Hi ModalAI Team,

I am creating Python scripts for ROS and within docker-kinetic on VOXL m500 

I have a few questions.

I am installing some python packages such as pandas, opcua etc.  I am installing them in roskinetic directory with following command:

python2.7 -m pip install pandas

Some packages were installed and worked just fine but I cannot install pandas. It gives the following error:

![5d819959-6707-40f9-a0b0-ca134b36f5c0-image.png](https://forum.modalai.com/assets/uploads/files/1618404646764-5d819959-6707-40f9-a0b0-ca134b36f5c0-image.png) 

I searched on the internet and it seems like its a problem with Python version.

**1)** At this point, what would you recommend to fix it?

**2)** I would like confirm if i am installing to the right place (roskinetic directory in docker)

**3)** After I power off and on, the Python packages, I installed, goes away and I need to install again. So, Should I run "docker commit" to save? or what am I doing wrong?

I am quite new to the Docker system, I would be so happy to get any help in this topic.

thank you in advance!

You should build up your Docker images with a Dockerfile and 'docker build'. However, if you make changes in the container that you want to keep then, yes, you can use 'docker commit'. There is a lot of good documentation on the Docker site about all of this.
