I already installed HDF5 to /usr/local/hdf5/ but I'm still getting the same error. I'm a new to Python so any help will be greatly appreciated.

Thank you.

Simply try this procedure to install netCDF4

1. install HDF5 from link

2. install netcdf4 from link

3. install netcdf4-python from link

You might need to set the HDF5_DIR environment variable to the location where you install HDF5; it's looking in the standard install paths and not finding the headers for HDF5 - hence at least one of your errors.

You can simply set it before calling pip:

HDF5_DIR=/usr/local/hdf5 pip install netCDF4

or export it and then call pip:

export HDF5_DIR=/usr/local/hdf5
pip install netCDF4
