I have a small big problem with an app I have created, using Python and Streamlit.
The problem is that when I want to deploy it to the Heroku services, it builds, but when I try to access it, it tells me that there is an applicaiton error.
I have looked at my code, whcih on the local machine works pefectly.
Do you have any idea?

I solved the issue, it appear the problem was not in the code, but inside the command of the code for running the webapp

So I've been working on a script that a co-worker of mine made now i fixed some of his issues but i cannot seem to figure out why it only actually works when i run it in debugging mode in VSC even when i run it from a normal python shell it does not give me the output files that it does when running in debug mode does anyone know why?

Because I don't have a high enough SO reputation, unfortunately I can't simply comment this and need to make it an 'Answer'.
Changing
r= requests.get(url,verify=False, auth=HTTPBasicAuth('REMOVED', 'REMOVED))
to
r= requests.get(url,verify=False, auth=HTTPBasicAuth('REMOVED', 'REMOVED'))
will get the syntax highlighting all fixed up and may make it easier for someone smarter than me to assist you :)
Something that I've previously come across (primarily with web scraping packages) were functions that didn't play nicely with relative paths - perhaps changing them to absolute paths using os.path.abspath(".....") may help? It's a stab in the dark so that this 'Answer' actually has a potentially useful element to it, but may be an adjustment worth exploring.
I'm having trouble displaying some data from Globcolour (1), due to the projection used with the matplotlib and cartopy definition of the image.
I downloaded a Total Suspended Matter image in NetCDF format (here is the data enter link description here), and when I tried to display it, along with a coastline from the cartopy package, there is a notorious gap between the coastline and the data. As you can see below, the pixels should be next to the coastline (black line), and not surpassed into the land (yellow pixels in the flags image)
This shouldn't happen. I check using QGIS and loading directly the netcdf file the coastline is set correctly.
Initially I used a PlateeCarrer projection for the image, considering that if the image was in WGS84 they would match, but clearly they don't. I've tried using the transform option in the matplotlib function but I haven't made it work. Either the gap remains, or the coordinates of the figure change to projected ones and my data (which is in geographical coordinates) disappear.
The attributes of the NetCDF file are:
'grid_type': 'Equirectangular',
'spatial_resolution': 4.6383123,
'nb_equ_bins': 55,
'registration': 5,
'lat_step': 0.041666668,

Last thing. When loading the cartopy.crs package, this error occurs:

Could it be affecting?
we answered to Felipe by email, I copy/paste here:
A small Python script to create a map on your area from a TSM GlobColour Product (I used a monthly product to have a good coverage):
import netCDF4 as nc
import numpy as np
import matplotlib.pyplot as plt
import cartopy.crs as ccrs
fig, ax = plt.subplots(figsize=(5, 5), subplot_kw=dict(projection=ccrs.PlateCarree()))
# my region of interest
ax.set_extent([-86, -84, 9, 11])
ax.coastlines(resolution='10m', color='red')
nc_dst = nc.Dataset('L3m_20100101-20100131__GLOB_4_AV-MER_TSM_MO_00.nc')
# extent of the product
data_extent = [nc_dst.max_west_grid, nc_dst.max_east_grid,
nc_dst.max_south_grid, nc_dst.max_north_grid]
data = nc_dst.variables['TSM_mean'][:]
flags = nc_dst.variables['TSM_flags'][:]
land = flags & 8 # LAND == 3rd bit == 2^3 == 8
data_noland = np.ma.masked_where(land, data)
ax.imshow(data_noland, origin='upper', extent=data_extent)
plt.savefig('TSM_noland.png')
ax.imshow(data, origin='upper', extent=data_extent)
plt.savefig('TSM.png')
I think you are facing to 2 problems:
1) Our products may overlap some land areas because of the Level-3 rebinning during the GlobColour processing: if a 4km pixel has only the corner on the water we will fill the full pixel. We keep them because they may be usefull for some needs (for example areas where the land/water limit is varying), but in the quality flags we provide a LAND mask which could be used to remove these pixels. You can also use your own LAND mask if you prefer. The Python example below shows how to use the LAND mask.
2) I suspect that your Python code introduces an east/south shift of at least half a pixel maybe because the lat/lon arrays are for the center of each pixel but the extent needed by cartopy is the exterior limit.
GlobColour flags are defined in the Product User Guide http://www.globcolour.info/CDR_Docs/GlobCOLOUR_PUG.pdf page 76.
The GlobColour Team
Are you sure your data are in WGS84? Looking at the metadata, I only see:
'earth_radius': 6378.137
which I imply means assume a spherical Earth with radius 6378.137 km. I don't have access to your data, but I would try setting up a cartopy.crs.Globe instance with that radius.
I am updating my program under Python3 and PyQt5, I use QPrinter to associate different small texts (and also images) in a single PDF document. The Python2 and PyQt4 version of the program works well, but by passing it under PyQt5 (and QPrinter) I have a problem with the margins (they are much too wide afterwards); it seems that setPageMargins is not working well (at least not as well as in QPrinter's PyQt4 version). I wrote a little script inspired by the one present in my program:

