Error when using python 3.9.6

[GuanqiDong92]

I want to install cfspopcon on Mac, but it seems to have failed to start well with the example. Do you have a similar problem?

@GuanqiDong92 Could you post some more details about how one can reproduce this issue?
E.g. how was your python environment setup, and what steps did you take to install cfspopcon

@GuanqiDong92 it looks like you haven't run radas yet. https://cfspopcon.readthedocs.io/en/latest/doc_sources/Usage.html

hi @hassec , the python version and the environment are as follows

As for the installation of cfspopcon, I just use "pip install cfspopcon" following the instruction in https://cfspopcon.readthedocs.io/en/latest/doc_sources/Usage.html as @tbody-cfs commented.

@GuanqiDong92

Can you try running the radas command again with the --verbose flag:

radas --verbose -d ./radas_dir

If that crashes again and drops you into the debugger (ipdb), could you type bt, hit enter and post the resulting backtrace here?

@hassec , here is the result

Hi @GuanqiDong92. Could you try rm -rf ./radas_dir and then rerun the radas --verbose -d ./radas_dir command? This should take about 10-15 mins — it's important to not kill the process while this runs.

It looks like you're missing some of the files needed for the ADAS reader.

Hi @tbody-cfs , it does not work for me.....

[hassec]

Thanks @GuanqiDong92. I can reproduce the problem when using python 3.9.6 like you.
The reason for the error is that radas is using:

shutil.unpack_archive(output_filename, output_folder, filter="data")

But passing filter='data' is a security patch that only is available to python 3.9.17 and later.

So the easiest workaround would probably be to use a newer python version. We'll fix this on radas, but likely just by requiring a newer python version as passing filter='data' has security benefits.

@GuanqiDong92 I've opened #14 as a potential fix. You're welcome to try run that version of radas before we get it onto PyPi, following the instructions below

cd .. #change to some folder where you want to install radas
git clone [email protected]:cfs-energy/radas.git
cd radas
git checkout patch_shutil_for_py39
poetry install
poetry run radas --verbose
cd ../cfspopcon #change back to the cfspopcon repository
cp -r ../radas/radas_dir .
poetry run popcon example_cases/SPARC_PRD --show

[hassec]

A new version of cfspopcon has been released: https://pypi.org/project/cfspopcon/6.0.1/ which requires the fixed version of radas.
Closing this issue, but if you run in any more problems, please feel free to reopen the issue.

git clone [email protected]:cfs-energy/radas.git

hi @tbody-cfs , when I try "poetry run radas", it comes to the following error..

I googled it, it seems clang/gcc have conflicts. But I don't know how to fix it, could you please help?

[tbody-cfs]

How did you install gfortran? I'd suggest using brew install gcc (https://fortran-lang.org/learn/os_setup/install_gfortran/#homebrew)

If you've already done that, can you paste here your which gfortran?

please forget my last information. After I reinstalled gcc and Python, I redone all the previous steps. However,

but I try install importlib-metadata, it did not work...

Have you run poetry install in the cfspopcon folder?

If there are issues in cfspopcon, please re-open an issue in that repository. Also, for the future, please copy-paste the error message instead of screenshots, since this makes it easier for others to search and find related issues.

@tbody-cfs thank you. it works now after I run poetry install in the cfspopcon folder.
