Hi all,

When I tried to install the latest version of carputils on macOS(12.4), while running python3 -m pip install . --user, the following error occurred:

Did you try to upgrade your pip and setuptools versions?

python3 -m pip install --upgrade pip 

python3 -m pip install --upgrade setuptools

Yes, I did, they are already requirements satisfied.  But the error is still existing.

I tried to completely remove the carputils folder and reinstall it, I have now gotten pass this error, but then another error occurred:

This is due to the fact that no wheel is existing yet for the Python package tables on arm64 Macs.
You have to install HDF5 on your system before being able to install tables.

Thank you so much! It works, I have been able to install it. However, while I try to run some examples (https://opencarp.org/documentation/examples/02_ep_tissue/01_basic_usage), it did not recognize that I have already installed carputils.

The command is:
python3 run.py --duration 20 --S1-strength 20. --S1-dur 15 --visualize

The error message is:
Traceback (most recent call last):
  File "/Users/abc/openCARP/external/experiments/tutorials/02_EP_tissue/01_basic_usage/run.py", line 155, in <module>
    from carputils import settings
ModuleNotFoundError: No module named 'carputils'

I have already modified the path in "settings.yaml" to:
CARP_EXE_DIR:
    CPU: /Users/abc/openCARP/_build/bin
# Other paths
MESHALYZER_DIR: /Users/abc/meshalyzer
# Path to the directory containing the openCARP source files
OPENCARP_SRC:   /Users/abc/openCARP/

The location where I installed the carputils is:
/Users/abc/openCARP/external/carputils/

If the installation of carputils with the following command run from the carputils directory

python3 -m pip install .

was successful, this is most likely an issue linked to your Python setup.

Are you sure that the Python executable you used for installing carputils is the same as the one used for running the example?

You can test if carputils is correctly installed by running

python3 -c "import carputils; print(carputils)"

If it prints the installation location, your carputils is successfully installed.

Alternatively, you can install caprutils following the installation instructions for developers:
https://opencarp.org/download/installation#development-installation
In this case, it is important to add carputils to your PATH and PYTHONPATH as explained in the instructions.

Personally, I have found that the most foolproof way to install carputils is through the developer instructions, as Marie suggested. Her suggestion on adding carputils to the PATH and PYTHONPATH variables is especially important.

If carputils is still not recognized, you could try putting your settings.yaml file under "$HOME/.config/carputils/", as suggested by Marie in a previous post: https://opencarp.org/q2a/305/installing-opencarp-and-carputils-on-linux-cluster

Several months ago I was struggling to link carputils and this was the final trick for me. However, things may have changed since the latest openCARP update.
