Conv implementation does not support grouped convolutions for now. GPU / CPU

Hi, I am trying to train locally on my Mac without a GPU. Thank you Experiencor, I can train successfully on the raccoon dataset.

This is my config.json file:

`{ “model” : { “min_input_size”: 1000, “max_input_size”: 1920, “anchors”: [21,68, 27,83, 63,64, 77,77, 96,87, 111,101, 161,98, 178,131, 209,110], “labels”: [“1”, “2”, “3”, “4”] },

"train": {
    "train_image_folder":   "/Users/moritz.b/Desktop/keras-yolo3-master/yolo/",
    "train_annot_folder":   "/Users/moritz.b/Desktop/keras-yolo3-master/yolo/outputs/",
    "cache_name":           "localizer.pkl",
    "train_times":          6,
    "batch_size":           2,
    "learning_rate":        1e-4,
    "nb_epochs":            10,
    "warmup_epochs":        2,
    "ignore_thresh":        0.5,
    "gpus":                 "0",

    "grid_scales":          [1,1,1],
    "obj_scale":            5,
    "noobj_scale":          1,
    "xywh_scale":           1,
    "class_scale":          1,

    "tensorboard_dir":      "logs",
    "saved_weights_name":   "localisations.h5",
    "debug":                true
},

"valid": {
    "valid_image_folder":   "",
    "valid_annot_folder":   "",
    "cache_name":           "",
    "valid_times":          1
}

}`

When I start training, the error message says:

Traceback (most recent call last): File "train.py", line 290, in <module> _main_(args) File "train.py", line 267, in _main_ max_queue_size = 8 File "/Users/moritz.b/opt/anaconda3/envs/yolo3/lib/python3.5/site-packages/keras/legacy/interfaces.py", line 91, in wrapper return func(*args, **kwargs) File "/Users/moritz.b/opt/anaconda3/envs/yolo3/lib/python3.5/site-packages/keras/engine/training.py", line 1732, in fit_generator initial_epoch=initial_epoch) File "/Users/moritz.b/opt/anaconda3/envs/yolo3/lib/python3.5/site-packages/keras/engine/training_generator.py", line 220, in fit_generator reset_metrics=False) File "/Users/moritz.b/opt/anaconda3/envs/yolo3/lib/python3.5/site-packages/keras/engine/training.py", line 1514, in train_on_batch outputs = self.train_function(ins) File "/Users/moritz.b/opt/anaconda3/envs/yolo3/lib/python3.5/site-packages/tensorflow_core/python/keras/backend.py", line 3476, in __call__ run_metadata=self.run_metadata) File "/Users/moritz.b/opt/anaconda3/envs/yolo3/lib/python3.5/site-packages/tensorflow_core/python/client/session.py", line 1472, in __call__ run_metadata_ptr) tensorflow.python.framework.errors_impl.UnimplementedError: Fused conv implementation does not support grouped convolutions for now. [[{{node conv_81/BiasAdd}}]]

Does anybody have an idea?

@YoonSungLee: Yes. I was able to solve the problem. I had to use a different cache_name for the data in config.json. This error occurs because you have updated the output layer to accommodate new classes, but the pickle file created uses old class list.

Hope that helps.

@YoonSungLee Do you have backend.h5 in the same location of config.json? It is pretrained weights for the model.

Wow, by changing the h5 file, I’m able to get over the error. But I have another error, again. I’m very exhausted. Could you help me? The error is as following:
