unable to open .hdr file

[BlcaKHat]

as the optional image argument to envi.open.

img = envi.open('EO1H1400432009124110PY.hdr', 'EO1H1400432009124110PY.hdr')
Unable to create memmap interface.

i am able to open .lan, .spc but when i am opening .hdr , it's giving error. I am new to it, please help.

It is not an error per se. It is just informing you that numpy was not able to create a memmap interface to the file, which will result it significantly slower performance.

What is the size of the file (and also the sizes of the files that opened successfully)? Are you on a 32 or 64-bit system?

i am on 64 bit system and i want to open an image generated by envy . with the help of python.
I want to open the image same as it open in envi. please suggest me some libraries which will help me.

In your original post, you have the header file passed as the argument to envi.open twice (both arguments end in ".HDR"). The second argument should be the name of the image data file, which should either have a different extension (e.g., ".img", ".ref") or no extension at all.

yeah, i fixed that but how do i plot it with the help of spectral library. I don't know more about. In documentation I didn't got anything.

[tboggs]

There are multiple examples in the online documentation and system requirements are detailed in the installation section.
