ImportError: No module named pandas

I am trying to write code in Python to fetch Twitter data, and I am not getting an error for twython. But I am getting an error for Pandas.

I have installed Pandas using pip install pandas. But I still get the following error. How can I fix it?

You're missing a few (not terribly clear) steps. Pandas is distributed through pip as a wheel, which means you need to do:

pip install wheel pip install pandas

You're probably going to run into other issues after this - it looks like you're installing on Windows which isn't the most friendly of targets for NumPy, SciPy, and Pandas. Alternatively, you could pickup a binary installer from here.

You also had an error installing NumPy. Like before, I recommend grabbing a binary installer for this, as it's not a simple process. However, you can resolve your current error by installing this package from Microsoft.

While it's completely possible to get a perfect environment setup on Windows, I have found the quality-of-life for a Python developer is vastly improved by setting up a Debian VM. Especially with the scientific packages, you will run into many cases like this.

I just had the problem and I kept installing and uninstalling. It turns out the problem happens when you're installing Pandas to a version of python and trying to run the program using another python version.

So to start off, run:

which python python --version which pip

make sure both are aligned, most probably, python is 2.7 and pip is working on 3.x or pip is coming from anaconda's python version which is highly likely to be 3.x as well

In case of python redirects to 2.7, and pip redirects to pip3, install pandas using pip install pandas and use python3 file_name.py to run the program.

I fixed the same problem with the below commands...

Type python on your terminal. If you see python version 2.x, then run these two commands to install Pandas:

sudo python -m pip install wheel

and

sudo python -m pip install pandas

Else if you see python version 3.x, then run these two commands to install Pandas:

sudo python3 -m pip install wheel

and

sudo python3 -m pip install pandas

Good Luck!

When I try to build the docker image zeppelin-highcharts, I find that the base image openjdk:8 also does not have pandas installed. I solved it with this steps.

curl --silent --show-error --retry 5 | python pip install pandas

I referred to What is the official “preferred” way to install pip and virtualenv systemwide?.

If you are on Ubuntu and use the builtin Python 3, you can just install it from the Ubuntu repos like so in a terminal:

sudo apt install python3-pandas

the above works on Ubuntu 20.04 LTS and be slightly different depending on your version.

If you are running Python version 3.9, Pandas won't work as of now. So install Python version 3.7 or below to mitigate this issue.

Or else if you want to stick with Python 3.9, try install Pandas by compiling the library.

Try this:

python -m pip install pandas

As of Dec 2020, I had the same issue when installing python v 3.8.6 via pyenv. So, I started by:

Installing pyenv via Homebrew, brew install pyenv
Install xz compiling package via brew install xz
pyenv install 3.8.6. Pick the required version
pyenv global 3.8.6. Make this version as global
python -m pip install -U pip to upgrade pip
pip install virtualenv

After that, I initialized my new env, installed Pandas via the pip command, and everything worked again. The Pandas version installed is 1.1.5 within my working project directory.

Note: If you have installed Python before xz, make sure to uninstall it first, otherwise the error might persist.

curl -o get-pip.py
python3 get-pip.py
sudo python3 -m pip install pandas

For me how it worked was, I had two executable versions of Python so on pip install it was installing in one version, but my executable path version was different so it failed.

Then I changed the path in sys's environment variable and installed in the executable version of Python and it was able to identify the package from site-packages.

For me this happened in pycharm when I opened another project folder up. Seem like since I installed pandas in a folder that was not accessible to the new project folder my computer could not find the pandas.

Python uses a scripts folder to store this in I believe.

I know when I use pip install it pulls from the python script folder, so what I did was make a folder called "everything python", the name doesn't matter, and put my script folder here. Then took the other folders for other projects and put them in there and use the "everything python" as the project I want to work on in pycharm.

This solved it for me.

If using python 3, using pip3 instead of pip

python 3: pip3 install pandas

This is for those who tired the above answers but still have issues. You should do the following:
