noob question series...
I am a new learner of python, recently want to create a small python application that can collect photos from flickr based on different search input. (eg: if i input "dog", it will download all dog images from flickr)
I did some research online and notice that flickr API might be the best way and the method flickr.photos.getSizes should be the one I need to use.
However, I have few stupid questions when coding:
I have applied my key and secret for flickr API, I just don't know what to do next with flickr.photos.getSizes in python to download photos. Like, how to call this method in python? (and I noticed required arguments for this method are keys and photo_id, how to get photo_ids based on search input "dog")
Then I followed a tutorial from https://github.com/alexis-mignon/python-flickr-api/wiki/Tutorial but when I imported flickr_api I got error message:
Could not load all modules
<class 'ImportError'> No module named 'objects'
Traceback (most recent call last):
File "D:/Agfa/Projects/Image/flickr.py", line 2, in <module>
import flickr_api
File "D:\Application\Anaconda3\lib\site-packages\flickr_api\__init__.py", line 32, in <module>
from auth import set_auth_handler
ImportError: cannot import name 'set_auth_handler'
Then I took a look at the _ init _.py:
try:
from objects import *
import objects
import upload as Upload
from upload import upload, replace
except Exception as e:
print "Could not load all modules"
print type(e), e
from auth import set_auth_handler
from method_call import enable_cache, disable_cache
from keys import set_keys
from _version import __version__
Seems like this library does not support python 3 but I don't know what to do. (I cannot install methond_call, keys, _version on my python 3) guess I will use flickrapi
Thank you so much for your time and again thanks in advance.
I think I finally got the proper way to use FlickrAPI:
there are many ways but I figured out 2:
def flickr_walk(keyward):
count = 0
photos = flickr.walk(text=keyward,
tag_mode='all',
tags=keyward,
extras='url_c',
per_page=100)
for photo in photos:
try:
url=photo.get('url_c')
urllib.request.urlretrieve(url, path+'\\' + str(count) +".jpg")
except Exception as e:
print('failed to download image')
flickr.walk uses Photos.search API, I can use the API directly as well:
def flickr_search(keyward):
obj = flickr.photos.search(text=keyward,
tags=keyward,
extras='url_c',
per_page=5)
for photo in obj:
url=photo.get('url_c')
photos = ET.dump(obj)
print (photos)
Remember to get the key and secret first:
api_key = 'xxxxxxxxxxxxxxxx'
api_secret = 'xxxxxxxxxxxxx'
flickr=flickrapi.FlickrAPI(api_key,api_secret,cache=True)
I dont have any clue on the why/how. If you want to use the flickr_api module with python3.5+, you need to fix the Imports, like I did below:
try:
from objects import *
import objects
import upload as Upload
from upload import upload, replace
except Exception as e:
#print "Could not load all modules"
print( type(e), e)
from .auth import set_auth_handler
from .method_call import enable_cache, disable_cache
from .keys import set_keys
from ._version import __version__
After this edit, it fails with another Import Error on:
>>> import flickr_api
<class 'SyntaxError'> invalid syntax (method_call.py, line 50)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/krysopath/.local/lib/python3.5/site-packages/flickr_api/__init__.py", line 32, in <module>
from .auth import set_auth_handler
File "/home/krysopath/.local/lib/python3.5/site-packages/flickr_api/auth.py", line 43, in <module>
import urlparse
ImportError: No module named 'urlparse'
So you can fix this by yourself, if you want to, by just walking along the Import Errors and adding a dot to convert them into absolute Imports, that dont fail.
I guess, if you want to use this modul you have to fix it first... and have an unknown return. So if you didnt already invested heavily, it might be more effective to use that other module.

You didn't define video before the call to Trim which takes it as a parameter.
The example script in the documentation says you need to create a video object, for example, by loading a file:
from vapoursynth import core
video = core.ffms2.Source(source='Rule6.mkv')
This loads a video file Rule6.mkv using the ffms2 plugin, which it assumes is installed correctly.
I know this question has been asked countless times here, but I've been stuck with this problem for a long time and have not been able to find a solution online.
I have an import cycle, and here is the stack trace:
Traceback (most recent call last):
File "openldap_lookup.py", line 2, in <module>

