outofculture / metaarray Goto Github PK

MetaArray.view was deprecated in the PyQtGraph source, presumably to better align with numpy.

Hi,

MetaArray cannot be installed with pi currently, because in setup.py it requires the package "hdf5" which is not available on pypi. I think this is a little mistake and instead of
install_requires=["numpy", "hdf5"],
it should have been:
install_requires=["numpy", "h5df"],

Can you fix this and publish a new metaarray release?

Thanks!

This particular issue has been a problem for several years, even when metaarray was part of pyqtgraph. I have manually patched this several times, but perhaps it is time for a proper solution.

Camera data (in acq4) may have values written with "L" appended to the integer. This causes a failure in readHDF5Meta, where the value string cannot be evaluated.

A simple solution to this is (lines 897-903 of init.py):

        if isinstance(val, str):  # strings need to be re-evaluated to their original types
            if val[-1] == 'L':  # strip trailing "long" 
                val = val[:-1]
            try:
                val = eval(val)
            except:
                raise Exception('Can not evaluate string: "%s"' % val)

A more robust solution might involve also capturing 'U', 'l' (lower case) or other characters that might be appended to a number. However, the only instance I have encountered in data stored by Acq4 is the 'L'.
