I am trying to make the call
from azure.storage.fileshare import ShareDirectoryClient
shrdDirClient = ShareDirectoryClient.from_directory_url
(detailedFileURI,snapshot=None, credential=None)
but resulted in the error above.
I tried
if hasattr(ShareDirectoryClient, 'from_directory_url'):
print("Present")
But it did not go into the loop.
My full code is too long. This is another approach I tried resulting in 'str' object is not callable error
from azure.storage.fileshare import ShareDirectoryClient
from datetime import timedelta,datetime
now = datetime.now(timezone('UTC'))
sasToken = generate_share_sas(accountName, shareName, accountKey,\
permission=AccountSasPermissions(read=True, \
write=False, \
delete=False, \
list=True, create=True), expiry=now + timedelta(days=3650)\
)
accountURL = "https://nsclusterhdistorage.file.core.windows.net"
shareName = "dev-archived-data"
detailedFileURI = accountURL+'/'+shareName
sh = ShareDirectoryClient()
sh.from_directory_url(detailedFileURI,snapshot=None, credential=sasToken)
I am relatively new to python azure storage file share.
can someone help
Sorry, I can't reproduce this.
I ran the following code:
from azure.storage.fileshare import ShareDirectoryClient
detailedFileURI = "Something"
shrdDirClient = ShareDirectoryClient.from_directory_url(detailedFileURI,snapshot=None, credential=None)
and it generated the following error:
Traceback (most recent call last):
File "D:\StackOverflow\azure_storage_test.py", line 4, in <module>
shrdDirClient = ShareDirectoryClient.from_directory_url(detailedFileURI,snapshot=None, credential=None)
File "C:\Python37\lib\site-packages\azure\storage\fileshare\_directory_client.py", line 164, in from_directory_url
credential=credential, **kwargs)
File "C:\Python37\lib\site-packages\azure\storage\fileshare\_directory_client.py", line 96, in __init__
raise ValueError("Please specify a share name.")
ValueError: Please specify a share name.
Now clearly this isn't successful execution. If I'm honest, I don't know what to set detailedFileURI to. But that's not the point. The point is that the code sample above is enough to prove that I can get in to the from_directory_url method, and this is clear from the traceback.
However, if I run the following code:
from azure.storage.fileshare import ShareDirectoryClient
ShareDirectoryClient = "some string"
detailedFileURI = "Something"
shrdDirClient = ShareDirectoryClient.from_directory_url(detailedFileURI,snapshot=None, credential=None)
then I do encounter the same error:
Traceback (most recent call last):
File "D:\StackOverflow\azure_storage_test.py", line 5, in <module>
shrdDirClient = ShareDirectoryClient.from_directory_url(detailedFileURI,snapshot=None, credential=None)
AttributeError: 'str' object has no attribute 'from_directory_url'
Of course, there's not a lot of point in importing ShareDirectoryClient if you're then going to assign a string to it. You may as well remove the import statement. However, doing this reproduces your error message. In the absence of any further code in your question I can only conclude that your code does the same as this, although perhaps more subtly.
The only other suggestion I have is that your installation of the azure-storage-file-share package has somehow got broken. If you run a Python script containing the following two lines only, you should get either <class 'type'> or <class 'str'> as output. I get <class 'type'>, and I would expect that anyone else using this package would get the same. However, if you get <class 'str'>, then it is likely that the package has got corrupted and you may want to try reinstalling it.
from azure.storage.fileshare import ShareDirectoryClient
print(type(ShareDirectoryClient))
For some reason ‘ ShareDirectoryClient’ is of type {string}. You either import it as a string, i.e. ‘ azure.storage.fileshare’ simply has this defined as a string, or, you assign it to a string later in your code (not visible in the part that has been shared). Please try this:
X = ‘some_string’
X()
… and you will get the string-is-not-callable error which means a string cannot be invoked (i.e. it is not a function one can call)
Then another experiment:
Y = ‘another_string’
Y.bla()
… and you get the other error that a string object has no attribute named ‘bla’.
In Python everything is an object. If you define
class MyClass()
pass
And then try ‘MyClass.bla()’ you will get MyClass does does not have attribute ‘bla’.
Can you try to import ShareDirectoryClient and then type(ShareDirectoryClient) and we’ll see what type of object gets imported.