import pure.authorization.auth as auth
AttributeError: 'module' object has no attribute 'auth'
I import modules only; I avoid the from <module> import <class> and from <module> import <method>
I tried to reproduce the error locally, but python has no complaints. These are the local test files:
openldap_lookup.py
import ds_lookup
def openldap_foo():
print ds_lookup.ds_foo
print 'openldap_lookup importing ds_lookup'
ds_lookup.py
import auth as au
def ds_foo():
print au.auth_foo
print 'ds_lookup importing auth'
auth.py
import auth_unix
def auth_foo():
print auth_unix.auth_unix_foo
print 'auth importing auth_unix'
auth_unix.py
import ad_lookup
def auth_unix_foo():
print ad_lookup.ad_foo
print 'auth_unix importing ad_lookup'
ad_lookup.py
import auth as au
def ad_foo():
print au.auth_foo
print 'ad_lookup importing auth'
But python doesn't complain:
myname#myname-mbp:~/cycletest$ python openldap_lookup.py
ad_lookup importing auth
auth_unix importing ad_lookup
auth importing auth_unix
ds_lookup importing auth
openldap_lookup importing ds_lookup
myname#myname-mbp:~/cycletest$
I am not a python expert, but I understand that an import cycle is causing the error. But why doesn't the same error occur with the small test files? When is an import cycle legal in python and when is it not? What can I do to resolve this?
I would greatly appreciate any help from the python experts out there.
Since many are bound to ask, why do I have this cycle in the first place?
Well, openldap_lookup and ad_lookup both contain subclasses of a base class in ds_lookup. ds_lookup requires constants from auth. auth requires auth_unix as an implementation, and auth_unix in turn calls the implementations openldap_lookup and ad_lookup.
I would love to move the constants out from auth and remove the cycle, but this code is part of a large git repo where hundreds of files depend on the constants and methods in auth, and I would like to avoid having to refactor all of them if possible.
Actually, you're not just importing modules -- you're importing modules from packages, and your test case doesn't actually reflect this.
I think the problem is that in your first import of pure.authorization.auth, the interpreter is still building the pure.authorization module (it hasn't yet bound auth into pure.authorization, because it hasn't finished importing auth), so the second time it encounters this, it finds the pure.authorization module, but there is no global variable auth in it yet.
As far as breaking the cycle goes, does auth really need to import auth_unix right away, or could that be deferred until you really need an auth implementation?
from a ubuntu machine I use beatbox python package to connect to SF and get the objects descriptions
but can't manage to get access to the ForecastingItems object.
I checked my privileges to access the object and I have full access as admin
the script I'm using is bellow, when I changed the object ForecastingItem with Account it does pull all the object fields.
#!/usr/bin/python
# coding=utf8
import beatbox
import pprint
import sys
import os
import datetime
sf_service = beatbox.PythonClient()
sf_service.login('email#hotmail.com', 'password$numbersletter')
desc_obj = sf_service.describeSObjects('ForecastingItem')
forcat_item = desc_obj[0]
forItem_fields = forcat_item.fields
for sf_field_key, sf_field_value in forItem_fields.items():
print sf_field_key
I heard that I should upgrade beatbox to something more than the version 21 to be able to access the ForecastingItem object so I tried apt-get update upgrade beatbox, but I still get the error :
Traceback (most recent call last):
File "./fields_associated_with_an_object.py", line 14, in <module>

Your problem is circular imports.
In cardreader, you do this:
import ATRdb as ATR
That starts importing ATRdb, but a few lines into the code, it hits this:
import cardreader
The exact sequence from here depends on whether cardreader.py is your main script or not, and on whether your top-level code that calls main is protected by an if __name__ == '__main__' guard (and assuming that top-level code is in cardreader rather than elsewhere). Rather than try to explain all the possibilities in detail (or wait for you to tell us which one matches your actual code), let's look at what we know is true based on the behavior:
In some way, you're calling main before finishing the import of ATRdb.
This means that, at this point, ATRdb has nothing in it but sys, MYSQLdb, and datetime (and a handful of special attributes that every module gets automatically). In particular, it hasn't gotten to the definition of checkPerms yet, so no such attribute exists in the module yet.
Of course eventually it's going to finish importing the rest of ATRdb, but at that point it's too late; you've already called main and it tried to call ATR.checkPerms and that failed.
While there are various complicated ways to make circular imports work (see the official FAQ for some), the easiest and cleanest solution is to just not do it. If ATRdb needs some functions that are in cardreader, you should probably factor those out into a third module, like cardutils, that both ATRdb and cardreader can import.
I installed everything as it says on the FlickrAPI homepage but when I try to run:
import flickrapi
api_key = '1a4c975fa83048436a2086bcab7d2290'
api_password = '5e069eae20e60297'
flickrclient = flickrapi.FlickAPI(api_key, api_password)
favourites = flickrClient.favorites_getPublicList(user_id='userid')
photos = flickr.photos_search(user_id='73509078#N00', per_page='10')
sets = flickr.photosets_getList(user_id='73509078#N00')
for photo in favourites.photos[0].photo:
print photo['title']
I get this message from the command prompt:
C:\Users\Desktop>python api.py
Traceback (most recent call last):
File "api.py", line 4, in <module>
flickrclient = flickrapi.FlickAPI(api_key, api_password)
AttributeError: 'module' object has no attribute 'FlickAPI'
Any ideas?? I have tried almost everything
FlickAPI is not the same as FlickrAPI. You're missing an r.
The file C:\Users\XXXXXX\Desktop\FLICKR API\flickrapi.py is not part of the flickrapi package. Please rename it, it is masking the real library. Right now it is being imported instead of the installed package.
The flickrapi package itself consists of a directory with a __init__.py file inside of it. Printing flickrapi.__file__ should result in a path ending in flickrapi\__init__.py.
In your "flickrclient = flickrapi.FlickAPI" line, you're missing an 'r' in FlickAPI.
Also, on the next line, your *"user_id='userid'"* argument needs an actual user ID, such as '999999#N99'
Hopefully you found that & got this working a few months ago! :)
