遇到InvalidArgumentError

[qxyjyj]

您好，在运行代码main.py时，出现如下错误：
InvalidArgumentError (see above for traceback): You must feed a value for placeholder tensor 'Placeholder' with dtype float
[[Node: Placeholder = Placeholderdtype=DT_FLOAT, shape=[], _device="/job:localhost/replica:0/task:0/cpu:0"]]
不知道作者有没有遇见过这个问题？

can u please tell me where to feed placeholder....
data_prepare?
or in model?
And How...means give a example of placeholder

[qxyjyj]

When I run main.py to train model, there's a problem. The problem is:
File "F:\Anaconda3\envs\tensorflow\lib\site-packages\tensorflow\python\client\session.py", line 1052, in _do_call raise type(e)(node_def, op, message)
InvalidArgumentError: You must feed a value for placeholder tensor 'Placeholder' with dtype float [[Node: Placeholder = Placeholderdtype=DT_FLOAT, shape=[],_device="/job:localhost/replica:0/task:0/cpu:0"]]

So I step through each line of code. After running the code (_,summary = sess.run([train_step, merged],feed_dict =feed_dict, in line 123）, the program is out of the current function(inference(self,npy_path,test_path,model_index,train_flag=True)). The following code （train_writer.add_summary(summary, i) and saver.save(sess, './ckpt/archi-1', global_step=i + 1)）have not been executed. I can't solve this problem. Could you help me?

@qxyjyj @Muneeb121 Sorry ,i lost my dataset, i'll update the project later. 我现在手里没数据了，这个数据集不好下，过段时间再更新下。

@qxyjyj 您好！我运行main.py文件时，遇到了和您一样问题，不知道您的问题解决了没有，想请教您一下

不好意思，我也没有解决~ 在2018年12月8日 12:01，wangyage09<[email protected]> 写道： @qxyjyj 您好！我运行main.py文件时，遇到了和您一样问题，不知道您的问题解决了没有，想请教您一下 — You are receiving this because you were mentioned. Reply to this email directly, view it on GitHub, or mute the thread.

您好，为什么第一个尺寸的模型可以跑通，其他两个尺寸的模型跑不通呀？错误如下：“InvalidArgumentError (see above for traceback): logits and labels must be broadcastable: logits_size=[128,2] labels_size=[32,2]
[[node softmax_cross_entropy_with_logits_sg (defined at H:/自己的软件/代码文献/1/luna16_multi_size_3dcnn-master/new_model.py:267)。” 万分感谢，谢谢。