I'm running a code and it gives me an error I can't solve !
how can I add the missing attribute?
the relevant part of the code :
ALL_FILES = provider.getDataFiles('indoor3d_sem_seg_hdf5_data/all_files.txt') #line 63
room_filelist = [line.rstrip() for line in open('indoor3d_sem_seg_hdf5_data/room_filelist.txt')]
The error:
Traceback (most recent call last):
File "E:\Research\Codes\pointnet\pointnet-master\sem_seg\train.py", line 63, in <module>
ALL_FILES = provider.getDataFiles('indoor3d_sem_seg_hdf5_data/all_files.txt')
AttributeError: module 'provider' has no attribute 'getDataFiles'
First, check if you have import provider in your code, you can also do from model import *
I found out that you are using pointnet. So I search the source code and I found this method is:
def getDataFiles(list_filename):
return [line.rstrip() for line in open(list_filename)]
You can search your library for this method. It might not be in the provider.py
You could just added this method to your code. But the best idea is to search for it.
For you case, the provider.py should be at \pointnet\pointnet-master\, and there is also a train.py at that location.
Problem solved ! All I had to do is to copy the provider.py file into the sem.seg.py file which I used. It appears it couldn't find it in the previous file.
I'm trying to launch AWS EMR cluster using boto library, everything works well.
Because of that I need to install required python libraries, tried to add bootstrap action step using boto.emr.bootstrap_action
But It gives error below;
Traceback (most recent call last):
File "run_on_emr_cluster.py", line 46, in <module>
steps=[step])
File "/usr/local/lib/python2.7/dist-packages/boto/emr/connection.py", line 552, in run_jobflow
bootstrap_action_args = [self._build_bootstrap_action_args(bootstrap_action) for bootstrap_action in bootstrap_actions]
File "/usr/local/lib/python2.7/dist-packages/boto/emr/connection.py", line 623, in _build_bootstrap_action_args
bootstrap_action_params['ScriptBootstrapAction.Path'] = bootstrap_action.path AttributeError: 'str' object has no attribute 'path'
Code below;
from boto.emr.connection import EmrConnection
conn = EmrConnection('...', '...')
from boto.emr.step import StreamingStep
step = StreamingStep(name='mapper1',
mapper='s3://xxx/mapper1.py',
reducer='s3://xxx/reducer1.py',
input='s3://xxx/input/',
output='s3://xxx/output/')
from boto.emr.bootstrap_action import BootstrapAction
bootstrap_action = BootstrapAction(name='install related packages',path="s3://xxx/bootstrap.sh", bootstrap_action_args=None)
job = conn.run_jobflow(name='emr_test',
log_uri='s3://xxx/logs',
master_instance_type='m1.small',
slave_instance_type='m1.small',
num_instances=1,
action_on_failure='TERMINATE_JOB_FLOW',
keep_alive=False,
bootstrap_actions='[bootstrap_action]',
steps=[step])
What's the proper way of passing bootstrap arguments?
You are passing the bootstrap_actions argument as a literal string rather than as a list containing the BootstrapAction object you just created. Try this:
job = conn.run_jobflow(name='emr_test',
log_uri='s3://xxx/logs',
master_instance_type='m1.small',
slave_instance_type='m1.small',
num_instances=1,
action_on_failure='TERMINATE_JOB_FLOW',
keep_alive=False,
bootstrap_actions=[bootstrap_action],
steps=[step])
Notice that the ``bootstrap_action` argument is different here.
I'm trying to make a mixWord function and I'm getting an error saying
NameError: name 'word' is not defined
What am I missing from here?
def mixWord(word):
characterList = list(word);
print characterList
import random;
random.shuffle(characterList);
print characterList;
shuffledWord = ''.join(characterList);
print shuffledWord;
Traceback (most recent call last):
File "", line 1, in
mixWord (word)
NameError: name 'word' is not defined
The problem is PEBKAC - exactly what form, is for you to find out.
That is, the code executed is not the same as the code posted; the posted code works as expected:
def mixWord(word):
characterList = list(word);
print characterList
import random;
random.shuffle(characterList);
print characterList;
shuffledWord = ''.join(characterList);
print shuffledWord;
mixWord("PEBKAC")
So, find out why:
Has the file been saved?
Has the file been saved to the correct location?
Is the file from the correct location being run?
Is the error from different code entirely?
Also try running the code directly from an IDLE buffer as that should be immune to the previous potential issue(s).
After resolving the issue, consider updating the code to not using semicolons as they are not required here and it is un-Pythonic.
I think the problem is that you are calling mixWord(word) without defining any word variable.
