【有偿求助】tensorflow1.14代码报错

具体哪一行呢？光看这个判断不出来

tensorflow 我熟 【 在 yifei2017 的大作中提到: 】 :推荐系统相关 :TypeError: Fetch argument None has invalid type <class 'NoneType'> :谷歌以及stackoverflow等平台都找过原因，还是不太行 :在线等~~~[ema1]

私信看看

代码贴出来呗

不好意思，报错情况是这样的，涉及到的代码有点多且乱，不太方便贴，报错的具体行是函数调用，也不能直观看出来出错的地方 Traceback (most recent call last): File "MF/train_new_api.py", line 1667, in <module> ret1 = evaluation_model.eval(model, sess, rec_type='condition') File "MF/train_new_api.py", line 893, in eval res = pool.map(self.test_one_batch, self.generator_Rec_result_fast(model, sess, rec_type)) File "/home/xxx/anaconda3/envs/tf1.14/lib/python3.6/multiprocessing/pool.py", line 266, in map return self._map_async(func, iterable, mapstar, chunksize).get() File "/home/xxx/anaconda3/envs/tf1.14/lib/python3.6/multiprocessing/pool.py", line 376, in _map_async iterable = list(iterable) File "MF/train_new_api.py", line 934, in generator_Rec_result_fast sparse_cliked_matrix=sparse_cliked_matrix, user_pop=user_pop) File "MF/train_new_api.py", line 721, in do_recommendation topk_items = sess.run(self.condition_topk_idx, feed_dict={self.sparse_cliked_matrix: sparse_cliked_matrix}) File "/home/xxx/anaconda3/envs/tf1.14/lib/python3.6/site-packages/tensorflow/python/client/session.py", line 950, in run run_metadata_ptr) File "/home/xxx/anaconda3/envs/tf1.14/lib/python3.6/site-packages/tensorflow/python/client/session.py", line 1158, in _run self._graph, fetches, feed_dict_tensor, feed_handles=feed_handles) File "/home/xxx/anaconda3/envs/tf1.14/lib/python3.6/site-packages/tensorflow/python/client/session.py", line 474, in __init__ self._fetch_mapper = _FetchMapper.for_fetch(fetches) File "/home/xxx/anaconda3/envs/tf1.14/lib/python3.6/site-packages/tensorflow/python/client/session.py", line 261, in for_fetch type(fetch))) TypeError: Fetch argument None has invalid type <class 'NoneType'>
