IE 4000 iox docker python pip doesn't work

Hi All,

I'm trying to implement a python application with docker in IE 4000 but when i run the command "pip install" to install a library in the iox-app its return this error:

/ # pip install pymodbus
Traceback (most recent call last):
File "/usr/bin/pip", line 9, in <module>
load_entry_point('pip==1.3.1', 'console_scripts', 'pip')()

ValueError: math domain error

I used  this cisco docker image for IE 4000:

devhub-docker.cisco.com/iox-docker/ie4k/base-rootfs:latest

 

are there any limitations concerning the implementation of pytohn on IE 4000 with this image?

is there another way to install python library on IE 4000?

 

Best Regards

It is recommended to install the relates packages during your creating the Docker container instead of installing it in the IOx app. Please try it.

Hi,

I've already tried to install the python package with the Dockerfile but docker return the same error and the container is not created.

 

This is the error returned

And this is the Dockerfile

 

FROM devhub-docker.cisco.com/iox-docker/ie4k/base-rootfs:latest

RUN opkg update && opkg install python
RUN opkg install python-pip
RUN pip install pymodbus

COPY poll-temperature.py /usr/bin/poll-temperature.py
RUN chmod 777 /usr/bin/poll-temperature.py

CMD /usr/bin/poll-temperature.py
