Python 3x
An Oracle Instant Client version 11g or higher. Refer to download the instant client version to this link

python -m pip install cx_Oracle --upgrade pip
It will install the cx_Oracle package for Python on Windows, and you will get the messages as shown below.

Found existing installation: pip 10.0.1
Uninstalling pip-10.0.1:
Successfully uninstalled pip-10.0.1
Successfully installed pip-18.0
Important if you have more than one version of Python, use the one associated to Jupyter notebook.
You need to import the package first:
pip install cx-Oracle
In simple words for anaconda users
while installing the package use small case letters source
conda install -c conda-forge cx_oracle
now while importing the package use init cap as
import cx_Oracle

I need to save my new sequential model but when I use the model.save(filename),it shows error like save_model requires hp5y.I tried installing h5py in conda by 'conda install -c anaconda h5py'command. And I also installed cython,but then the error exists .what should I do?
one should include the package in pycharm project interpreter after being downloaded in the conda environment.
I have a venv with the following details:
python 3.6
TensorFlow 2.0.0
I tried to install tensorflow-addons using the following:
pip install -q --no-deps tensorflow-addons~=0.6
But then I keep receiving the following error:
Could not find a version that satisfies the requirement tensorflow-addons~=0.6 (from versions: )
No matching distribution found for tensorflow-addons~=0.6
You are using pip version 18.0, however version 19.3.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
I also tried other versions of tensorflow-addons, e. g., 0.4.0, 0.5.0, ..., but it did not work out.
I came across this problem two times and each time I had to solve the problem with a different solution.
1. Solution:
Upgrade pip/pip3 by using the following command.
python3 -m pip install --upgrade pip
Select appropriate version of the tensorflow-addons using the
following link
https://github.com/tensorflow/addons#python-op-compatibility-matrix
Install using the following command
pip install tensorflow-addons==version
2. Solution:
go to https://pypi.org/project/tensorflow-addons/#history
click on appropriate version
click on "Download files" on menu to the left
click on a .whl file that matches your system
requirements/specifications
go to the directory where you download the .whl file and run the
following
pip install tensorflow_addons-name.whl
The problem appears to have been related to installing on Windows platforms in the earlier versions of tensorflow-addons. As of time of updating this comment this issue should disappear completely.
In fact the developers state it has been solved, as it is shown here:
FYI stable release for windows is out. pip install tensorflow-addons
https://github.com/tensorflow/addons/issues/173#issuecomment-573106184
At your command prompt, simply specify the version you want to install.
For me, my python version is 3.7.4 and Tensorflow version is 2.2.0
Therefore, the tensorflow-addons version that matches my python and tensorflow version is 0.10.0
pip install tensorflow-addons==0.10.0
Is it possible to install pandas without installing pip or Is there any other way to use pandas without installing pip.
Thanks in advance.
pip is a package management system used to install and manage software packages written in Python. Many packages can be found in the default source for packages and their dependencies
here is the another way:
Download and unzip the current pandapower distribution to your local hard drive.
Open a command prompt (e.g. Start–>cmd on Windows) and navigate to the folder that contains the setup.py file with the command cd
cd %path_to_pandapower%\pandapower-x.x.x\
Install pandapower by running
python setup.py install
You can get pandas installed using the Anaconda distribution, which includes the Anaconda prompt. After you open an anaconda prompt, you can run the following command:
conda install pandas
which will install the latest version of pandas, or:
conda install pandas=0.20.3
to get a specific version of the package. Another way to do it is to install it with Miniconda, which allows you to avoid downloading the Anaconda installer and hundreds of other packages. More information can be found here: https://pandas.pydata.org/pandas-docs/version/0.23.4/install.html
I can install other packages, but can't install Scrapy. I get the following errors:
warning: build_py: byte-compiling is disabled, skipping.
running build_ext
building 'lxml.etree' extension
error: Microsoft Visual C++ 10.0 is required (Unable to find vcvarsall.bat).
However, C++ is installed, which I installed numerous of times. I have x86 and 64 bit installations (not sure if it's 10.0) but I have 2013-2017 versions installed.
Please upgrade your pip by following command.
python -m pip install --upgrade pip
Then install Scrapy by following command.
pip install Scrapy
download latest twisted package and install with pip.
https://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted
after that install scrapy
In my case, I found that pywin32 was not installed...
So I did
download the latest Twisted package from https://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted
You want to use the amd64 if you have Windows 64 (regardless if it's an Intel processor or not)
You can use any browser for the download and copy/paste the file into the project folder of your current pycharm project.
Then in pycharm type this:
pip install Twisted-20.3.0-cp39-cp39-win_amd64.whl
(assuming that your package was Twisted-20.3.0-cp39-cp39-win_amd64.whl)
then proceed with:
pip install Scrapy
I Installed pillow using brew, and when I try to repeat the isntallation I see it's there:
brew install Homebrew/python/pillow
Warning: pillow-2.7.0 already installed
But when I try to load it into a script I get an error:
ImportError: No module named Image
Any suggestions?
python usually looks for Pillow under normal site package installs. Here's what I would do to get a minimal Pillow setup where python should be guaranteed to see it:
sudo easy_install pip
pip install Pillow
I think it may also be possible to just do:
sudo easy_install Pillow
but pip is a bit more user friendly if you're planning on using more python scripts that might have dependencies.
Note: another issue you might be running into is if you're trying to use the Homebrew python but are ending up using the base OSX install of it instead. Make sure which python is showing you what you expect it to be.
