Getting multiple error while using flask-ask and ngrok with ROS

I'm trying to use flask-ask library and develope a skill that can make me able to control a robot in ROS with alexa vocal assistant. Python code named "alexa_interface.py" is here.
The skill id number is substituted with my skill id number.
While launching this command
python3 alexa_interface.py
I am getting the following code error.
Tried to install dependencies with pip but getting:
AttributeError: module 'lib' has no attribute 'ERR_load_RAND_strings'
Also notice that I am getting this error everytime I use pip to install something. Is pip broken? How can I adjust this?
Thank you.

Chatterbot Attribute error. ChatBot object has no Attribute find

I am trying to make a chatbot with Chatterbot, Python.
I have the following code.
from chatterbot import ChatBot
from chatterbot.trainers import ChatterBotCorpusTrainer
chatbot = ChatBot('Ron Obvious')
trainer = ChatterBotCorpusTrainer(chatbot)
trainer.train("chatterbot.corpus.english")
r = chatbot.get_response("Hello, how are you today?")
print(r)
When ever I run it, it shows me the following error message.

How to fix this?

Checkov error: AttributeError: type object 'Lark' has no attribute '_load_from_dict

After upgrading python from 3.6 to 3.8 and reinstalling checkov it worked just fine.

time_func = time.clock
AttributeError: module 'time' has no attribute 'clock'

I had this issue with SQLAlchemy 1.2.10. Upgrading to the current version (1.3.18 as of now) fixed the problem
pip install sqlalchemy --upgrade

The error occurs because in python 2, there is time.clock(), but in python 3, it has been replaced with time.perf_counter().
Just replace all the time.clock to time.perf_counter, and it should be fine. For more info: https://www.webucator.com/blog/2015/08/python-clocks-explained/

I found a solution that worked for me
I have a virtual environment carpet named env in which I installed sqlalchemy
So, env\Lib\site-packages\flask_sqlalchemy_init_.py
Inside that there is this code:
if sys.platform == 'win32':
_timer = time.clock
else:
_timer = time.time
And I changed clock to perf_counter()
_timer = time.perf_counter()

import shapely.geometry throws AttributeError: function 'GEOSversion' not found

import shapely.geometry works fine in the interpreter but the code throws this error when running:
AttributeError: function 'GEOSversion' not found
Also tried
import geos
ImportError: No module named geos`
But Shapely used to run perfectly.
Have not found any post regarding this problem in SO. Any help is much appreciated. Thanks!
