What I understood on reading other threads about similar kind of problems , that this is due to having two python versions installed
So, I tried manually removing all python files (as I was unable to uninstall python) and then uninstalled and reinstalled anaconda (spyder) but the problem persists
Any kind of help wd be appreciated
Short answer: To fix this problem, you need to remove or rename this file:
C:\Users\ABCD\email.py
Long answer: That file has the same name of a core Python module. Since it's placed in your home directory, it has higher priority than that module, which makes Python to use it first and ends up causing the error.

I tried uninstalling and reinstalling the package.

I tried reinstalling everything and searching on google but I can't find a solution.
I suppose there is an error when it looks for api=31 because it stops there.
I also tried with google collab and it gives me the same error
I thought that bazel runs tests in sandbox, but recently I got an error pointing to a local module /usr/lib/python3/dist-packages/OpenSSL/SSL.py. It it correct? How to make bazel run in a sandbox?

I had the same problem. "activate base" didn't help, but just found a solution. Certainly not quite correct, but it works.
Go to folder:
C:\Users\<your_login>\AppData\Roaming\Python
and rename it ("Python") on "Python_x" or something else.
Spyder and Navigator starts up and so far everything works, but don't delete that folder.
In cmd try activating the base environment(or any other relevant environment) by running
activate base
and then try running spyder.
I recently installed NVIDIA CUDA and test run a code :
from numba import cuda
from numba import *
import numpy as np
from pylab import imshow, show
from timeit import default_timer as timer
But I got this error in ubuntu 16.0.4. How can I resolve this error:

CudaSupportError: Error at driver init:
CUDA driver library cannot be found.
If you are sure that a CUDA driver is installed,
try setting environment variable NUMBA_CUDA_DRIVER
with the file path of the CUDA driver shared library.
Try to introduce following variables
export NUMBAPRO_NVVM=/home/cuda-7.5/nvvm/lib64/libnvvm.so
export NUMBAPRO_LIBDEVICE=/home/cuda-7.5/nvvm/libdevice/
in your .bashrc file which is usually located in home/username/
In your case the paths above should be corrected in accordance to your cuda installation paths. Note, that even if you use just umba, not numbapro the names of the variables should be as shown above.
