Can't install psycopg2 successfully - postgresql

Requirement already satisfied: psycopg2 in/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages
This is the error message I get when I run
pip install psycopg2
in my terminal on Mac. But when I try to import it in python (simply using import psycopg2) in either version 2.7 or 3.6 of python I get an error message:
No module named 'psycopg2'
Any suggestions?

No module named 'azureml' >> !pip install azureml-core >> from azureml.core import Experiment

I am facing issues with Azure ML when i try to install the SDK with pip install azureml-core and then import azureml.core in my script. I do not understand how can it be possible to have this error assuming that the package installation is complete and confirmed by the terminal output with:
"Requirement already satisfied: azureml-core in
c:\python\python38\lib\site-packages"
I have installed azureml-core package with the terminal and in the script with !pip install azureml-core but still get this error...
SCRIPT:
!pip install azureml-core
from azureml.core import Experiment
print(azureml.core.VERSION)
OUTPUT:
1 #CONNNECTING TO AZURE INSTANCE
2 get_ipython().system('pip install azureml-core')
----> 3 from azureml.core import Experiment
4 print(azureml.core.VERSION)

ModuleNotFoundError: No module named 'azureml'
I am running the script locally with Python 3.8.10 on a Windows 10 last update and VSCode Insider.
My goal is to compute on an Azure instance without going through a remote because I would like to use my local fodlers.
ANSWER:
I have no idea why but it is working now.
Try to restart your VSCODE and your compute instance.
BTW, to check the version use :
import azureml
print(azureml.core.VERSION)

PyAudio import error : ImportError: DLL load failed: The specified module could not be found

I encountered an import problem by PyAudio.
I have a winodws 10, 64 bit, and use Anaconda and Spyder IDE with python 3.7.
I installed PyAudio in Ananconda, ran as administrator, with these commands :
cd
conda install -c conda-forge PyAudio
The installation ran without any problems.
I then restarted both Anaconda and SPYDER. PyAudio now shows up in Anaconda's list of installed packages.
When I try to import Pyaudio in Spyder (IPython console), I encounter this error message :
[1]: import pyaudio
Could not import the PyAudio C module '_portaudio'.
Traceback (most recent call last):
File "", line 1, in
import pyaudio
File "C:\ProgramData\Anaconda3\lib\site-packages\pyaudio.py", line 116, in
import _portaudio as pa
ImportError: DLL load failed: The specified module could not be found.
I tried to fix it by answers to similar ImportError message issued, while other users tried to import other packages like SKlearn ... , but with no success.
Your problem (and mine) are the same. The issue is, unfortunately, the version of python you're running (in tandem with your OS).
Check out this link:
https://people.csail.mit.edu/hubert/pyaudio/#:~:text=Note%3A%20As%20of%20this%20update,4.
Under the INSTALLATION section in the link for WINDOWS, PyAudio's latest version (0.2.11) is compatible with Python versions: 2.7, 3.4, 3.5, 3.6.
My current python is 3.8.5, so you (and I) could never use PyAudio unless they added compatibilities or we revert to an above python version.
I tried to install portaudio using
conda install portaudio
but it seems like it didn't work as it should be. However,
conda install -c anaconda portaudio
solved the problem.
see the official anaconda page

How to execute the right Python to import the installed tensorflow.transform package?

The version of my Python is 2.7.13.
I run the following in Jupyter Notebook.
Firstly, I installed the packages
%%bash
pip uninstall -y google-cloud-dataflow
pip install --upgrade --force tensorflow_transform==0.15.0 apache-beam[gcp]
Then,
%%bash
pip freeze | grep -e 'flow\|beam'
I can see that the package tensorflow-transform is installed.
apache-beam==2.19.0
tensorflow==2.1.0
tensorflow-datasets==1.2.0
tensorflow-estimator==2.1.0
tensorflow-hub==0.6.0
tensorflow-io==0.8.1
tensorflow-metadata==0.15.2
tensorflow-probability==0.8.0
tensorflow-serving-api==2.1.0
tensorflow-transform==0.15.0
However when I tried to import it, there are warning and error.
WARNING:tensorflow:From /usr/local/lib/python2.7/dist-packages/tensorflow_estimator/python/estimator/api/_v1/estimator/__init__.py:12: The name tf.estimator.inputs is deprecated. Please use tf.compat.v1.estimator.inputs instead.
ImportErrorTraceback (most recent call last)
<ipython-input-3-26a4792d0a76> in <module>()
1 import tensorflow as tf
----> 2 import tensorflow_transform as tft
3 import shutil
4 print(tf.__version__)
ImportError: No module named tensorflow_transform
After some investigation, I think I have some ideas of the problem.
I run this:
%%bash
pip show tensorflow_transform| grep Location
This is the output
Location: /home/jupyter/.local/lib/python3.5/site-packages
I tried to modify the $PATH by adding /home/jupyter/.local/lib/python3.5/site-packages to the beginning of $PATH. However, I still failed to import tensorflow_transform.
Based on the above and the following information, I think, when I ran the import command, it executes Python 2.7, not Python 3.5
import sys
print('\n'.join(sys.path))
/usr/lib/python2.7
/usr/lib/python2.7/plat-x86_64-linux-gnu
/usr/lib/python2.7/lib-tk
/usr/lib/python2.7/lib-old
/usr/lib/python2.7/lib-dynload
/usr/local/lib/python2.7/dist-packages
/usr/lib/python2.7/dist-packages
/usr/local/lib/python2.7/dist-packages/IPython/extensions
/home/jupyter/.ipython
Also,
import sys
sys.executable
'/usr/bin/python2'
I think the problem is tensorflow_transform package was installed in /home/jupyter/.local/lib/python3.5/site-packages. But when I run "Import", it goes to /usr/local/lib/python2.7/dist-packages to search for the package, rather than /home/jupyter/.local/lib/python3.5/site-packages, so even updating $PATH does not help. Am I right?
I tried to upgrade my python, but
%%bash
pip install upgrade python
Defaulting to user installation because normal site-packages is not writeable
Then, I added --user. It seems that the python is not really upgraded.
%%bash
pip install --user upgrade python
%%bash
python -V
Python 2.7.13
Any solution?
It seems to me that your jupyter notebook is not using the right python environment.
Perhaps, you installed the package under version 3.5,
but the Notebook uses the other one, thus it cannot find the library
You can pick the other interpreter by clicking on: Python(your version) - bottom left.
VS-Code - Select Python Environment 1
However you can do this also via:
CNTRL+SHIFT+P > Select Python Interpreter to start Jupyter Server
If that does not work make sure that the package you are trying to import is installed under the correct python environment.
If not open up a terminal, activate the environment and install it using:
pip install packagename
For example i did the same thing here: (Note: I'm using Anaconda)
installing tensorflow_transform
After a installation, you can import it in your code directly like this:
importing tensorflow_transform

throwing error while importing pymysql in Python code

I am working in machine in which python 3.6 is installed on windows 7
I cross validated pymysql installation.
pip3 install PyMySQL
Requirement already satisfied: PyMySQL in c:\users\
But still in the code, its throwing error while importing pymysql.
import pymysql
error detail:
ModuleNotFoundError: No module named 'pymysql'
You would need to check if the installation was done correctly
If you are not able to install it properly you could download the gzip or the wheel and do a pip install of that gzip or the wheel
Both are available here:
https://pypi.python.org/pypi/PyMySQL
