I have the same question!Have you solved it?

[sivakumarch]

Facing the same issue when I tried to start the server, here is the stacktrace - looks like issue related to tensorflow 2.0 updates. Please let us know if this will be addressed soon.

sorry - downgrading to tensorflow 1.x worked, it was due to 2.0 updates. I tried to upgrade the bert_serving scripts using 2.0 tools, but I wasn't successful as there were some errors.

I have the same question!Have you solved it?

I change to another env with
tensorflow 1.13.1 bert-serving-client/server 1.9.9 python3.7 and it works well😀

but with my env with tensorflow 1.14.0 it seems doesn't work....

[ginward]

downgrading to tensorflow version 1.15 seems to work for me

[nonononanana]

check the path of the downloaded model.

thank you so much , finally it work for me !

[sprite0153]

I meet that issue to..but I don't want to downgrading,Is there have any other settlement work for 2.0

[harshitbh]

I am still facing the above issue have tried couple of solutions. Version - tensorflow-cpu = 1.13.1 Bert_serving_client = 1.9.9 Bert_serving_server = 1.9.9

[harshitbh]

I am running the below command after locating at model_dir command bert-serving-start -model_dir uncased_L-2_H-128_A-2\ -cpu files present in model_dir :bert_config.json,bert_model.ckpt.data-00000-of-00001,bert_model.ckpt.index,vocab.txt have tried with providing absolute path till model directory too system config - 12 gb ram. let me know how could I resolve this.Thanks in advance

I am getting the same problem in windows, although I tried all the methods. "TypeError: 'NoneType' object is not iterable". Please somebody help me.

你们模型目录写错啦

[Doracoco]

你们模型目录写错啦 那应该怎么写呢，没有发现哪里写错了

你试试绝对路径

有可能是tensorflow版本过高，api不兼容，只支持1.x.x版本的。报错信息跟进去，可以看到源码，大于1的版本会报一个未测试验证的警告。

你最后怎么弄的呀 我要崩溃了
