I am trying to make a python script which can convert a file from 'm4a' to a '.wav' however it is not able to find the files, returning "[WinError 2] The system cannot find the file specified" every time.
Paths[0] include the full path of the file in question
m4a_file = paths[0]
wav_filename = filename + ".wav"
#track = AudioSegment.from_file(m4a_file, format= 'm4a')
track = AudioSegment.from_file(file = relative_path,
format = 'm4a')
file_handle = track.export(wav_filename, format='wav')
// I've tried to
I've given both relative and full path for the file in question
'c:\Users\user\....\Workspace\Pollux\my_file.m4a'
and
'my_file.m4a'

I have object and attributes data in separate csv files. there are 3 different types of objects.
Directory may contain different files but I have to read and process object and attribute files. After reading the object file and then will have to read respective attribute file.
Below is code and files
plant = []
flower = []
person = []
for file_name in os.listdir(dir_path):
if os.path.isfile(os.path.join(dir_path, file_name)):
if file_name.startswith('plant_file'):
plant.append(file_name)
if file_name.startswith('person_file'):
person.append(file_name)
if file_name.startswith('flower_file'):
flower.append(file_name)
for file_name in person:
object_file_path = dir_path + file_name
attribute_file_path = dir_path + file_name.replace('file','attributes_file')
read_object_csv = pd.read_csv(object_file_path)
read_attribute_csv = pd.read_csv(attribute_file_path)
for file_name in flower:
object_file_path = dir_path + file_name
attribute_file_path = dir_path + file_name.replace('file','attributes_file')
read_object_csv = pd.read_csv(object_file_path)
read_attribute_csv = pd.read_csv(attribute_file_path)
file name contains date and time in the format YYYYMMDDHHMMSS . Sample file names are
plant_attributes_file_20221013134403.csv
plant_attributes_file_20221013142151.csv
plant_attributes_file_20221013142455.csv
plant_file_20221013134403.csv
plant_file_20221013142151.csv
plant_file_20221013142455.csv
person_file_20221012134948.csv
person_file_20221012140706.csv
person_attributes_file_20221012134948.csv
person_attributes_file_20221012140706.csv
How can we sort file names in list using timestamp, so that oldest file can be loaded first and load latest file at last ?
I'm writing a program to take large PDF's and convert each page to a .jpg, then add the .jpg's of each pdf file to their own directory (which the program needs to create).
I have completed the conversion part of the program, but I am stuck on creating a directory and adding the files to the directory.
Here's my code so far.
import glob, sys, fitz, os, shutil
zoom_x = 2.0
zoom_y = 2.0
mat = fitz.Matrix(zoom_x, zoom_y) # to get better resolution
all_files = glob.glob('/Users/homefolder/Downloads/*.pdf') # image path
print(all_files)
for filename in all_files:
doc = fitz.open(filename)
head, tail = os.path.split(doc.name)
save_file_name = tail.split('.')[0]
for page in doc: # iterate through the pages
# print(page)
pix = page.get_pixmap(matrix=mat)
# render the image
filepath_save = '/Users/homefolder/Downloads/files' + save_file_name + str(page.number) + '.jpg'
pix.save(filepath_save) # save image
sample = glob.glob('/Users/homefolder/Downloads/*.jpg')
How would I write the code to create a directory for each pdf file and add those .jpg's to the directory?
You can create directory and save to it your processed files, I also refactored your code a bit:
import glob, fitz, os
zoom_x = 2.0
zoom_y = 2.0
mat = fitz.Matrix(zoom_x, zoom_y)
pdf_files = glob.glob('/Users/homefolder/Downloads/*.pdf')
save_to = '/Users/homefolder/Downloads/pdf_as_img/'
for path in pdf_files:
doc = fitz.open(path)
base_name, _ = os.path.splitext(os.path.basename(doc.name))
directory_to_save = os.path.join(save_to, base_name)
if not os.path.exists(directory_to_save):
os.makedirs(directory_to_save)
for page in doc:
pix = page.get_pixmap(matrix=mat)
filepath_save = os.path.join(directory_to_save, str(page.number) + '.jpg')
pix.save(filepath_save)
This script creates a directory for every pdf file and saves pages as jpg to it.
