TypeError When Compiling Mobilenet V1 in Tensorflow

Hi,

I am working on deploying a modified version of Openpose library (pose estimation) from Github

https://github.com/ildoonet/tf-pose-estimation

The author migrated the original pose estimation from Caffe into Tensorflow, and export his model. I am compiling the .pd model under "./models/graph/mobilenet_thin/graph_opt.pb"

https://github.com/ildoonet/tf-pose-estimation/tree/master/models/graph/mobilenet_thin

but got a Type-error like below. (with virtualbox and Ubuntu 16.04, NCSDK v1)

…

tcwei@tcwei-VirtualBox:~/workspace/tfpose_test/models/graph/mobilenet_thin$ mvNCCompile graph_opt.pb -s 12 -in image -on Openpose/concat_stage7 -o graph_opt.graph

…

I checked some other discussions. It seems that most of time, the TypeError comes up with a unsupported issue and NCSDK doesn't support SSD-mobilenet. However, I am not sure if the model is using mobilenet v1 or SSD-mobilenet.

Also, through Tensorboard visualization as below:

I found that the model file includes mobilenet-V1 namescope and Openpose namescope. Would the other libraries/architectures like Openpose in my situation result in compiling failed? How to solve the problem?

Thanks.

I tried some simple architectures with my own layers and compiled them successfully. Hence, I am sure NCSDK supports customized architectures if they are successfully parsed. Just don't know which part of this tf-openpose library could result in compilation failed. Could anyone give us a suggestion?

Thanks.

Hi,

I found that "if statements" in the file of /usr/local/bin/ncsdk/Controllers/TensorFlowParser.py

For example:

"if shape.dims is None"

"if input_shape.dims is None"

For my graph input: (?, ?, ?, 3),

[Dimension(None), Dimension(None), Dimension(None), Dimension(3)]

Although element [0][1][2] are all None, the statements always return False and skip the value assigning inside the statement.

Therefore, the problem happens when it calls to acquire the value and find None_type.

Also, I am not sure if these can help me resolve the whole issue.

Could anyone help me for that?
