Why does Importing Pennylane give out cannot import name "shape" - python

I am trying to import Pennylane in jupyter notebook. I installed it using Ubuntu.
import pennylane as cents
However, it is spewing out this:
ImportError: cannot import name 'shape'
I found two reasons online. One is that python needs to be at version less than 3.7[https://github.com/PennyLaneAI/pennylane/issues/1922]. To solve this I used pip install -U jupyter. Another reason is that Pennylane might be at a version earlier enough that it had a bug[https://discuss.pennylane.ai/t/importerror-cannot-import-name-shape/1383]. I installed Pennylane to the latest version I could find, 0.25. I did pip install pennylane==0.25 But it still does not work
Could someone please explain this to me?

Cannot import name 'get_cloud_client' from 'gretel_client'

I keep getting the error
Cannot import name 'get_cloud_client' from 'gretel_client'
when I import using
from gretel_client import get_cloud_client
client = get_cloud_client(prefix="api", api_key="prompt")
client.install_packages()
I have followed all documentation and tutorials which say to just install using
!pip install -U gretel-client
and I have checked that the package exists using
!pip freeze
However it still cannot load it. Does anyone know why?
This is the only package I am having trouble with loading, everything else is fine.
It seems like this is the older way of using gretel_client.
You have two options, either to install and use an older version of the library:
pip install gretel-client==0.7.13
Or learn how to use the latest version of the library, the docs might be helpful:

spacy ImportError: cannot import name Deque in Jupyter Notebook

I want to use spacy in a Python project on Juptyer Notebook but when i try to import the module I get the Error "ImportError: cannot import name Deque". I installed spacy in PyCharm in my virtual env via pip install -U spacy
I've seen another question on here that was similar (ImportError cannot import name Deque with spacy) but I can import spacy in PyCharm just fine so I assume it's a Jupyter Notebook specific problem.
I also checked the spacy version on PyCharm and JN and they're both the same, however it seems like my virtual env and JN don't use the same Python Version (3.8.1 in my venv on PyCharm and 3.6.0 on JN)
[Python Versions in PyCharm and JN]
May that be the problem or is something else causing it?
I also tried to uninstall and install again in PyCharm but it didn't change anything and also tried to pip install spacy in JN again but that also didn't solve it, JN told me I might have to restart the kernel but after restarting it still couldn't import spacy without that error.
I've tried so much that after some time i just get the error ImportError: cannot import name errors but I assume it's still the same problme.
I'm very grateful for any suggestions and tips!
So for future references:
I just 'solved' this problem by making a new environment with Python 3.6 since afaik Jupyter Notebook doesn't support Python versions highter than 3.6.x as of now yet, set up a new venv and now both PyCharm and JN use the same Python version (3.6.12) and I could successfully import spacy.
So I'm assuming the different Python versions really were the problem.
Maybe it's not even necessary to create a new venv and everything but I wanted to start clean again to not have further problems.

Error import with 'shamilton_filter_log' from 'statsmodels.tsa.regime_switching._hamilton_filter'

I tried to compile MarkovSwitching.py from statsmodels (link description here) in python, but I have the follwoing error,
ImportError: cannot import name 'shamilton_filter_log' from 'statsmodels.tsa.regime_switching._hamilton_filter' (C:\Users\myuser\Anaconda3\lib\site-packages\statsmodels\tsa\regime_switching\_hamilton_filter.cp37-win_amd64.pyd)
And I don't kown how solve this. Furthermore, I upgrade the statsmodels using '' pip install statsmodels --upgrade'', but doesn't work.
I don't know how to solve this problem, any help is welcome!
Thanks!
It's very hard to tell from your description what might be going wrong, since there could be many problems with your setup.
It looks like maybe you have installed Statsmodels v0.10 via Conda or pip and have then downloaded the development version of markov_switching.py. The development version has new functions that v0.10 does not have, and this is my guess about why you are getting the error.
You might try installing the release candidate of v0.11, using: pip install statsmodels==0.11.0rc1.

