How do I resolve the kernel error in my Jupyter Notebook?

I installed jupyter notebook with pip but everytime I create a new notebook, it shows a kernel error-

This is the error that shows up everytime. I tried reinstalling jupyter as well but nothing worked. Is there a way I can use jupyter without having to install anaconda?

Coverage - PermissionError: [Errno 1] Operation not permitted

I using pytest and coverage modules for test cases and code coverage.
From the project root, I'm able to execute pytest -v but not pytest -v --cov=./ (stack trace below)
I set PYTHONPATH to the project's root directory.
Directory permissions and ownership are drwxr-xr-x and saurabh staff. Terminal application has full disk access.
My .coveragerc (located at project root) looks like:

Am I doing this the wrong way or any suggestions on how I can fix this?
Update:
When I remove data_file = tests/coverage/, the coverage command is working fine. But should this be happening, because there is an option to change the data_file here ?

I'm able to get it working by changing .coveragerc to:
[run]
omit = data-structures/*
data_file = tests/coverage/.coverage
[html]
directory = tests/coverage/html_report/
[xml]
output = tests/coverage/coverage.xml

"ValueError: option names {'--testrail'} already added" when starting autotest with pytest-alure plugin

Trying to setup pytest-testrail plugin. When I start test run using --testrail --tr-config=path/to/config.cfg param, it returns error ValueError: option names {'--testrail'} already added
im using appium+pytest+allure. It works well for me, but now im trying to add testrail integration. I setup pytest-testrail plugin correct(test run successfully created in testrail with list of my auto test), but when I add from pytest_testrail.conftest import * to my own conftest file, in return error .
I try to reinstall pytest and pytest-testrail plugin multiple times, but it doesn't help
conftest file:
import pytest
from appium import webdriver
from pytest_testrail.conftest import *

sys.path.append(os.path.join(os.path.dirname(os.path.abspath(__file__)), os.pardir, os.pardir))

here example of my test cases with all decorators:

#allure.epic('application name ')
class Test_app_name:

#allure.severity(allure.severity_level.CRITICAL)
def test_case_name(self):
page = pageObjectClassWithLocatorsAndActions(self.driver)
with allure.step('step'):
page.do_something()

It maybe duplicate with issue described here Pytest Testrail Module - Post Test Results for Test Runs
If so, you don't need to import "pytest_testrail.conftest" in your own conftest
You need assert something in "page.do_something()" to testrail plugin knows the status of "test_case_name"

I am new to docker, so I do not understand what is causing this error.
I am starting with a ubuntu as my base [this also happens when using a https://hub.docker.com/_/python/ as my base]

I have installed Python 3.5.2 in the container

The 'USER' environment variable seems not to defined within your image. Define it externally, or make your code resilient to its absence:
In your code, use os.getenv('USER', backup_user_name) instead of os.environ['USER']
In your code, use getpass instead of relying on your environment to get the current user.
import getpass
print getpass.getuser()
In docker run, you could add -e USER=$(whoami) or something of that sort
In docker-compose, you could add USER: some_user_name under the environ setting for that service.

No module named misc when implementing a simple pytest plugin?

I'm trying to implement the pytest plugin mentioned in https://github.com/pytest-dev/pytest/issues/2039, basically this plugin will print all tests that pytest finds:
## pytest_collector.py
import sys
import pytest
class DkPytestCollector(object):
def __init__(self):
self.collected = []
def pytest_collection_modifyitems(self, items):
for item in items:
self.collected.append(item.nodeid)
if __name__ == '__main__':
dkpytest_collector = DkPytestCollector()
directory = sys.argv[1]
pytest.main(['--collect-only', directory], plugins=[dkpytest_collector])
print('\n\nfound:')
for nodeid in dkpytest_collector.collected:
print(nodeid)
however, when I run it I get:
(dk) go|c:\srv\lib\dk> python ..\dkbuild\dkbuild\pytest_collector.py \srv\lib\dk

ImportError: No module named misc
if I pip uninstall pytest-cov everything works (well, except no coverage..)
How do I get this to work without uninstalling pytest-cov?
