Bug with h52fil

[mattlebofsky]

Trying to convert a filterbank file to hdf5 at GB using blimpy 1.2.1 (though I tried 1.2.0 and 1.1.8). And I get this error:

h52fil /mnt_bls4/datax3/holding/spliced_blc0001020304050607_guppi_57708_17466_HIP19335_0003.gpuspec.0002.h5 -o /datax3/users/sci -n filfromf5.fil Traceback (most recent call last): File "/opt/pyve/eepy/bin/h52fil", line 11, in load_entry_point('blimpy==1.2.1', 'console_scripts', 'h52fil')() File "/opt/pyve/eepy/local/lib/python2.7/site-packages/blimpy-1.2.1-py2.7.egg/blimpy/h52fil.py", line 60, in cmd_tool make_fil_file(filename, out_dir = opts.out_dir, new_filename=opts.new_filename) File "/opt/pyve/eepy/local/lib/python2.7/site-packages/blimpy-1.2.1-py2.7.egg/blimpy/h52fil.py", line 41, in make_fil_file fil_file.write_to_fil(new_filename) File "/opt/pyve/eepy/local/lib/python2.7/site-packages/blimpy-1.2.1-py2.7.egg/blimpy/waterfall.py", line 227, in write_to_fil self.write_to_fil_light(filename_out) File "/opt/pyve/eepy/local/lib/python2.7/site-packages/blimpy-1.2.1-py2.7.egg/blimpy/waterfall.py", line 274, in write_to_fil_light fileh.write(generate_sigproc_header(self)) #generate_sigproc_header comes from sigproc.py File "/opt/pyve/eepy/local/lib/python2.7/site-packages/blimpy-1.2.1-py2.7.egg/blimpy/sigproc.py", line 375, in generate_sigproc_header header_string += to_sigproc_keyword(keyword, f.header[keyword]) File "/opt/pyve/eepy/local/lib/python2.7/site-packages/blimpy-1.2.1-py2.7.egg/blimpy/sigproc.py", line 350, in to_sigproc_keyword return np.int32(len(keyword)).tostring() + keyword + value_dtype(value).tostring() UnicodeDecodeError: 'ascii' codec can't decode byte 0xaa in position 4: ordinal not in range(128)

Not sure how to proceed... I was told to create this issue...

Hi Matt, does the file open with the siggproc header tool? Can you please point your me toward the data file causing it, or is it all filterbanks?

Seems to be all hdf5 files (I'm trying to convert h5 files back into filterbank). So the sigproc header tool isn't relevant. But watutil does work to display the header (i.e. watutil -i filename)

You can find a bunch of files to test in, say, bls5:/datax/holding

H'ok, I think this is fixed in my last set of changes. This was specifically related to Py2/Py3 compatibility (AGAIN). I also found a missing b in b'src_raj that was causing Py3 (and only Py3) to load the wrong Angle value to sigproc filterbank, converting hourangle into degrees. 🤕 🐍🐍🐍

Thanks Danny! I'm looking at all the changes and merging soon. A conversation when you are here: what about stop supporting python2 by the end of the year? (But not earlier!!)
