import vtk ModuleNotFoundError: No module named 'vtkCommonCorePython'

Ok, there are multiple similar errors and no conclusive solution:
System: windows 10, conda 4.10.3, python 3.7.11
In cmd I activated conda virtual environment: conda activate tensorflow
I ran
import vtk
and got back:
ImportError Traceback (most recent call last)

ModuleNotFoundError: No module named 'vtkCommonCorePython'
Previously in conda virtual environment I ran conda install vtk and it ran fine.
My path variable contains: D:\user_data\Program_Files\Anaconda3
I also searched and found the following folder: D:\user_data\Program_Files\Anaconda3\pkgs\vtk-8.2.0-py37h1e53df8_200
How else can I troubleshoot?

import fancyimpute Runtime and ImportError

I tried
pip install tensorflow
it says it is incompatible with my numpy version(1.20.0)
Then I tried unistall numpy to required version numpy~=1.19.2
Then
pip install fancyimpute
It installed without any errors in AnacondaPromt
But it still not working in Jupyter Notebook
The Error is
---------------------------------------------------------------------------
RuntimeError Traceback (most recent call last)
RuntimeError: module compiled against API version 0xe but this version of numpy is 0xd

ImportError: numpy.core.multiarray failed to import

I had the same issue and I upgraded NumPy by running pip install numpy --upgrade. It worked around for me.

I found a solution right here
Opencv/numpy issue: "module compiled against API version X but this version of numpy is Y"
Here is the table and since my version is 1.19.5(0xd) now,
I uninstalled this version and installed 0xe version of numpy which is 1.20.0.

Python "Import missingno" results in "ImportError: attempted relative import with no known parent package"

I am using jupyter nb running python 3.9.1 using pip to install modules etc.
All imports work smoothly except missingno.
All the modules being imported are located in the same location Python39\lib\site-packages but missingno results in Import Error.
The missingno module had been imported and it has run smoothly before but after a kernel restart, the Import Error cropped up.

ImportError: attempted relative import with no known parent package
How to fix it?
I have tried to delete the missingno files and reinstalling it using pip install missingno but nothing works.
Running Python in shell and importing missingno, I still get the same error. There is nothing fancy in my code, a simple, generic import which showed no signs of error before kernel restart.
>>> import missingno

Try opening the missingno.py file in site-packages.
Change
from .utils import nullity_filter, nullity_sort
to
from utils import nullity_filter, nullity_sort

I have installed simpletransformers with success. Why is it not working? A big thank you in advance.

I answered my own question with "pip install torch" and updated the Microsoft C++ reading software. :)))

ImportError: No module named src.utils tensorflow

I am trying to load tensorflow within jupyter notebook and receive the following error:
ImportError Traceback (most recent call last) <ipython-input-1-28a19874e1dd> in <module>()
5 import tensorflow as tf
6 from tensorflow.python.framework import ops

ImportError: No module named src.utils
I have the latest tensorflow installed and have also added models to the PYTHONPATH via:
export PYTHONPATH="$PYTHONPATH:/Pathway/tfmodels-1.9.0"
Do you know how I can resolve this import error?

To resolve this import error I manually imported the missing functions from the following github repo > https://github.com/andersy005/deep-learning-specialization-coursera/blob/master/02-Improving-Deep-Neural-Networks/week3/Programming-Assignments/tf_utils.py
