I am meeting another problem:
Traceback (most recent call last):
File "train.py", line 48, in
adj_train, train_edges, val_edges, val_edges_false, test_edges, test_edges_false = mask_test_edges(adj)
File "build/bdist.linux-x86_64/egg/gae/preprocessing.py", line 99, in mask_test_edges
assert ~ismember(val_edges_false, edges_all)
AssertionError
from gae.
@chao92 I met the same problem: 'assert ~ismember(val_edges_false, edges_all) AssertionError', maybe is not uncommon. Do you resolve this matter?
from gae.
@yjyGo, @chao92 I know this is kind of late, but try and reduce the validation/test split. I did that and it worked for me.
I reduced it to 5%, because my graphs are kind of small. Not sure if this is the right thing to do.
I also tried with those asserts commented out. It still ran, but, again, that is probably not recommended/right to do
from gae.
@yjyGo @chao92 I have encountered the same problem. I found that the cause of this error is that false validation edges can be in the test edge set. However, the above assertion requires that false validation edges be in the whole edge set, including the test edge set. I think we can solve the problem if we also check that false validation edges are not in the test edge in generating them.
Code to reproduce (test.py
)
import sys
import numpy as np
import scipy
import scipy.sparse as sp
from gae import preprocessing
print(f"python: {sys.version}")
print(f"numpy: {np.__version__}")
print(f"scipy: {scipy.__version__}")
np.random.seed(4)
A = sp.csr_matrix(np.random.randint(0, 2, (10, 10)))
A = sp.triu(A, 1)
A = A + A.T
preprocessing.mask_test_edges(A)
