Hi ,

I have a script Python to read the Hierarchical from a format. First I extract this format with the library and after try to read the folder. In Pycharm is works:

result = Format [subfolder]

My question is: how can I do this structure in PythonCaller? I did try without success:

feature.setAttribute('Format[subfolder]',result)

 

Thanks,

Danilo

I cannot understand what you intend to achieve with this code.

feature.setAttribute('Formattsubfolder]',result)
If the 'feature' is an instance of fmeobjects.FMEFeature class, the code above performs to assign the value contained by a variable called 'result' to a feature attribute named 'Format subfolder]'.

Is it actually your intention? If so, what value does the variable 'result' contain, and how did you create the value in the script?

Hi @takashi

 

My example is read Hierarchical from a file :

Format = Brasilia.dat

Subfolder = /Month / Day ( Hierarchical from Brasilia.dat )

How can I read this structure in PythonCaller, instead in PyCharm it works :

result = Format subfolder]

Thanks your help

I don't know what the Hierarchical is, but the same codes should also work with a PythonCaller, if those work as expected with PyCharm debugger. Of course, you have to import the same module(s) that you are using in the source tested with PyCharm.

Hi @takashi

 

My code is:

 

def processFeature(feature):

 with h5py.File(Format,'r') as f:

	feature.setAttribute('fwsubfolder]',result) 
But the attribute result doenst show nothing. 

 

 

Thanks,

Looks like you intend to retrieve a group called 'subfolder' recorded in an HDF5 file using the 'h5py' module.

 

Assuming that the input feature has an attribute called "_hdf5filepath" storing file path to the source HDF5 file which contains a group named 'subfolder', this script retrieves the content of 'subfolder' group and saves it as a string value into a new attribute called "fÂsubfolder]".

 

import h5py
def processFeature(feature):
    Format = feature.getAttribute('_hdf5filepath')
    with h5py.File(Format, 'r') as f:
        group = fu'subfolder']
        feature.setAttribute('f(sobfolder]', '%s' % group) 
Since FME Desktop doesn't bundle the 'h5py' module by default, you have to install the package to your FME Desktop.
