Hi,
I can not provide help about IDLE, but if you provide me with more information about your issue with polymer_cli.py, I would be happy to help.

I had created an environment and installed required dependencies.however,I was trying to run polymer on sentinel-2 images,there was error message.
runing code: python ./polymer_cli.py S2A_MSIL1C_20170402T024541_N0204_E132_T50RNV_20200727T095734.SAFE
I got the following information:
Traceback (most recent calll last):
File "/home/dingky/ . local/lib/python3.8/site- packages/polymer-v4.13/polymer_ cli.py", line 11, in <module>

Dear Ding,
You need to compile the program first, using the command "make".
More information can be found in the file README.md.
Cheers,
François

Dear François，
Thank you very much for your reply.I've completed to compile the program by
$ make ./polymer4.13/
.Unfortunately, this error still occurs. My Ubuntu system has two versions of python, is it related to this? Thanks for the answers and patience.
kind regards,
ding

I doubt your command has succeeded, because the command should be "make", in the directory containing the makefile, not "make ./polymer4.13/".

Hi François，
When I run command
the error code is as follows:
Code: Select all
auxdata/common/no2_clmatology.hdf:FAILED
md5sum:WARNING:1 computed checksum did NOT match
make:*** [makefile:47: auxdata_common] Error 1
After that, I executed the code：
Code: Select all
$ ./polymer_cli.py /home/ding/LC08_L1TP_121038_20160115_20170405_01_T1_MTL.txt /home/ding/outfile.hdf
and I received the following prompt:
Code: Select all
Traceback (most recent call last):
File "./polymer_cli.py", line 34, in <module>
run_atm_corr(Level1(args.input_file),
File "/home/ding/polymer-v4.13/polymer/level1.py", line 36, in __init__
self.autodetect()
File "/home/ding/polymer-v4.13/polymer/level1.py", line 61, in autodetect
raise Exception('Unable to detect sensor for file "{}"'.format(b))
Exception: Unable to detect sensor for file "LC08_L1TP_121038_20160115_20170405_01_T1_MTL.txt
what should I do and how do I deal with landsat-OLI data?
Thanks！

Hi,
It seems that the download of "auxdata/common/no2_climatology.hdf" has failed, could you try to remove this file and try again ?
By the way, there was a letter "i" missing in the filename you mentioned.
Concerning the processing of Landsat8 files :
* You need to provide a directory name, not a txt file. e.g. "LC80140282017275LGN00/"
* The autodetection of Landsat8 files is currently not implemented. I have made a quick modification of level1.py so that it should work. Please see the file level1.py, zipped and attached here.
Cheers,
François
