Thank you for your post. We noticed you have not filled out the following field in the issue template. Could you update them if they are relevant in your case, or leave them as N/A? Thanks. |
|
Thanks. I solved this problem |
|
I am also facing the same issue. Could you help me out to resolve this. |
|
Please check your command carefully. In my case, i wrote "pipelie" where alphabet "n" was missing. After correcting this, my problem was solved. |
|
Thanks for the quick reply.
However with model_main.py it has become really difficult to train a model
on custom dataset. I am not getting any detection after evaluation. My
model is not getting trained at all. I don't know where I m making
mistakes. Just curious whether you got success..? If yes then plz guide me
too.

My model is still on training. I’m using CPU training. |
|
Okay...how about your losses...? How you set the value of num_train_steps
and num_eval_steps?
My evaluation is showing average precision and recall as -1.00 which is
wrong. Don't know where I am making mistakes. How you passed the
arguments..?

I had the same problem with the the following command I changed it to the following I just removed the '' between the arguments and on the same line not multiline. The first command gave that error "TypeError: Expected binary or unicode string, got None" |
|
The same error |
|
@hammadullah125 HI! I want to know how did you deploy the model_main.py? I've set the model_dir,pipeline_config_path and the num_train_steps. and still get the error TypeError: Expected binary or unicode string, got None. here is my set of the code(in object_detection/model_main.py): and here is my error: |
Hey, I am getting the same error. Did you give path to any directory in that command ? |
|
Hey! im getting the same error. Any solution??? |
|
@stevelb's solution worked for me. I noticed that model_main.py loads up parameters on line 64 and following for an estimator. On changing the order of the parameters, the gripe "TypeError: Expected binary or unicode string, got None" is always on the last parameter. Look for "sys.exit(main(argv))" in the traceback. |
Hi, Any solution for this error? |
|
@SteveIb please can you explain more of your solution, am also facing the same problem Traceback (most recent call last): any solution |
|
@ALL I train the ssd_inception_v2_coco_2018_01_28, faster_rcnn_inception_v2_coco_2018_01_28, ssd_mobilenet_v2_coco_2018_03_29. However when I try to train on both the faster_rcnn_nas_coco_2018_01_28 and faster_rcnn_resnet50_coco_2018_01_28 I get the following error python model_main.py -- logtostderr -- train_dir=training/ --pipeline_config_path=training/faster_rcnn_nas_coco.config aceback (most recent call last): please any solution |
I fixed the error by giving the absolute directory path where ever it required. python model_main.py -- logtostderr -- train_dir=give the full path/training/ --pipeline_config_path=give the full path/training/faster_rcnn_nas_coco.config |
|
@drecryptos thanks for your response. I restarted my computed and it works. |
|
you can try something like this |
|
Got same issue with tf.lite.TocoConverter |
|
I have just encountered this error myself. This is likely nothing more than a syntax issue - check, check and doublecheck your commands and paths |
|
It's absolutely just a typo or syntax issue in your command. My mistake was that I wrote |
I:BERT_VEC:[graph:opt: 46]:model config: C:/Users/11360/PycharmProjects/test_albert/albert_base/albert_config.json
|
|
What to do？ |
|
hello so here I try to train a model of mask r cnn on my own give with the command but i get the following error could someone guided me please |
|
Got this error when converting a model to tf lite, this is the first result when googling the error.
I was passing in the model instead of the directory in which the model is saved. Hope this helps someone else |
Whenever I want to train the model with "model_main.py"
python3 model_main.py --logtostderr --train_dir=training/ --pipelie_config_path=training/ssd_mobilenet_v1_pets.configit's throwing this error.

Any guesses what is wrong?
