(link).streams.first().download('D:/Downloads')
#Determines the start time based on how the link is formatted
#They can be in three possible formats
if 't=' in link:
if link.endswith('s'):
time_seconds = link.split('t=', 1)[1].strip('s')
else:
time_seconds = link.split('t=', 1)[1]
else:
time_seconds = '0'
#Converts the time into an HH:MM:ss format
#We only want 5 seconds of video, which is what timestamp_end does
timestamp_start = str(datetime.timedelta(seconds=int(time_seconds)))
timestamp_end = str(datetime.timedelta(seconds=int(time_seconds)+5))
video_length = str(datetime.timedelta(seconds=int(duration_info)))
#If the segment we want is less than 5 seconds, such as towards the end of the video,
#then the end will be the end of the actual video
if timestamp_end > video_length:
timestamp_end = video_length
#Returns a list of [url, start, end]
return url ,timestamp_start,timestamp_end
def download_video(result):
#Checks to see if there's a valid argument
if result is None:
return 'Error: no url found'
else:
file_input = ffmpeg.input(result[0])
out = ffmpeg.concat(file_input.trim(start_frame=result[1],end_frame=result[2])).output('test1.mp4').run()
return out
download_video(result=getInfo())
And this is the error I'm getting:

I use the Pillow lib to create thumbnails. I have to create a lot of them, actually more than 10.000
The program works fine, but after processing round about 1.500, I get the following error:
Traceback (most recent call last):

My program is very straight forward:
import os, sys
import PIL
from PIL import Image
size = 235, 210
reviewedProductsList = open('products.txt', 'r')
reviewedProducts = reviewedProductsList.readlines()
t = map(lambda s: s.strip(), reviewedProducts)
print "Thumbs to create: '%s'" % len(reviewedProducts)
for infile in t:
outfile = infile
try:
im = Image.open('/Users/Marcel/images/07032017/' + infile)
im.thumbnail(size, Image.ANTIALIAS)
print "thumb created"
im.save('/Users/Marcel/product-/thumbs/' + outfile, "JPEG")
except IOError, e:
print "cannot create thumbnail for '%s'" % infile
print "error: '%s'" % e
I am performing this operation locally on my MacBook Pro.
This is to protect against a potential DoS attack on servers running Pillow caused by decompression bombs. It occurs when a decompressed image is found to have too large metadata. See http://pillow.readthedocs.io/en/4.0.x/handbook/image-file-formats.html?highlight=decompression#png
Here's the CVE report: https:// www.cvedetails.com/cve/CVE-2014-9601/
From a recent issue:
If you set ImageFile.LOAD_TRUNCATED_IMAGES to true, it will suppress
the error (but still not read the large metadata). Alternately, you can
change set the values here: https://github.com/python-pillow/Pillow/ blob/master/PIL/PngImagePlugin.py#L74
https://github.com/python-pillow/Pillow/issues/2445
following code should help you in setting what accepted answer says.
from PIL import PngImagePlugin
LARGE_ENOUGH_NUMBER = 100
PngImagePlugin.MAX_TEXT_CHUNK = LARGE_ENOUGH_NUMBER * (1024**2)
It's not documented how to set this value. I hope people find this useful.
What I am wanting to do is use the name of the current file I have that is from a generator and use the first section of the name + append .csv
The buffered stream looks like this
<_io.BufferedReader name='data/20160107W FM0.xml'>
I am having an issue with this code:
for file_to_read in roots:
print(file_to_read)
base = os.path.basename(file_to_read)
print(base)
name_to_write = os.path.splitext(file_to_read)[0]
outname = str(name_to_write[0]) + ".csv"
outdir = "output"
with open(os.path.join(outdir, outname), 'w', newline='') as csvf:
I receive this error which I believe means I am trying to split the stream rather than the name attribute of the buffered stream. Which leads me to this error.

My expected output is:
20160107W FM0.csv
for a file you are reading/writing this works:
filepath = '../data/test.txt'
with open(filepath, 'w') as file:
print(file) # -> <_io.TextIOWrapper name='../data/test.txt' mode='w' encoding='UTF-8'>
print(file.name) # -> ../data/test.txt
but the type here is <_io.TextIOWrapper name='../data/test.txt' mode='w' encoding='UTF-8'> so i am not entirely sure how you open your file or get a _io.BufferedReader.
i assume they are both derived from io.FileIO and should therefore have a .name attribute.
thanks to Ashwini Chaudhary's comment, i can recreate your exact situation:
from io import BufferedReader
filepath = '../data/test.txt'
with BufferedReader(open(filepath, 'r')) as file:
print(file) # -> <_io.BufferedReader name='../data/test.txt'>
print(file.name) # -> ../data/test.txt
I would like to save a pandas.DataFrame object into a .csv file (using DataFrame.to_csv()). To make it simple, here is the situation; my project 'Algos' contains the folder 'Plip' with a .txt file called 'plop.txt':
1,2
3,4
5,6
My script is here:
import numpy as np
import pandas as pa
# opening the file
dossier = "Plip"
fichier = "plop.txt"
fichier = open(dossier + "/" + fichier)
data = fichier.readlines()
# creating the data frame
Pair = []
Impair = []
for m in data:
impair = int(m[0:1])
pair = int(m[2:3])
Impair.append(impair)
Pair.append(pair)
M = np.array([Impair, Pair]).transpose()
Table = pa.DataFrame(M, columns = ["Impair", "Pair"])
#creating the .csv file
Table.to_csv(dossier + fichier + ".csv")
Table has been correcty created but the script returns:

I'm quite new on Python so could you be as precise as possible on your answer please ?
Thank you in advance
Seems like you reassigned fichier to a file object on L7, use a new variable instead!