Encountering Import Error DLL load failed constantly

I have been trying to intall scikit-learn and pytorch using their respective commands given in the docs:
The commands for installing PyTorch are:
1) pip3 install https://download.pytorch.org/whl/cpu/torch-1.0.1-cp37-cp37m-win_amd64.whl
2) pip3 install torchvision
The command for installing scikit-learn is:
pip install -U scikit-learn
Some background:
I am using Windows 8.1, Python 3.7.2. My pip is updated. I have also installed Anaconda for solving this using conda, but had zero luck!(Also, here I am running into 'conda' unrecognized error which is another story). Here are the paths my PATH variable holds.
PATH
C:\Users\satya\Anaconda3;
C:\Users\satya\Anaconda3\Library\mingw-w64\bin;
C:\Users\satya\Anaconda3\Library\usr\bin;
C:\Users\satya\Anaconda3\Library\bin;
C:\Users\satya\Anaconda3\Scripts;
C:\Users\satya\AppData\Local\Programs\Python\Python37\Scripts\;
C:\Users\satya\AppData\Local\Programs\Python\Python37\; C:\Users\satya\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Python 3.7
The Actual Problem:
The same commands for installation given above work perfectly fine on my other Windows 10, but, for my Windows 8.1 it gives this error which has become a real PITA
Import Error: DLL load failed The specified module could not be found
When I import sklearn or import torch I get the exact same error. All the time.
Back Story:
I have searched almost all the related questions I could find on Stackoverflow and Github for 6+ hours to help me solve this problem. But, none of the answers have helped till now and some haven't had an "understandable" answer. Maybe, its just a small fix, but now, I am choosing to post a question on SO.
My Question Again:
Can someone please help out and try to explain what I am missing out here? I really want to fix this error for good(and want to be in a position to fix it if I encounter it again). An elaborate answer would really help understand easily.
Thank You!
Please check your python build number with the following command.
conda list python
Python 3.7.2 with build number h8c8aaf0_2 has a solved issue.
If this is the case, an update will do.
conda update python

How do I install the Pygraphics module

I am trying to download the Pygraphics module using Python 2.7.6 and have been heretofore unsuccessful. Below I detail the steps I have taken so far. Any help with this would be most appreciated.
First, I tried the typical install using pip
sudo pip install Pygraphics
When I try to import the module, I receive an error saying ImportError: No module named Pygraphics.
To test whether the module was installed I ran the following code: print sorted(["%s==%s" % (i.key, i.version) for i in pip.get_installed_distributions()]) which showed me all of my installed distributions.
This code returned the following list of all the distributions and clearly showed that Pygraphics is installed:
['altgraph==0.10.2', 'bdist-mpkg==0.5.0', 'bonjour-py==0.3', 'brewer2mpl==1.4', 'certifi==14.05.14', 'datetime==4.0.1', 'flask==0.10.1', 'ggplot==0.6.5', 'ipython==2.0.0-dev', 'itsdangerous==0.24', 'jdcal==1.0', 'jinja2==2.7.3', 'macholib==1.5.1', 'markupsafe==0.23', 'matplotlib==1.4.x', 'mock==1.0.1', 'modulegraph==0.10.4', 'nose==1.3.4', 'numpy==1.9.0.dev-297f54b', 'openpyxl==2.1.2', 'pandas==0.14.1', 'pandasql==0.6.1', 'patsy==0.3.0', 'pika==0.9.14', 'py2app==0.7.3', 'pygments==1.6', 'pygraphics==2.1']
After this, I tried using the GUI installer located on the following Pygrahpics install website. While going through the installer, I received an error message saying "PyGraphics requires System Python 2.7 to install" despite the fact that I have downloaded Python 2.7.6.
At this point I don't know what to do and was hoping someone who may have had a similar issue might be able to help me out.
Thank you for your time.
It looks like you've successfully install PyGraphics. Now import picture :)
