Issue setting up environment about coastsat

[kvos]

@huyquangt
I don't know what is causing that error, I was not able to reproduce it and line 207 of SDS_download.py doesn't seem to have an invalid syntax. I suggest you go into the /coastsat subfolder and delete the pycache folder. Then open spyder (within the coastsat env) and try to run example.py again.

Let me know how it goes,

Hi @kvos,

Sorry for a late reply & I have not sorted this out..

The error message only happens with Spyder on Windows (Spyder on Linux works fine). However, on windows, I can run this script using Command Prompt (e.g. python example.py). Therefore, I guess Spyder requires additional packages.

Any more suggestions?

@huyquangt, my guess would be that Spyder is using python2 instead of python3. Can you run the following commands in Spyder and let us know what you get?

>>> import sys
>>> print(sys.version)
3.7.3 (default, Apr 24 2019, 15:29:51) [MSC v.1915 64 bit (AMD64)]

It should be showing python version 3.x, rather than 2.x.

Hi @chrisleaman ,

my spyder is 3.7.3 actually.

I have reinstalled anaconda, then now example.py can run a halft way ( all files were succesfully downloaded and saved in 'reprocessed' folder), then another error message appears:

Can we check which versions of the packages you have installed? Make sure you have the coastsat environment activated (conda activate coastsat), then can you provide the output of conda list?

[huyquangtranaus]

Yes.. I did run conda activate coastsat and the conda list is attached.
conda_list.txt

[kvos]

hi @huyquangt , is this error still happening or you found a way around it?
I looked at your conda_list.txt file and you have a lot of packages in there that are not required for CoastSat, some of these may be conflicting with GDAL. I suggest you create a new environment with only the packages listed in environment.yml and try again. Let me know how it goes

[huyquangtranaus]

Hi @kvos,

sorry for a late reply as I was working on another task..

I have not solved this problem yet. Attached is the list of packages I am currently having after activating coastsat program.

Another error message comes out when I specify several satellite at the same time below is also attached.

Traceback (most recent call last):

print('\r%d%%' % (int(((i+1)/n_img)*100)), end='')

UnboundLocalError: local variable 'i' referenced before assignment

conda_list_COASTSAT.txt

[huyquangtranaus]

For example,

For a test, I specify:

#date range

dates = ['2012-04-01', '2012-05-01']

# Sat missions

sat_list = ['L5', 'L7', 'L8', 'S2']

The error message is:

File "C:\CoastSat-master\coastsat\SDS_download.py", line 207, in retrieve_images
print('\r%d%%' % (int(((i+1)/n_img)*100)), end='')

UnboundLocalError: local variable 'i' referenced before assignment

[kvos]

I don't really know what may be going wrong here as the line that you mention is correct and is sitting inside a loop for i in range(n_img) so i is always defined. I saw that your coastsat environment still has additional packages that are not needed, since those may be causing conflicts you could run conda clean -all and then re-install the CoastSat environment.

[huyquangtranaus]

Ok... it is solved....thanks kvos..

[kvos]

ok, just out of curiosity, what solved the problem? re-installing the environment?

[huyquangtranaus]

Yes @kvos I deleted everything and downloaded the current codes in GitHub and run new environment.

[kvos]

perfect, I will close the issue then.
cheers,
Kilian
