from tensorflow to mxnet

[JackieLee2011]

Hi @kitstar , I want to convert tensorlflow to mxnet. however, I encounter a bug when I run the following script:
python -m mmdnn.conversion._script.IRToCode -f mxnet -d converted_mxnet.py -n converted.pb -w converted.npy

Before that, I get 'imagenet_inception_v3.json', 'imagenet_inception_v3.h5', 'converted.json', 'converted.pb' and 'converted.npy' successfully as the example (from tensorflow to CNTK) provided in the README.

The bug is:
Parse file [converted.pb] with binary format successfully. Detect input layer [input_1] using infer batch size, set it as default value [1] Traceback (most recent call last): File "/usr/lib64/python2.7/runpy.py", line 162, in _run_module_as_main "__main__", fname, loader, pkg_name) File "/usr/lib64/python2.7/runpy.py", line 72, in _run_code exec code in run_globals File "/media/disk1/xxx/code/projects/tensorflow-models/MMdnn/mmdnn/conversion/_script/IRToCode.py", line 120, in <module> _main() File "/media/disk1/xxx/code/projects/tensorflow-models/MMdnn/mmdnn/conversion/_script/IRToCode.py", line 115, in _main ret = _convert(args) File "/media/disk1/xxx/code/projects/tensorflow-models/MMdnn/mmdnn/conversion/_script/IRToCode.py", line 56, in _convert emitter.run(args.dstModelPath, args.dstWeightPath, args.phase) File "mmdnn/conversion/common/DataStructure/emitter.py", line 21, in run self.save_code(dstNetworkPath, phase) File "mmdnn/conversion/common/DataStructure/emitter.py", line 53, in save_code code = self.gen_code(phase) File "mmdnn/conversion/mxnet/mxnet_emitter.py", line 120, in gen_code dirname = os.path.dirname(self.output_weights_file) File "/home/xxx/softwares/tensorflow/lib64/python2.7/posixpath.py", line 129, in dirname i = p.rfind('/') + 1 AttributeError: 'NoneType' object has no attribute 'rfind'

What is the problem?

For mxnet emitter, you should set a output mxnet checkpoint name, such as
python -m mmdnn.conversion._script.IRToCode -f mxnet -dw mxnet_inception_v3-0000.params ...

Thanks.

@kitstar It works well, thanks.

Hi @kitstar , When I convert tensorlflow to mxnet, the following error occurs?

python -m mmdnn.conversion._script.IRToCode -f mxnet --IRModelPath resnet50.pb --dstModelPath mxnet_inception_v3.py --IRWeightPath resnet50.npy -dw mxnet_inception_v3-0000.params

The error is IsADirectoryError: [Errno 21] Is a directory: 'mxnet_inception_v3-0000.params'

[Cheng(Kit) CHEN]

Should be fixed in newest mmdnn.

啥原因啊

Hello, is it possible to convert a h5-stored tensorflow model to MXNet or does it have to be a ckpt file ?
Is it possible to get not only the model, but also the MXNet code ?
