Got an error when runnin "UFS_IC_generator.py" (CCPP-SCM v5.0.0)

[wzzheng90]

Hi,

Within the scm/etc/script, I tried "UFS_IC_generator.py" script to generate the example UFS Atmosphere initial condition case input file.

I got an error when I run "UFS_IC_generator.py" to create ICs on NOAA's Hera HPC. For example, I just try a sample case as follows:

./UFS_IC_generator.py -l 261.51 38.2 -d 201610030000 -i ../../data/raw_case_input/FV3_C96_example_ICs -g ../../data/raw_case_input/FV3_C96_example_ICs -n fv3_model_point_noah -oc

The error message shows as follows:
File "./UFS_IC_generator.py", line 2045
print 'Tile found: {0}'.format(tile)
^
SyntaxError: invalid syntax

BTW, the shapely python package is installed on Hera. Is it still a problem related to python version?

Thanks,

Weizhong

@wzzheng90 I can replicate this error on Hera. It may be that the setup Hera setup script needs updating. FWIW, this script works on Cheyenne. I will take a look this afternoon.

In the meantime you can use this environment to run the script.
conda create --name py27env --clone /scratch2/BMC/ome/Dustin.Swales/libs/miniconda3/envs/py27
conda activate py27env

@dustinswales : Many thanks!!

   I tried to use this environment according to your suggestion. Then, I run the script.  Another problem happens as follows:

===================================
Traceback (most recent call last):
File "./UFS_IC_generator.py", line 7, in
from netCDF4 import Dataset
ImportError: No module named netCDF4

Line 7 in "UFS_IC_generator.py":          from netCDF4 import Dataset

How to fix this problem?

@wzzheng90
I think if you repeat this process, but for py37_scm, it should work.

[dustinswales]

@wzzheng90
Sorry, I just restored my py27 environment. You should be able to clone this as before and it "should" work.

[wzzheng90]

@dustinswales Really appreciate it. It's working now. Thanks again.

[dustinswales]

Make sure that you are using the correct python.

:

[dustinswales]

[Dustin.Swales@hfe09 scripts]$ where python
/usr/bin/python
[Dustin.Swales@hfe09 scripts]$ conda activate py27env
(py27env) [Dustin.Swales@hfe09 scripts]$ where python
/scratch2/BMC/ome/Dustin.Swales/libs/miniconda3/envs/py27env/bin/python
/usr/bin/python

You should see a second python that appears when you activate py27env?

[wzzheng90]

I tried again. It does not see a second python:

%where python
/usr/bin/python

%conda activate py27env
%where python
/usr/bin/python

[wzzheng90]

I tried it again. I did not see the second python, but see (py27env) environment?

zeuse /scratch2/NCEPDEV/land/Weizhong.Zheng/noscrub 257 %where python
/usr/bin/python
zeuse /scratch2/NCEPDEV/land/Weizhong.Zheng/noscrub 258 %conda activate py27env
(py27env) zeuse /scratch2/NCEPDEV/land/Weizhong.Zheng/noscrub 259 %where python
/usr/bin/python
(py27env) zeuse /scratch2/NCEPDEV/land/Weizhong.Zheng/noscrub 260 %

[wzzheng90]

@dustinswales It works now if "/scratch2/BMC/ome/Dustin.Swales/libs/miniconda3/envs/py27env/bin/python" is used before UFS_IC_generator.py, although I can not see the second python if I type "where python".

Thank you very much for your kind help !!

[dustinswales]

Great that it's working!

[wzzheng90]

@dustinswales I use your "/scratch2/BMC/ome/Dustin.Swales/libs/miniconda3/envs/py27env/bin/python" for UFS_IC_generator.py.
However, it looks like "py27env" was removed, and you updated something. Could you please inform me how to update? Thanks.

In the past, I used "conda activate py27env".

[wzzheng90]

@dustinswales I did as follows but it still got a problem.

% conda create --name py37_scmenv --clone /scratch2/BMC/ome/Dustin.Swales/libs/miniconda3/envs/py37_scm
% conda activate py37_scmenv
%where python
/home/Weizhong.Zheng/.conda/envs/py37_scmenv/bin/python
/usr/bin/python

% /home/Weizhong.Zheng/.conda/envs/py37_scmenv/bin/python ./UFS_IC_generator.py .......

File "./UFS_IC_generator.py", line 2045
print 'Tile found: {0}'.format(tile)
^
SyntaxError: invalid syntax

It looks like I still not use the correct python version?

Thanks.

[wzzheng90]

@dustinswales I tried "py37_scm" again but still not working. Do you still keep "py27env" on your directory? Thanks.

[wzzheng90]

Really appreciate it. It's working now.

Hello,

I am having the same problem with the UFS_IC_generator.py (as shown by wwzhen90 in the first part of this question), but in Cheyenne. There is any specific conda environment that I should use at Cheyenne? or there is any updated version of this script (in Python 3.0+)?

Regards

Christian

@christianbsch This issue is fixed in the main branch. Please refer to the documentation (ccpp-scm/scm/doc/TechGuide/main.pdf) in section 5.5 for setting up the environment and running the script.
