Error on opening files from New Horizons MVIC data

[alemran042]

I have been trying to read images from New Horizons MVIC data on a Linux OS (Ubuntu 20.04.2 LTS). I tried both adding .img and .lbl file but neither worked. Below the error:

from planetaryimage import PDS3Image
image = PDS3Image.open('....\mvic_0299178092_0x536_sci_pl.img')

or

image = PDS3Image.open('....\mvic_0299178092_0x536_sci_pl.lbl')

----------------------------for img file--------------------------------

Nobody is actively maintaining this project anymore. I suggest that you try to read the data with pdr.
https://github.com/millionconcepts/pdr

If it doesn't work please file an issue there with the error output and the full URL to the data on the PDS, and I'll try to fix it.
