Answer 1

Try installing the previous version of ChatterBot.

pip install chatterbot==1.0.4

This should work, unless there are some other problems. I had the same problem and it worked for me.

There would be another problem if you are using Python 3.8.x. In Python 3.8.x, a few functions of a few modules were removed. You will be able to import ChattberBot, but when you name the bot, there will be an error.

File "C:\Python38\lib\site-packages\sqlalchemy\util\compat.py", line 264, in <module>
time_func = time.clock
AttributeError: module 'time' has no attribute 'clock'

Copy the location for the file given in the last line, where the error occurs.

C:\Python38\lib\site-packages\sqlalchemy\util\compat.py

Open file with IDLE or whatever editor you have. Please do Not open the file directly(this will run the file, and you will not be able to see the code), instead Open with IDLE or Your Text editor Then, go to line 264 in that. It would be written

time_func = time.clock

Instead of this change it to

time_func = time.perf_counter()

I Hope this helped!
