Name of the layer cannot work

[jamestang0219]

Hello, i want to know whether this is my fault:

in your documents, you suppose us to define the name of layer when yield just like this:
yield { "pixel": pixels_float, 'label': int(label) }

and i follow your recommendation to yield like this:
yield {"fea_list":fea_list,"label":label}

then define the data_layer:
data = data_layer(name="fea_list", size=40)

but when i start to train the model, there are some errors:
I0926 14:43:32.013584 28460 Util.cpp:113] Calling runInitFunctions I0926 14:43:32.014166 28460 Util.cpp:126] Call runInitFunctions done.

i try to solve this problem, and i found if i delete the define of layer in yield code, it can successfully train the model:
yield fea_list,label

is this my fault or the architecture's fault?

if this is my fault, how can i solve this problem if i want fo define the name of layer in yield.

Is your code latest? This feature is supported by code after version 90b9cba. And currently there is no install package for this, you should compile it from source.

[jamestang0219]

PaddlePaddle 0.8.0b, compiled with
with_avx: ON
with_gpu: ON
with_double: OFF
with_python: ON
with_rdma: OFF
with_glog: ON
with_gflags: ON
with_metric_learning:
with_timer: OFF
with_predict_sdk:

i use the latest source to compile.

@jamestang0219 But the latest PaddlePaddle is 0.8.0b1, see here.

You may uninstall the PaddlePaddle before. Just run

pip uninstall paddle pip uninstall py_paddle

and remove the directory /usr/local/opt/paddle, script /usr/local/bin/paddle

@reyoung you mean i need to change the code like this and recompile the project?
set(PADDLE_PATCH_VERSION 90b9cba)

[reyoung]

@jamestang0219 Change the code is not needed. But in the latest code, PaddlePaddle is 0.8.0b1, not 0.8.0.b0 which is shown by paddle version in your comment.

So maybe your PaddlePaddle is not the latest version.
