Due to this, I can't use
import spacy
nlp = spacy.load('en_core_web_sm')
Because it is showing error as:
OSError: [E050] Can't find model 'en_core_web_sm'. It doesn't seem to be a Python package or a valid path to a data directory.
I have searched various post and articles related to it but nothing is working for me.
Can anyone tell me how to resolve this error ? It would be very helpful for me.
Good morning,
i am using tensorflow lite and i also wanted to use telepot.
I also installed the Coral USB accelerator, but I don't think it depends on him, also because it is independent of whether or not to add --edgetpu to the end of the program start command.
It works only if the transfer of messages or images I place it before this instruction:
from tensorflow.lite.python.interpreter import Interpreter
it's how telepot is incompatible with tflite.
Obviously everything works without the telepot instruction
What can I do?
I'm using a raspberry pi 4 with s.o. Debian burst, Python 3.7 and Opencv 4.1
This is the error that gives me:

I am trying to use the responses module to mock an HTTP server and I have the feeling it is broken when calls requests are multi-threaded.
Consider the following:
import json
import responses
import requests
import threading
try:
import urlparse
except ModuleNotFoundError:
import urllib.parse as urlparse
server_url = 'http://server'
headers_json = {'content-type': 'application/json'}
def init():
def endpoint(request):
id = urlparse.parse_qs(urlparse.urlparse(request.path_url).query)["id"][0]
data = {"foo": int(id)}
return 200, headers_json, json.dumps(data)
responses.add_callback(
responses.GET, server_url + '/',
callback=endpoint,
)
#responses.activate
def test():
init()
def responses_routine():
resp = requests.get(
server_url + '/?id=456',
headers=headers_json,
)
# {"foo": "456"}
print(resp.json()["foo"])
def print_routine():
print("456")
# This will print "456"
#responses_routine()
# This will print "456" after 2 seconds
#threading.Timer(2, print_routine).start()
# This will fail
threading.Timer(2, responses_routine).start()
test()
It fails with a stack that clearly indicates that no call to responses was made. The requests module did try to make an HTTP code to a remote server.

It fails on Redhat 6.6. I am using Python 3.6.6 (it also fails in 2.7 with a similar stack) with requests 2.22 and responses 0.10.6.
It's like when the main thread exited, all "handles" to responses were lost...
Any clues ?
Actually what's created within the context manager responses.activate should not escape it.
In the code above, the underlying thread of the Timer object would be joined outside the scope, hence potentially run outside the context manager scope, which yield the exception.