Maybe it's a PyQt5 bug at this level, or has the syntax for using QPrinter changed in margin management?
My version of Python: 3.4.3 and my version of PyQt5: 5.2.1.
Can you help me ?
I'm working on old French Napoleonian cadastre, I've vectorized it, and now I've been studying parcels' neighborhood relation. I want to know which polygon is next to which polygon.
I tried NetworkX python library, but I did not succeed to convert my shapefile to a graph. I want to extract centroids from my polygons and trace relation between them.
I can use line shapefile or area shapefile to represent my parcels.
There is my python code:
import networkx as nx
import matplotlib.pyplot as plt
G=nx.read_shp('path/to/shp') #Read shapefile as graph
pos = {xy: xy for xy in G.nodes()}
nx.draw_networkx_nodes(G,pos,node_size=10,node_color='r')
nx.draw_networkx_edges(G,pos,edge_color='b')
plt.show()
This is my shapefile:
All right, I've fixed my problem with PySal library.
There is my code if someone need to generate some graphs!
##Définition des relations d'adjacence
qW = ps.queen_from_shapefile(str(planche)+".shp")
dataframe = ps.pdio.read_files(str(planche)+".shp")
## Affiche la matrice de voisinage complète.
Wmatrix, ids = qW.full() #ou ps.full(qW)
print("Matrice d'adjacence complète:\n", Wmatrix)
print("\n")
## pour compter le nombre de voisins que possède une parcelle:
n_neighbors = Wmatrix.sum(axis=1)
for i in range (len(n_neighbors)):
if n_neighbors[i] != 0:
print("La parcelle %i a %i voisins" %(i,n_neighbors[i]))
else:
print("La parcelle %i n'a pas de voisin" %i)
print("")
## Affiche [parcelle choisie, ses voisins]:
for i in range (len(n_neighbors)):
self_and_neighbors = [i]
self_and_neighbors.extend(qW.neighbors[i])
if self_and_neighbors[1:] == []:
print("La parcelle %i n'a pas de voisin" %i)
else:
print("Les voisins de la parcelle %i sont les parcelles " %i, self_and_neighbors[1:])
##Extractions des coordonnées des centroïds:
centroids = np.array([list(poly.centroid) for poly in dataframe.geometry])
plt.plot(centroids[:,0], centroids[:,1],'.')
for k,neighs in qW.neighbors.items():
#print(k,neighs)
#origin = centroids[k]
for neigh in neighs:

I have a file called adrese.csv that contains the first lines from another file called rezultate2.txt. For example:

www.anmb.ro/ro/files/studenti/ccoc/2/servicii.html
www.anmb.ro/ro/files/studenti/ccoc/3/aspecte.html
The file rezultate2.txt contains beside these first lines a batch of text that has the word ”abandon” in it. I need to run grep -E -o ".{0,50}abandon.{0,50}" on rezultate2.txt for each line starting with the string in adrese.csv and output everything to a file, preferably a CSV. I tried different commands but nothing worked.

Desired output is a file containing the line in adrese.csv and it's corresponding text with just the word "abandon" and the 50 chars to the left and right of it:

Managed to get what I needed with the help of a friend. The Python script below was written by Radu Eosif Mihăilescu:
#!/usr/bin/python
"""Custom work for Razvan T. Coloja, placed in the public domain by the author.
"""
import sys
MAGIC_WORD = 'abandon'
def main(argv):
with open(argv[1], 'r') as faddr:
addresses = set(l.rstrip() for l in faddr)
with open(argv[2], 'r') as fres:
the_text = set(l.rstrip() for l in fres)
for address in addresses:
for line in the_text:
if line.startswith(address):
where_found = line.find(MAGIC_WORD)
if where_found != -1:
if where_found > 50:
start_excerpt = where_found - 50
else:
start_excerpt = 0

If I got it right what you are trying to achieve (running a grep on adrese.csv for each line with "abandon" in rezultate2.txt) the following snippet should do just that:
grep -E -o ".{0,50}abandon.{0,50}" rezultate2.txt | while read LINE ; do
grep "$LINE" adrese.csv >> output.csv
done
If I have understood you correctly, this:
sed 's/,/\n/g' adrese.csv | while read text ; do grep -F "$text" rezultate2.txt ; done > output.txt
Will:
The sed will convert the csv file into single lines
The while loop will take each of those inputs
And grep through the file for them.
Each of the output will be saved into output.txt
