How can I query the bittensor network using btcli?

btcli query
Enter wallet name (default): my-wallet-name
Enter hotkey name (default): my-hotkey
Enter uids to query (All): 18
Note that my-wallet-name, my-hotkey where actually correct names. My wallet with one of my hotkeys. And I decided to query the UID 18.
But btcli is returning an error with no specific message
AttributeError: 'Dendrite' object has no attribute 'forward_text'
Exception ignored in: <function Dendrite.__del__ at 0x7f5655e3adc0>

prog = _os.path.basename(_sys.argv[0])
TypeError: 'NoneType' object is not subscriptable
What does this means?
How can I query an UID correctly?
I have try to look for UIDs to query but the tool does not give me any.
I was expecting a semantic error or a way to look for a UID i can query but not a TypeError.

It appears that command is broken and should be removed.
I opened an issue for you here: https://github.com/opentensor/bittensor/issues/1085
You can use the python API like:
import bittensor
UID: int = 18
subtensor = bittensor.subtensor( network="nakamoto" )
forward_text = "testing out querying the network"
wallet = bittensor.wallet( name = "my-wallet-name", hotkey = "my-hotkey" )
dend = bittensor.dendrite( wallet = wallet )
neuron = subtensor.neuron_for_uid( UID )
endpoint = bittensor.endpoint.from_neuron( neuron )
response_codes, times, query_responses = dend.generate(endpoint, forward_text, num_to_generate=64)
response_code_text = response_codes[0]
query_response = query_responses[0]

SQL query within Python

I am trying to run a query within python and am running into errors.
I am extremely novice in the world of SQL, and one of our DBAs wrote this SQL command and it worked from their machine. However when I am converting it to Python is where I am running into issues.

swis = SwisClient(npm_server, username, password)
print("Query Test:")
query = """

Key Error on python & App Engine

I am developing an application on App Engine and Python. This app is meant to create routes to several points in town. To create this routes, I invoke a request to an Arcgis service. Once that is done, I need to check the status of the request and get a JSON with the results. I check these results with the following method:
def store_route(job_id, token):
import requests, json
#Process stops result and store it as json in stops_response
stops_url = "https://logistics.arcgis.com/arcgis/rest/services/World/VehicleRoutingProblem/GPServer/SolveVehicleRoutingProblem/jobs/"
stops_url = stops_url+str(job_id)+"/results/out_stops?token="+str(token)+"&f=json"
stops_r = requests.get(stops_url)
stops_response = json.loads(stops_r.text)
#Process routes result and store it as json in routes_response
routes_url = "https://logistics.arcgis.com/arcgis/rest/services/World/VehicleRoutingProblem/GPServer/SolveVehicleRoutingProblem/jobs/"
routes_url = routes_url+str(job_id)+"/results/out_routes?token="+str(token)+"&f=json"
routes_r = requests.get(routes_url)
routes_response = json.loads(routes_r.text)
from routing.models import ArcGisJob, DeliveryRoute
#Process each route from response
processed_routes = []
for route_info in routes_response['value']['features']:
print route_info
route_name = route_info['attributes']['Name']
coordinates = route_info['geometry']['paths']
coordinates_json = {"coordinates": coordinates}
#Process stops from each route
stops = []
for route_stops in stops_response['value']['features']:
if route_name == route_stops['attributes']['RouteName']:
stops.append({"Name": route_stops['attributes']['Name'],
"Sequence": route_stops['attributes']['Sequence']})
stops_json = {"content": stops}
#Create new Delivery Route object
processed_routes.append(DeliveryRoute(name=route_name,route_coordinates=coordinates_json, stops=stops_json))
#insert a new Job table entry with all processed routes
new_job = ArcGisJob(job_id=str(job_id), routes=processed_routes)
new_job.put()
As you can see, what my code does is practically visit the JSON returned by the service and parse it for the content that interest me. The problem is I get the following output:
{u'attributes': {
u'Name': u'ruta_4855443348258816',

The actual JSON returned has a lot more of info, but i just wrote a little portion of it so you can see that there IS a 'geometry' key. Any idea why I get this error??

AWS Boto: scan() unknown keyword 'limit'

Anyone come across this before?
import boto
conn = boto.dynamodb.connect_to_region('eu-west-1', aws_access_key_id=aws_key, aws_secret_access_key=aws_secret)
table = conn.get_table('TweetSample')
print table.scan(limit=1)
error:
Traceback (most recent call last):
File "test.py", line 9, in <module>
print table.scan(limit=1)
File "table.py", line 518, in scan
return self.layer2.scan(self, *args, **kw)
TypeError: scan() got an unexpected keyword argument 'limit'
[Finished in 0.4s with exit code 1]
I don't even know...

According to the documentation, scan method of boto.dynamodb.table.Table (which is returned by boto.dynamodb.layer2.Layer2.get_table) does not accepts limit, but max_results.
And the result is a generator. So, if you want to print it you should iterate it:
import boto.dynamodb
conn = boto.dynamodb.connect_to_region(
'eu-west-1',
aws_access_key_id=aws_key,
aws_secret_access_key=aws_secret)
table = conn.get_table('TweetSample')
for row in table.scan(max_results=1):
print row
or convert it to a sequence:
print list(table.scan(max_results=1))

Using nipype to apply a FLIRT registration to an additional image error

I am trying to do some registration in python using the nipype package. It worked for basic registration:
from nipype.interfaces import fsl
from nipype.testing import example_data
flt = fsl.FLIRT(bins=640, cost_func='mutualinfo')
flt.inputs.in_file = 'myInput.img'
flt.inputs.reference = 'myReference.img'
flt.inputs.out_file = 'moved_subject.nii'
flt.inputs.out_matrix_file = 'subject_to_template.mat'
res = flt.run()
This yielded a successful registration. However, I am trying to apply this registration transformation to a non-brain image in the same space as the input MRI, using the outputted flt.inputs.out_matrix_file = 'subject_to_template.mat'.
I tried the following:
from nipype.interfaces import fsl
flt = fsl.FLIRT(bins=640, cost_func='mutualinfo')
flt.inputs.in_file = 'myNonBrainImage.img'
flt.inputs.reference = 'myReference.img'
flt.inputs.out_file = 'regNonBrain.nii'
flt.inputs.in_matrix_file = 'subject_to_template.mat'
flt.inputs.apply_xfm = True
res = flt.run()
Hoping that the flt.inputs.in_matrix_file and flt.inputs.apply_xfm = True flag would override standard registration and just use the matrix to register the additional image, but I got this error:

Standard output:

Do you know why and how can I solve this?

There is a space in directory/file name containing your images:
/root/Desktop/Test Data
Rename Test Data as Test_Data and it will work
