Problems with ReedSolomonError Exception handling

[dchutchings]

here's the relevant snippets of my code, which works fine with errors not exceeding RS capability

N, K = 255, 223
rsc = RSCodec(N-K, nsize=N)

for i in range(0,Npixels*N//K,N):
    try:
        rx_byte = np.append(rx_byte,np.uint8(rsc.decode(rx_enc[i:i+N])[0]))
    except ReedSolomonError:
        rx_byte = np.append(rx_byte,rx_enc[i:i+K])

I get

Traceback (most recent call last):

  File "  ", line 36, in <module>
    rx_byte = np.append(rx_byte,np.uint8(rsc.decode((rx_enc[i:i+N]))[0]))

  File "C:\ProgramData\Anaconda3\lib\site-packages\reedsolo.py", line 924, in decode
    rmes, recc, errata_pos = rs_correct_msg(chunk, nsym, fcr=self.fcr, generator=self.generator, erase_pos=e_pos, only_erasures=only_erasures)

  File "C:\ProgramData\Anaconda3\lib\site-packages\reedsolo.py", line 747, in rs_correct_msg
    err_pos = rs_find_errors(err_loc[::-1], len(msg_out), generator)

  File "C:\ProgramData\Anaconda3\lib\site-packages\reedsolo.py", line 693, in rs_find_errors
    raise ReedSolomonError("Too many (or few) errors found by Chien Search for the errata locator polynomial!")

ReedSolomonError: Too many (or few) errors found by Chien Search for the errata locator polynomial!

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

  File "  ", line 37, in <module>
    except ReedSolomonError:

NameError: name 'ReedSolomonError' is not defined

Hello, thank you for reporting the 2 bugs.

It's a bit difficult for me to debug with this few information. Could you please write the corrupted message raising this error, and the original uncorrupted message?

About your second error (ReedSolomonError is not defined), you first need to import the custom exception class with:

from reedsolo import ReedSolomonError

I have now added this info in the readme.
