I tried installing pandas on my windows 8 via the CMD but I get n error like
"python setup-py egg_info" failed: with error code 1 in C:\users\username\APP Data\Local\Temp\pip-build-cbdsd3_x\pandas
Any clue on how I can resolve this? Thanks
First you need to visit : http://www.lfd.uci.edu/~gohlke/pythonlibs/
then download numpy+mkl wheel file. Then you can install pandas
Try to install Anaconda for Windows. It comes with a lot of libraries. You can refer this for a detailed list of packages installed and instructions on how to install external packages.
I was having trouble installing SciPy, Pandas and a few other libraries. Instead of solving issues for every library, I think installing Anaconda is a far better option. Plus, it comes with Spyder(IDE) and Jupyter notebook and a lot more other tools.

I'm using Python 3.7 and I recently upgraded to Spyder 4.2.0 from Spyder 4.1.5. Now when I run my code (which was working fine before) I get the following error:
ImportError: Missing optional dependency 'xlrd'. Install xlrd >= 1.0.0 for Excel support Use pip or conda to install xlrd.
So apparently Spyder thinks 'xlrd' ('Excel Reader'?) is not installed. So I went to the Anaconda prompt and tried pip install xlrd, but it replied with
Requirement already satisfied: xlrd in c:\users\michael\anaconda3\lib\site-packages (2.0.1)
I tried uninstalling and reinstalling xlrd anyways, using pip, but it didn't change anything. How do I resolve this error?
Also, I'm not sure if this matters or not, but I originally installed Spyder via Anaconda, whereas now I just downloaded Spyder 4.2.0 by itself, through this link: https://github.com/spyder-ide/spyder/releases.
Also, on the linked github page, it says: "If you are new to Python or the Scientific Python ecosystem, we strongly recommend you to install and use Anaconda. It comes with Spyder and all its dependencies, along with the most important Python scientific libraries (i.e. Numpy, Pandas, Matplotlib, IPython, etc) in a single, easy to use environment."
I had at first assumed this was meant for people downloading Python/Anaconda for the very first time, but now I'm thinking this applies to a semi newbie at Python such as me? As someone who is not very familiar with how packages and dependencies work, should I be downloading Anaconda every time I want to update Python or Spyder?
Apologies for the (probably) silly newbie question...
This sounds like you needed to re-start Spyder for it to pick up the package you installed.
However, as the author of xlrd, I would suggest you do the following:
Stop Spyder
conda install openpyxl
Start Spyder.
Change your pandas code to be pd.read_excel(..., engine='openpxyl')
I'm trying to install pandas in my windows 10 64bit computer. I already installed python 3.8.0 from the follwing link.
https://www.python.org/downloads/windows/
I tried to install pandas by pip install pandas command.
But I couldn't install pandas due to the following error. Can someone help me to solve this error?
When I tried to install numpy by pip install numpy I'm getting the following error.
Based on the Traceback calls, install the Microsoft Visual C++, followed by the installation of NumPy and Pandas library.
You or others facing the same problem can also proceed by installing Anaconda which has all the built-in libraries in it.
I have been successfully using PyCharm for my python work.All the packages can be easily installed by going to settings and then project interpreter but tensorflow installation is showing error.In suggestions it asked me to upgrade pip module.But even after that it shows error with following message:
" Could not find a version that satisfies the requirement tensorflow (from versions: ) No matching distribution found for tensorflow"
I am able to install all other packages but error is with tensorflow only.I am using windows.
Please run pip install tensorflow in command line and post the output here. Tensorflow can be installed on Windows but the process is often annoying.
You could also tried anaconda. It is has very nice UI and you could switch between different version.
I'm trying to install graphviz on windows 10 (Python 3.6). I went through multiple documentations but nothing seems to work. I tried to run below commands which were explained in the various documentations but it didn't work.
install -c anaconda graphviz
conda install -c anaconda graphviz #I tried these commands in python console
I get below error:
Syntax Error : invalid syntax
Can anyone tell me the exact procedure of installing graphviz on windows?
pip install graphviz didn't work for me. The library could be imported, but when I tried to open real-world examples, it crashed because of missed dependencies. (I actually found this topic while trying to solve those crashes lol).
The following two commands solved all my problems:
conda install graphviz
conda install python-graphviz
I am now able to replicate all the (graphviz) plots presented in this well-known Machine Learning repository:
https://github.com/quark0/darts
PS. Perhaps executing only the second command (alone) is enough (conda install python-graphviz), I am not 100% sure. I only know that conda install graphviz doesn't work alone for Python.
You should first install graphviz. http://www.graphviz.org/download/
After installing it and adding to path installing the python bindings should be straight forward.
pip install graphviz

I am using python 3.5 and I am trying to install NumPy but when I try to install from command prompt using command: pip install numpy
I get a whole lot of errors. The main error though seems to be at the end: error: Unable to find vcvarsall.bat
I have also tried downloading the numpy binaries from http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy and installing using command: pip install numpy-1.10.4+mkl-cp35-cp35m-win_amd64.whl
But I get an error that says: numpy-1.10.4+mkl-cp35-cp35m-win_amd64.whl is not a supported wheel on this platform.
Then I found a numpy-1.10.2-win32-superpack-python3.4.exe file here https://sourceforge.net/projects/numpy/files/NumPy/1.10.2/ but when I try to run that I get an error that I require Python version 3.4.
I looked and cannot find an installer for python 3.5.exe, do I need to uninstall python 3.5 and install 3.4 instead? Or is there anyway to install numpy for Python 3.5?
I am using Windows 10/64 bit.
An easy way to obtain numpy, scipy, pandas, ... is to install anaconda.
Anaconda will automatically download and install the latest modules.

I hope this will help you along.
