Hello,
There may have been a temporary network issue. Could you have another try ?

Also, this forum is not quite appropriate for this kinds of issues, which are mostly unrelated with the Polymer software.
Regarding seadas installation, you may get quicker and more helpful responses on https://forum.earthdata.nasa.gov/

Dear Mengmeng,
<seadas-<version> is not a valid command, it should refer to the actual version you are installing.
Also, I've had feedback that there can be issues with running OCSSW from the command line in SeaDAS 8.0.0. In that case you may want to try version 7.x, which works fine.

This normalization can be disactivated by passing a value to the argument normalize . Please ...

Hello Tian,

To process S2 MSI at 10m, you can pass the argument resolution='10' to Level1_MSI :

Dear Mengmeng, polymer_cli.py is a minimalistic command line interface, and a first way to run the code. For more control I generally advise to use your own python script as shown in the examples. readme 2.3 gives you the possible inputs you can provide to Polymer. readme 2.4 explains how to create ...

Indeed, your file is a Level2 file. Polymer needs to be applied to a Level1 file. Please see section 2.3 of the readme.
A modis example is also provided in example.py with some custom parameters ; you should rather use default parameters as in the meris, msi and olci examples.
