How can I fix this?
You can start the notebook with:
$ sage -n
If the problem persists, try with different options for notebook (man sage):
Optional arguments:
--notebook=[...] -- start the Sage notebook (valid options are
'default', 'sagenb', 'jupyter', and 'export')
Current default is 'export' from sagenb to jupyter
-n, --notebook -- shortcut for --notebook=default

I have a script that allow me to connect to Azure ML Workspace. But it only works in local (interactive authentification) or on Cluster Instances while doing experiences.
But I can not manage to make it work in Compute Instances.

I do not want to use SDK2, it will break all my existing code.
I don't understand why the identidy is not automatically managed when starting the Compute Instances like Cluster Instances.
Does any one has a solution for this?
Use the below code blocks to connect to the existing workspace using the python SDK using the compute instances.
Create a compute instance
from azureml.core import Workspace
ws = Workspace.from_config()
ws.get_details()
Output:
Connecting to workspace using Config file:

I have a simple application that uses Google Cloud Pub/Sub, and as of a few days ago it has ceased working. Whenever I try to interact with the service (create a topic, subscribe to a topic, etc), I receive a DeadlineExceeded: 504 Deadline Exceeded error. For example:
from google.cloud import pubsub_v1
client = pubsub_v1.PublisherClient()
client.create_topic(request={"name": "test_topic"})
I have tried:
Creating new service account credentials
Lowering security on my Xfinity/Comcast router
The one thing that worked temporarily was a factory reset of the router, but then an hour later it stopped working.
Also, this problem exists across all the Python libraries for Google Cloud.
I am quite unfamiliar with networking so don't even know where to begin to solve this problem. Thanks in advance.
EDIT:
Full error

Long story short: I have been given some Python code for a custom openAI gym environment. I can successfully run the code via ExperimentGrid from the command line but would like to be able to run the entire experiment from within Jupyter notebook, rather than calling scripts. This would be more convenient for some experiments that I will be doing farther down the road.
My question: Is it possible to execute an experiment on a custom OpenAI gym environment entirely from within Jupyter Notebook and if so, how? I've seen plenty of examples of people executing gym's standard environments (like SpaceInvaders-v0 or CartPole-v0) from Jupyter but even then, they are calling the environment with
env=gym.make('SpaceInvaders-v0')
and essentially executing that environment's script behind the scenes.
Below is a basic description of how my code is set-up to run from the command line and the errors that I'm getting in Jupyter.
Any advice would be appreciated. I am admittedly rather new to Gym, Python and Linux.
My basic environment code is structured like this in, say, envs/mygames/Custom_Env.py:
various import statements (numpy, gym, pyglet, copy)
class Entity()
class State()
class The_Custom_Env(core.Env) # This is the main environment class
class Shell_Class # This class calls The_Custom_Env and provides some arguments
In mygames/__ init__.py,I import the Shell_Class:
from gym.envs.mygames.Custom_Env import Shell_Class
In envs/__ init__.py, I have the environment registered
register(
id='TEST-v0',
entry_point='gym.envs.mygames:Shell_Class',
max_episode_steps=200,
reward_threshold=25.0,)
Finally, if I execute a script containing this code from the command line, the experiment works without issue:
from spinup.utils.run_utils import ExperimentGrid
from spinup import ppo_pytorch
import torch
if __name__ == '__main__':
import argparse
parser = argparse.ArgumentParser()
parser.add_argument('--cpu', type=int, default=4)
parser.add_argument('--num_runs', type=int, default=1)
args = parser.parse_args()
eg = ExperimentGrid(name='super-cool-test')
eg.add('env_name', 'TEST-v0', '', True)
eg.add('seed', [10*i for i in range(args.num_runs)])
eg.add('epochs', [10])
eg.add('steps_per_epoch', 4000)
eg.add('ac_kwargs:hidden_sizes', [(32, 32)], 'hid')
eg.add('ac_kwargs:activation', [torch.nn.ReLU], '')
eg.add('pi_lr', [0.001])
eg.add('clip_ratio', 0.3)
eg.run(ppo_pytorch, num_cpu=args.cpu)
My Jupyter Attempt
I put all of the code from Custom_env.py in cell #1.
I then registered the environment in cell #2:
gym.register(
id='TEST-v1',
entry_point='__main__:Shell_Class',
max_episode_steps=200,
reward_threshold=25.0,)
based on this Q/A: Register gym environment that is defined inside a jupyter notebook cell
, I make the environment in cell #3:
gym.make('TEST-v1')
and get this non-descriptive output:
<TimeLimit<Shell_Class< TEST-v1 >>>
In cell #4, I tried to execute ExperimentGrid code directly within Jupyter like so:
from spinup.utils.run_utils import ExperimentGrid
from spinup import ppo_pytorch
import torch
num_runs=1
cpu=4
env_name='TEST-v1'
eg = ExperimentGrid(name='Jupyter-test')
eg.add('env_name', env_name, '', True)
eg.add('seed', [10*i for i in range(num_runs)])
eg.add('epochs', 500)
eg.add('steps_per_epoch', 4000)
eg.add('ac_kwargs:hidden_sizes', [(32, 32)], 'hid')
eg.add('ac_kwargs:activation', [torch.nn.ReLU], '')
eg.add('pi_lr', 0.001)
eg.add('clip_ratio', 0.3)
eg.run(ppo_pytorch, num_cpu=cpu)
The experiment starts up as usual but then runs into some kind of error:

There are 2 errors in the code.
We can load only datasets present in the seaborn website using sns.load_dataset as it for online CSV files on https://github.com/mwaskom/seaborn-data.
While specifying the dataset name no need to specify the extension of the dataset. Below is the sample code to load tips dataset.
import seaborn as sns
tips = sns.load_dataset("tips")
tips.head()
sns.load_dataset() searches for a dataset from online. It does not import the dataset from your working directory.
Here is the documentation for seaborn load_dataset function
Assuming that your dataset top10s.csv is located in the same folder as your python file, you should use pandas for this instead.
import pandas as pd
spotify = pd.read_csv('top10s.csv')
Be aware that you have to install this library before importing via pip like so:
pip install pandas
You'll need to install the latest master branch of zipline. You can do that by:
pip install zipline

There's an ActiveState property, which contains a state value that reflects whether the unit is currently active or not. I've succeeded in reading UnitFileState, however I can't figure out how to read ActiveState property.
After having a look at some random examples [more permanent link], I've had some luck with
import dbus
sysbus = dbus.SystemBus()
systemd1 = sysbus.get_object('org.freedesktop.systemd1',

manager = dbus.Interface(systemd1, 'org.freedesktop.systemd1.Manager')
service = sysbus.get_object('org.freedesktop.systemd1',

interface = dbus.Interface(service,
dbus_interface='org.freedesktop.DBus.Properties')
print(interface.Get('org.freedesktop.systemd1.Unit', 'ActiveState'))
[Edit:]
Documenting the versions, just in case:
dbus.version == (1, 2, 14)
systemd 244 (244.1-1-arch)
Python 3.8.1
You probably need to call dbus.Interface(sysbus.get_object('org.freedesktop.systemd1', u), 'org.freedesktop.systemd1.Unit') and access the ActiveState property on that object. Your code currently tries to access the ActiveState property on an object path, which is not the object itself.
