[Biopython-dev] [Biopython - Bug #3395] Biopython trie implementation can't load large data sets

[redmine at redmine.open-bio.org]

Issue #3395 has been updated by Peter Cock.


Can you try the same test case without gzip? i.e. Can you load /tmp/trie.dat rather than /tmp/trie.dat.gz?

Also I would try explicitly opening the files in binary mode.

P.S. Which OS, which version of Python, which version of Biopython?

Imagine I have Biopython trie:

from Bio import trie
import gzip

f = gzip.open('/tmp/trie.dat.gz', 'w')
tr = trie.trie()
#fill in the trie
trie.save(f, trie)

Now /tmp/trie.dat.gz is about 50MB. Let's try to read it:

from Bio import trie
import gzip

f = gzip.open('/tmp/trie.dat.gz', 'r')
tr = trie.load(f)

Unfortunately I'm getting meaningless error saying:
"loading failed for some reason"

Any hints?