While trying to download sentinel image for a specific location, the tif file is generated by default in drive but its not readable by openCV or PIL.Image().Below is the code for the same. If I use the file format as tfrecord. There are no Images downloaded in the drive.
starting_time = '2018-12-15'
delta = 15
L = -96.98
B = 28.78
R = -97.02
T = 28.74
cordinates = [L,B,R,T]
my_scale = 30
fname = 'sinton_texas_30'
llx = cordinates[0]
lly = cordinates[1]
urx = cordinates[2]
ury = cordinates[3]
geometry = [[llx,lly], [llx,ury], [urx,ury], [urx,lly]]
tstart = datetime.datetime.strptime(starting_time, '%Y-%m-%d') tend =
tstart+datetime.timedelta(days=delta)
collSent = ee.ImageCollection('COPERNICUS/S2').filterDate(str(tstart).split('')[0], str(tend).split(' ')[0]).filter(ee.Filter.lt('CLOUDY_PIXEL_PERCENTAGE', 20)).map(mask2clouds)
medianSent = ee.Image(collSent.reduce(ee.Reducer.median())) cropLand = ee.ImageCollection('USDA/NASS/CDL').filterDate('2017-01-01','2017-12-31').first()
task_config = {
'scale': my_scale,
'region': geometry,
'fileFormat':'TFRecord'
}
f1 = medianSent.select(['B1_median','B2_median','B3_median'])
taskSent = ee.batch.Export.image(f1,fname+"_Sent",task_config)
taskSent.start()
I expect the output to be readable in python so I can covert into numpy. In case of file format 'tfrecord', I expect the file to be downloaded in my drive.
I think you should think about the following things:
File format
If you want to open your file with PIL or OpenCV, and not with TensorFlow, you would rather use GeoTIFF. Try with this format and see if things are improved.
Saving to drive
Normally saving to your Drive is the default behavior. However, you can try to force writing to your drive:
ee.batch.Export.image.toDrive(image=f1, ...)
You can further try to setup a folder, where the images should be sent to:
ee.batch.Export.image.toDrive(image=f1, folder='foo', ...)
In addition, the Export data help page and this tutorial are good starting points for further research.
So far I have the following:
source_folder = 'file_location'
for file in os.listdir(source_folder):
if file.startswith('stnet_'):
os.rename(file, file.replace('stnet_a_b', '%s_' % time.ctime(os.path.getctime(file)) + 'stnet_a_b'))
The issue with is is I keep getting FileNotFoundError: [WinError 2] The system cannot find the file specified 'stnet_a_b.raw'
Can someone point out what I'm doing wrong?
Thanks.
os.listdir can only get the filenames without directory, while os.rename, os.path.getctime needs full name with directory(if your current directory is not conincidently file_location then the file will not be found).
You can use os.path.join to get the full name. And if you are on Windows you must make sure filename doesn't contain special characters which your code contains.
dir = r'file_location'
# os.chdir(dir) # in case you don't want to use os.path.join
for filename in os.listdir(dir):
print(filename)
if filename.startswith('stnet_'):
src = os.path.join(dir, filename)
ctime_str = str(time.ctime(os.path.getctime(src)))
ctime_str = ctime_str.replace(':', '').replace(' ', '') # remove special characters
fn_new = filename.replace('stnet_a_b',
'{}_'.format(ctime_str + 'stnet_a_b'))
des = os.path.join(dir, fn_new)
print('src={}, des={}'.format(src, des))
os.rename(src, des)
please try above code.
In an application, I can get the path to a file which resides in a directory as a string:
"/path/to/the/file.txt"
In order to write another another file into that same directory, I want to change the string "/path/to/the/file.txt" and remove the part "file.txt" to finally only get
"/path/to/the/"
as a string
I could use
string = "/path/to/the/file.txt"
string.split('/')
and then glue all the term (except the last one) together with a loop
Is there an easy way to do it?
You can use os.path.basename for getting last part of path and delete it with using replace.
import os
path = "/path/to/the/file.txt"
delete = os.path.basename(os.path.normpath(path))
print(delete) # will return file.txt
#Remove file.txt in path
path = path.replace(delete,'')
print(path)
OUTPUT :
file.txt
/path/to/the/
Let say you have an array include txt files . you can get all path like
new_path = ['file2.txt','file3.txt','file4.txt']
for get_new_path in new_path:
print(path + get_new_path)
OUTPUT :
/path/to/the/file2.txt
/path/to/the/file3.txt
/path/to/the/file4.txt
Here is what I finally used
iter = len(string.split('/'))-1
directory_path_str = ""
for i in range(0,iter):
directory_path_str = directory_path_str + srtr.split('/')[i] + "/"
