摆脱从语料库生成文档的错误

Question

I have a set of 1000 documents - encoded and compressed - in an lsm-db stored on my computer. When I try to decompress and decode, I get an error that says "Incorrect Header Check".

This is what I'm doing:

for key in my_lsm_db.keys():
    print key, zlib.decompress(my_lsm_db[key], zlib.MAX_WBITS|32).decode('utf-8')

After processing a few keys, the code throws an error. The error that I'm receiving is: error: Error -3 while decompressing data: incorrect header check

def remove_docs(my_lsm_db):
    for key in my_lsm_db.keys():
        ## write code that identifies an error when generated
        if <code that identifies document generating error>:
            del my_lsm_db[key]

Here's some information on Zlib and MAX_WBITS part of the code: Zlib Compression , Stack Overflow Answer for Zlib Automatic Header Detection

Answer 1

I tried using a try/except block around my code to overcome such error generating documents. It works for not just the above code, but other stuff also.

try:
    <code to execute>
except (<list of errors>) as e:
    print e
