I am using Google Colab to write some codes. I need to use scikits.audiolab. Even though the installation seems to be successful, I am not able to import it.
Does someone know why it happens and how can I solve?
scikits.audiolab is a very old package (the last release was in 2010) and it does not work with Python 3.
After switching to a Python 2 runtime (Runtime->Change runtime type and select Python 2), I was able to install it without the --local flag and import it:
!pip install scikits.audiolab
import scikits.audiolab

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:

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?
I have installed Python 3.10.6 and Pycharm community edition.
Everything was working until I tried to use numpy.
pip3 install numpy
import numpy as np
This is the error message:
pip3 install numpy
^^^^^^^
SyntaxError: invalid syntax
I also have tried to use pip install numpy and pip2 install numpy and pip3 install numpy scipy, but same error. Reinstalling both python and pycharm didn't help.
Ah, I understand your problem more specifically now. I also use PyCharm, and this same problem happened to me. It was very frustrating, and took me lots of reading to fix it.
PyCharm and other IDEs (integrated development environment) have something called 'run configurations' attached to each file you are working on. These run configurations basically specify which directory on the hard drive the file will use to read and execute your commands. The directory will contain the libraries you need to run your code.
They use these configurations to make it easy to quickly choose which directory (and which libraries) you want a certain file to use. You must specify these configurations in PyCharm for your specific file to run using Numpy. The great thing about PyCharm is that you can actually specify libraries you want to use within the IDE itself (and bypass having to specify a computer-native directory).
Here's How
Go to PyCharm Preferences
Expand the arrow that says 'Project: (your project name)'
Click on 'Python Interpreter'
Click the small '+' symbol
Type in 'numpy' to search for the library (package)
Click install package
Now try to run your file and it should be good to go!
Note that you must do this for each package you wish to use when accessing your file, and as you advance your programming knowledge it will be necessary to learn how to specify the directory you want PyCharm to run the Python Interpreter from. Since you are only using one library though, I think this solution should be fine for the time being.
You should install numpy with that command in your bash/zsh shell.
pip3 install numpy
the python script can then import it.
to test, run pip3 install numpy
then,
python to open a python shell.
and then you'll see
>>>
Type import numpy as np and be sure it imports. It should now.
It can be maddeningly confusing when first starting out with python and trying to figure out how to download libraries. Here are a few critical things I wish I understood before starting my Python journey, as well as the answer to your question.
Python is the language, and the files that support its functionality are located on the hard drive.
Libraries (like Numpy) can be thought of almost as interpreters (note that we are not using the computer definition of 'interpreter') and are stored alongside the Python files on the hard drive. They give Python more flexibility in terms of what it is able to do by increasing what commands Python is able to understand.
Once a library is downloaded, it must be imported to your Python script before you start writing library-specific commands. Importing a library tells Python: "Hey, I'm going to be writing some commands that you haven't seen before, but here is the library with the commands and what they want you to do in a way that you understand."
'pip' is Python's installer for these libraries.
Ex) I have a csv file that I want to read. I learn that Pandas has a csv reader function:
pandas.read_csv()
If I were to type this function in a script, Python would have no idea what I meant. But if I were to download Pandas, then import it into my script, Python would understand exactly what I'm saying.
How to Download Numpy
Assuming you are on Windows, open the terminal (command prompt) and run the command:
py -m pip install numpy
If you don't already have it, the terminal should have a few lines run and should end with something like 'numpy installed successfully'.
You can check to see if you have it by running the following command in your terminal:
py -m pip list
This command provides you with a list of all the downloaded libraries. You can check among them to make sure Numpy is downloaded.
Importing Libraries
Once you've downloaded the libraries you need, you need to import them into your script (the Python file where you are writing your code) in order for it to run properly. This is accomplished using the import command. One important thing to note is that you can import libraries and assign them a nickname using the as modifier.
Ex) Back to that csv file I want to read. I don't want to type 'pandas' in front of all the Pandas commands, so when I import it into the script I abbreviate it as 'pd':
import pandas as pd
pd.read_csv()
See the difference?
TL;DR for Your Scenario
Go to the terminal, and use the py -m pip list command to check if you have Numpy downloaded. If not, run the py -m pip install numpy command. Then go to your script with your actual python code, and import numpy with the import numpy command. Common Python practice is to import numpy as np, FYI.
Hope this clears things up.
It may say that you need to upgrade pip, which is fine, and it should give you a command to run that will upgrade pip to the newest version.
How to download "time" package for python 3.6. I was trying to install it for weeks but I always get the same error massage. Can someone explain me what am I doing wrong.
time is included in the standard library. All you need to do is import time. I would also highly recommend updating your Python version to a more recent version like 3.10.4.
It's included in python’s standard library, no reason to install or download. You can just import it like so:
import time
i am trying to use PyMouse plugin on windows 8.1 .
i used this code to import library :
from pymouse.windows import PyMouse
but this error shows :
from win32api import GetSystemMetrics
ImportError: No module named
'win32api'
where is the problem? i am not sure that i install the library fine ! can you show how to install it on windows ?
The win32api module is part of PyWin32, so you need to install that.
Meanwhile, you should be installing things with pip whenever possible. Some packages aren't pip-installable, or have incorrect requirements specs, but most packages, if you try to pip install them, will either automatically fetch their dependencies or complain that they're missing.
Also it looks like PyMouse's documentation is wrong, because it claims to only require ctypes (which comes with Python 2.6+), not PyWin32, on Windows. You may want to file a documentation bug with them.
However, it looks like the PyMouse you were using was abandoned at version 0.4 about 6 years ago. It was then picked up by someone else, but, as the README says, it was later merged into PyUserInput. So, you probably want to use that instead.
Note that PyUserInput correctly mentions the other dependencies in its README. It also checks them in its setup.py file. So hopefully, all you have to do is:
pip install PyUserInput
… and it will either pull in PyWin32 and pyHook, or complain that you have to go get them manually.
