I am trying to import ArrayLike doing from numpy.typing import ArrayLike, and I get the error mentioned in the title:
ModuleNotFoundError: No module named 'numpy.typing'
I know I could simply write import numpy.typing as npt as the documentation shows, but I would like the simplicity of just importing the types that I want to use. It is also not the first time that this has happened to me: I want to import a specific method/class but I'm forced to import the parent module with a nickname instead because otherwise, I get an Error. Why's that?
Re-posting the resolution in the comments above as a community wiki for better visibility:
The numpy typing module was introduced in numpy 1.20
Make sure that you have the correct numpy version by running the following at the beginning of your notebook:
%pip install -U numpy
In my case, my version of numpy was correct but I could not get rid of the error:
AttributeError: module 'numpy' has no attribute 'typing'
What helped was to directly import the module at the top of the file:
import numpy.typing
Then I was able to use either numpy.typing.ArrayLike or np.typing.ArrayLike.

When I want to import SkipWrapper It occurs an error
from gym.wrappers import SkipWrapper
ImportError: cannot import name 'SkipWrapper' from 'gym.wrappers'
I can't find any solution on the internet. I tried to downgrade gym to 0.9.5 but It also doesn't work.
Try this import
from gym.wrappers.frame_skipping import SkipWrapper
OR
Downgrade/upgrade the gym package. Source Code installed should contain the SkipWrapper class definition.
https://programtalk.com/vs2/?source=python/9609/gym/gym/wrappers/frame_skipping.py
'Monitor' has been removed from 'gym.wrappers' in gym0.23.
Running in the gym0.21, it is successful.
I would like to use Dask to create a simple clustering model. I have tried the following import statements individually (in separate cells) in Jupyter Notebooks:
import dask_ml.cluster
from dask_ml.cluster import KMeans
from dask_ml.cluster import SpectralClustering
Each of them separately resulting in the following error:
ModuleNotFoundError: No module named 'sklearn.cluster._k_means'
This seems really strange. Has anyone experienced this?
I encourage you to update Dask-ML to the latest release
I'm calling yahoo_fin.options.get_expiration_dates() from a very simple code, such that it's unlikely that I have loaded other modules with the same name.
My whole code is this:
import matplotlib.pyplot as plt
import pandas as pd
from numpy import *
from yahoo_fin import options
plt.style.use("seaborn")
expirationDates = options.get_expiration_dates("goog")
The output of the last line is:
NameError: name 'HTMLSession' is not defined
Can you help me understand what's going on?
yahoo_fin requires requests-html for a few of its functions, including the yahoo_fin.options.get_expiration_dates method. You can install it using pip (it requires Python 3.6+):
pip install requests-html
Once installed, you need to restart your Python session. This link provides information on what functionality requires requests-html.
From azure.mgmt.network.operations import NetworkSecurityGroupsOperations
ImportError: No module named operations
Error in importing submodule operations from this package
Version of the package is: azure-Mgmt-network==2.0.0 rc2
You can use code like below to import NetworkSecurityGroupsOperations:
from azure.mgmt.network.v2017_09_01.operations.network_security_groups_operations import NetworkSecurityGroupsOperations
You can get more details with this link and you can change the v2017_09_01 with which version you need.
I am tying to modify the original sklearn.CalibrationCV to create my won version. The original code has "from .utils.fixes import signature". So I did the following in my version:
from sklearn.utils.fixes import signature
but got a error:
ImportError: cannot import name signature
When check the sklearn source code on GitHub. I see the following code inside fixes.py:
try:
from inspect import signature
except ImportError:
from ..externals.funcsigs import signature
Then I did from inspect import signature directly. Still get "ImportError: cannot import name signature"
Besides how to fix this, I am also curious about why the original version can import a module that will be imported from another source? Thanks.
In python 2, the inspect module does not have a signature method.
In python 3, the inspect module does have a signature method.
This code is just trying to work with both python 2 and 3.
You may want to use the funcsigs module if you are using python 2, or use sklearn.externals.funcsigs directly (for version sklearn >= 0.17).
The accepted answer doesn't work with the latest version of sklearn.
Please install funcsigs directly using
pip install funcsigs
and use from funcsigs import signature instead.
