Install SWIG as below.
$ wget https://github.com/swig/swig/archive/refs/tags/v4.0.2.tar.gz
$ tar xvfz v4.0.2.tar.gz
$ cd swig-4.0.2
$ ./autogen.sh
$ ./configure
$ make
$ sudo make install
Note: If CentOS, you might need to install pcre in advance.
$ sudo yum install pcre2-devel.x86_64
Install GridDB Server and C Client. (Note: If you build them from source code, please use GCC 4.8.5.)
Set CPATH and LIBRARY_PATH.
export CPATH=$CPATH:<Python header file directory path>
export LIBRARY_PATH=$LIBRARY_PATH:<C client library file directory path>
Install Pandas and Numpy as below:
$ python3 -m pip install numpy
$ python3 -m pip install pandas
1. Execute the command on project directory.
$ make
2. Set the PYTHONPATH variable for griddb Python module files.
$ export PYTHONPATH=$PYTHONPATH:<installed directory path>
3. Import griddb_python in Python.
GridDB Server need to be started in advance.
1. Set LD_LIBRARY_PATH
$ export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:<C client library file directory path>
2. The command to run sample
$ python3 sample/sample1.py <GridDB notification address> <GridDB notification port>
<GridDB cluster name> <GridDB user> <GridDB password>
-->Person: name=name02 status=False count=2 lob=[65, 66, 67, 68, 69, 70, 71, 72, 73, 74]
Please refer to Cmake Build Guide
Install the MSI package, the package is extracted into C:/Program Files/griddb/Python Client/X.X.X folder.
<PATH_TO>/python.exe sample1.py <GridDB notification address> <GridDB notification port>
<GridDB cluster name> <GridDB user> <GridDB password>
Note: X.X.X is the software version.
Install SWIG as below.
$ wget https://github.com/swig/swig/archive/refs/tags/v4.0.2.tar.gz
$ tar xvfz v4.0.2.tar.gz
$ cd swig-4.0.2
$ ./autogen.sh
$ ./configure
$ make
$ sudo make install
Note: If MacOS, you might need to install pcre in advance.
$ brew install pcre
Install GridDB Server and C Client. (Note: If you build them from source code, please use clang 11.0.0)
Set CPATH and LIBRARY_PATH.
export CPATH=$CPATH:<Python header file directory path>
export LIBRARY_PATH=$LIBRARY_PATH:<C client library file directory path>
Install Pandas and Numpy as below:
$ python3 -m pip install numpy
$ python3 -m pip install pandas
1. Execute the command on project directory.
$ make
2. Set the PYTHONPATH variable for griddb Python module files.
$ export PYTHONPATH=$PYTHONPATH:<installed directory path>
3. Import griddb_python in Python.
GridDB Server need to be started in advance.
1. Set DYLD_LIBRARY_PATH
export DYLD_LIBRARY_PATH=${DYLD_LIBRARY_PATH}:<C client library file directory path>
2. The command to run sample
$ python3 sample/sample1.py <GridDB notification address> <GridDB notification port>
<GridDB cluster name> <GridDB user> <GridDB password>
-->Person: name=name02 status=False count=2 lob=[65, 66, 67, 68, 69, 70, 71, 72, 73, 74]
