3 years ago The mo_tf.py loader <class 'extensions.load.tf.loader.TFLoader'> extracts the node metadata.alphabet and its attributes using an ascii decoder. 0cx3 is the first half of utf-8 hex code in some UTF-8 characters. Hence the Error. The function responsible for extracting attributes is that is "extract_node_attrs" found in mo.front.extractor, where we find the error: 'Unexpected exception happened during extracting attributes for node {}.' , which looks familiar.
Running the command with --log_level=DEBUG:

Detailed description
I tried to convert a german language deepspeech tensorflow model and got the following error:
[ ERROR ] Exception occurred during running replacer "REPLACEMENT_ID" (<class 'extensions.load.tf.loader.TFLoader'>): Unexpected exception happened during extracting attributes for node metadata_alphabet. Original exception message: 'ascii' codec can't decode byte 0xc3 in position 6: ordinal not in range(128)
Steps to reproduce
tensorflow model optimizer with the following parameters:
./mo_tf.py --input_model=./models/output_graph.pb --input="input_node,previous_state_h,previous_state_c/read" --input_shape=[1,16,19,26],[1,2048],[1,2048] --output=logits,cudnn_lstm/rnn/multi_rnn_cell/cell_0/cudnn_compatible_lstm_cell/GatherNd,cudnn_lstm/rnn/multi_rnn_cell/cell_0/cudnn_compatible_lstm_cell/GatherNd_1 --freeze_placeholder_with_value="input_lengths->[16]" --disable_nhwc_to_nchw
The Problems are probably due to the german Umlaute, i.e. ö, ü, ä, ect. What do I do now?