I have been stuck with this error for a couple of hours now. Not sure what is wrong. Below is the piece of code
NameError: global name 'GetText' is not defined
class BaseScreen(object):
def GetTextFromScreen(self, x, y, a, b, noofrows = 0):
count = 0
message = ""
while (count < noofrows):
line = Region(self.screen.x + x, self.screen.y + y + (count * 20), a, b)
message = message + "\n" + line.text()
count += 1
return message
class HomeScreen(BaseScreen):
def GetSearchResults(self):
if self.screen.exists("Noitemsfound.png"):
return 'No Items Found'
else:
return self.GetTextFromScreen(36, 274, 680, 20, 16)
class HomeTests(unittest.TestCase):
def test_001S(self):
Home = HomeScreen()
Home.ResetSearchCriteria()
Home.Search("0009", "Key")
self.assertTrue("0009" in Home.GetSearchResults(), "Key was not returned")
Basescreen class has all the reusable methods applicable across different screens.
Homescreen inherits Basescreen.
In HomeTests test case class, the last step is to Home.GetSearchResults() which in turn calls a base class method and the error.
Note:
I have another screenclass and testcaseclass doing the same which works without issues.
I have checked all the importing statements and is ok
'GetText' in the error message is the name of method initially after which i changed it to GetTextFromScreen
Error message is still pointing to a line 88 in code which is not there any more. Module import/reloading issue?
Try clearing out your *.pyc files (or __pycache__ if using 3+).
You asked:
Error message is still pointing to a line 88 in code which is not there any more. Module import/reloading issue?
Yes. The traceback (error messages) will show the current (newest saved) file, even if you haven't run it yet. You must reload/reimport to get the new file.
The discrepancy comes from the fact that traceback printouts read from the script file (scriptname.py) saved on your drive. However, the program is run either from the module saved in memory, or sometimes from the .pyc file. If you fix an error by changing your script, and save it to your drive, then the same error will still occur if you don't reload it.
If you're running interactively for testing, you can use the reload function:
>>> import mymodule
>>> mymodule.somefunction()
Traceback (most recent call last):
File "mymodule.py", line 3, in somefunction
Here is a broken line
OhNoError: Problem with your file
Now, you fix the error and save mymodule.py, return to your interactive session, but you still get the error, but the traceback shows the fixed line
>>> mymodule.somefunction()
Traceback (most recent call last):
File "mymodule.py", line 3, in somefunction
Here is the fixed line
OhNoError: Problem with your file
So you have to reload the module:
>>> reload(mymodule)
<module 'mymodule' from '/path/to/mymodule.py'>
>>> mymodule.somefunction()
Success!
I'm running python2.5 and trying to use the astLib library to analyse WCS information in astronomical images. I try and get the object instanciated with the following skeleton code:
from astLib import astWCS
w = astWCS.WCS('file.fits') # error here
where file.fits is a string pointing to a valid fits file.
I have tried using the alternate method of passing a pyfits header object and this fails also:
import pyfits
from astLib import astWCS
f = pyfits.open('file.fits')
header = f[0].header
f.close()
w = astWCS.WCS(header, mode='pyfits') # error here also
The error is this:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/home/astro/phrfbf/build/lib/python2.6/site-packages/astLib/astWCS.py", line 79, in __init__
self.updateFromHeader()
File "/home/astro/phrfbf/build/lib/python2.6/site-packages/astLib/astWCS.py", line 119, in updateFromHeader
self.WCSStructure=wcs.wcsinit(cardstring)
File "/home/astro/phrfbf/build/lib/python2.6/site-packages/PyWCSTools/wcs.py", line 70, in wcsinit
return _wcs.wcsinit(*args)
TypeError: in method 'wcsinit', argument 1 of type 'char *'
When I run in ipython, I get the full error here on the pastebin
I know the astWCS module is a wrapped version of WCStools but i'd prefer to use the Python module as the rest of my code is in Python
Can anyone help with this problem?
Just found out the updated version of this library has fixed the problem, thanks for everyone's help
Oh sorry, I should have seen. Looking at the pastebin in more detail, the only error I can think of is that, for some reason the header has unicode in it. It can't be converted to char *, and you get the error. I tried searching for something in the header, but everything looks okay. Can you do this and post the output in another pastebin?
import pyfits
f = pyfits.open('file.fits')
header = f[0].header
f.close()
for x, i in enumerate(header.iteritems()):
if len(str(i[1])) >= 70:
print x, str(i[1])
cardlist = header.ascardlist()
cardstring = ""
for card in cardlist:
cardstring = cardstring + str(card)
print repr(cardstring)
Or, if you can check the header of your fits file for "funny" characters, getting rid of them should solve the issue.
