too many indices for array

[khadkarajesh]

I was trying to run the code on amazon-book data for few epoch. I got the error mentioned below.

Used Command

python LightGCN.py --dataset amazon-book --regs \[1e-4\] --embed_size 64 --layer_size \[64,64,64\] --lr 0.001 --batch_size 8192 --epoch 10

Error

Traceback (most recent call last):
  File "/Users/rajeshkhadka/PycharmProjects/LightGCN_v2/LightGCN.py", line 714, in <module>
    best_rec_0 = max(recs[:, 0])
IndexError: too many indices for array: array is 1-dimensional, but 2 were indexed

I find the reason
just because when the epoch<20, it will not excute test method,so rec is []
