This question is related to python pandas

The answer is


It might be too late to answer this but I just had the problem and I kept installing and uninstalling, it turns out the 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

Incase 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.


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/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 dev is vastly improved by setting up a debian VM. Especially with the scientific packages, you will run into many cases like this.


For me how it worked is, I have two executable versions of python so on pip install it was installing in one version but my executable path version is 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


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!


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

  1. Installing pyenv via homebrew brew install pyenv
  2. Install xz compiling package via brew install xz
  3. pyenv install 3.8.6 pick the required version
  4. pyenv global 3.8.6 make this version as global
  5. python -m pip install -U pip to upgrade pip
  6. pip install virtualenv

After that, I initialized my new env, installed pandas via pip command, and everything worked again. The panda's version installed is 1.1.5 within my working project directory. I hope that might help!

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


When I try to build 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 https://bootstrap.pypa.io/get-pip.py | python
pip install pandas

If you are running python version 3.9 pandas wont 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
