使用paddle 1.5分支，在CPU下运行PaddleDetection中的cascade模型，有如下报错： Traceback (most recent call last): File "tools/train.py", line 204, in main() File "tools/train.py", line 159, in main outs = exe.run(train_compile_program, fetch_list=train_values) File "/opt/_internal/cpython-2.7.11-ucs2/lib/python2.7/site-packages/paddle/fluid/executor.py", line 665, in run return_numpy=return_numpy) File "/opt/_internal/cpython-2.7.11-ucs2/lib/python2.7/site-packages/paddle/fluid/executor.py", line 527, in _run_parallel exe.run(fetch_var_names, fetch_var_name) paddle.fluid.core_avx.EnforceNotMet: Invoke operator distribute_fpn_proposals error.
