I am new to Python and I have downloaded the code DBN.py but there is a problem:when I was trying to load the dataset MNIST.pkl.gz.there is always an meomory error..
my code is very simple:
import cPickle, gzip, numpy
# Load the dataset
f = gzip.open('C:\Users\MAC\Desktop\mnist.pkl.gz', 'rb')
train_set, valid_set, test_set = cPickle.load(f)
f.close()
and the error is as follows:
Traceback (most recent call last):

MemoryError
I really have no idea,is it because the memory of my computer is too small? it is on windows 7,32 bits
I suspect the problem to be Spyder in this case.
As to why, I have no idea but either the process isn't allowed to allocate enugh memory outside of it's own script or it simply gets stuck in a loop some how.
Try running your code without Spyder by pasting your code into myscript.py for instance and open a terminal and navigate to the folder where you saved your script and run python myscript.py and see if that works or gives the same output.
This is based on a conversation in the comments above.

I'm trying to write the model grid from a Modflow model to a vtk output to open in Paraview.
I've used Groundwater Vistas and created the MODFLOW - USG (Unstructured Grids)
When I try to use the export function I get the following error:

Below is the code I've used:
import os
import flopy as fp
from flopy.export import vtk as fv
model_path = r'C:\Work\Models\302'
os.chdir(model_path)
# MODFLOW name file:
namefile = 'westend_Alluv3_11yr_A.nam'
mf = fp.modflow.Modflow.load(namefile,verbose=False,check=False)
# create the vtk object
vtkobj = fp.export.vtk.Vtk(mf)
Thanks
I have been using python OCR code to extract text from the image but i am getting some error. I think error is with subprocess library, however it is built in library. So i couldn't figure out the error exactly. can anyone please help me in resolving this error. My code and error are as below.
OCR code
import os
import tempfile
import subprocess
def ocr(path):
temp = tempfile.NamedTemporaryFile(delete=False)
process = subprocess.Popen(['tesseract', path, temp.name], stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
process.communicate()
with open(temp.name + '.txt', 'r') as handle:
contents = handle.read()
os.remove(temp.name + '.txt')
os.remove(temp.name)
return contents
str = ocr("C:\\Users\\hp\\Desktop\\MS Thesis\\opencv-text-detection\\opencv-text-detection\\images\\sign.jpg")
print(str)
by executing th above code I got following error

FileNotFoundError: [WinError 2] The system cannot find the file specified
I have been using Python 3.7.1 with anaconda on window 7
Look like there is an error because it cannot found the file
if the file is in the same directory I will recommend you use:
import os
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
os.path.join(BASE_DIR, 'file_dir')
I am trying to change the contents of a destination file with the help of some source file. When the work is done, I am making sure that I have closed all the files in code (ofcourse, I have made sure that it is not opened in any editor too.)
def write_to_file(self, _source_path, _destination_path):
f_source = open(_source_path, 'r')
f_destination = open(_destination_path, 'r')
f_temp = open(self.temp_path, 'w+')
while source_line or destination_line:...
f_temp.close()
f_destination.close()
f_source.close()
shutil.move(self.temp_path, _destination_path)
return
I am getting below error:

PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'C:\\auto_nv_merge.xml'
C:\auto_nv_merge.xml is my temp file.
When working with
PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'C:\\auto_nv_merge.xml'
you have 2 options, be a hero and try to hunt down the process that is holding that file hostage or just restart your computer.
I usually go with the latter, restart
I am trying to write a program in python that will convert a .ui file in the same folder (created in Qt Designer) into a .py file. This is the code for this extremely basic program:
# -*- coding: utf-8 -*-
from PyQt4 import uic
with open('exampleinterface.py', 'w') as fout:
uic.compileUi('exampleinterface.ui', fout)
It gives the following error (with long path names shortened):
Traceback (most recent call last):

self._root = parser._parse_whole(source)

Can anyone tell me why this isn't working, and if there is a solution?
Note: I know that there are other ways to convert a .ui file into a .py file, but I am looking for one that I can easily integrate into a python program, without calling an outside file.
This error popped because my .ui file was not saved with the recent changes that i had done. The file name showed the asterisk(*) mark in the file name. Once i saved the file with changes it could be converted into a .py file.
Thanks to ekhumoro and mwormser. The problem was indeed the .ui file.
I retried it with a new .ui file and everything worked fine.
I have lots of csv files contained in different 7z files. I want to find specific csv files in those 7z files and save them decompressed in a different directory.
I have tried
import os
import py7zlib
tree = r'Where_the_7zfiles_are_stored'
dst = r'Where_I_want_to_store_the_csvfiles'
for dirpath, dirname, filename in os.walk(tree):
for myfile in filename:
if myfile.endswith('2008-01-01_2008-04-30_1.7z'):
myZip = py7zlib.Archive7z(open(os.path.join(dirpath,myfile), 'rb'))
csvInZipFile = zip(myZip.filenames,myZip.files)
for myCsvFileName, myCsvFile in csvInZipFile:
if '2008-01' in myCsvFileName:
with open(os.path.join(dst,myCsvFileName),'wb') as outfile:
outfile.write(myCsvFile.read())
but I get the following error

The odd thing is that the method seems to work fine for the first two csv files. I have no idea how to get to the root of the problem. At least the data in the csv files do not seem to be different. Manually unpacking the different csv files using IZArc goes without problem. (The problem occurred in both python 2.7 and 3.4).
I have also tried to use the lzma module, but here I could not figure out how to retrieve the different csv files contained in the 7z file.
