It seems that you may be mixing packages installed by your default system python and those installed by graalpython. By default graalpython installs into the same site-wide directory as CPython (~/.local/lib/python3.8/site-packages/).

The simplest way to fix this is to use venv, which GraalPython supports. For example:

$GRAALVM_HOME/bin/graalpython -m venv /path/to/my/new/venv
. /path/to/my/new/venv/bin/activate
python -c 'import platform; print(platform.python_implementation())'
# output: GraalVM
python -m ginstall install pandas
# to end the venv session:
deactivate
python -c 'import platform; print(platform.python_implementation())'
# output: CPython

Edit: GraalPy specific ginstall package is deprecated in favor of using vanilla pip just like on CPython: python -m pip install pandas should work on GraalPy.

I found that there are a lot of environment variables in ~/.bash_profile. I comment all of them and compile numpy/pandas successfully. By the way, how do I verify the settings of gcc/clang is correct? Anyway, thank you for your help.

#export CC=/usr/local/Cellar/gcc/10.1.0/bin/gcc-10
#export CXX=/usr/local/Cellar/gcc/10.1.0/bin/g++-10

#export CC=/usr/bin/clang
#export CXX=/usr/bin/clang++

#export C_INCLUDE_PATH=/usr/local/Cellar/libiomp/20150701/include/libiomp:$C_INCLUDE_PATH
#export CPLUS_INCLUDE_PATH=/usr/local/Cellar/libiomp/20150701/include/libiomp/:$CPLUS_INCLUDE_PATH
#export LIBRARY_PATH=/usr/local/Cellar/libiomp/20150701/lib:$LIBRARY_PATH
#export DYLD_LIBRARY_PATH=/usr/local/Cellar/libiomp/20150701/lib:$DYLD_LIBRARY_PATH

#export MPICXX=mpicxx
#export LDFLAGS="-pthread -lm"
#export CFLAGS="-Wall -O3 -msse2 -Wno-unknown-pragmas -funroll-loops -fopenmp"
