cannot resume model for training

[TonightGo]

Hi, gleefeng, I got the following error when I ran the command "python3 compress_classifier.py --arch simplenet_cifar ../../../data.cifar10 -p 30 -j=1 --lr=0.01":

Do you have this issue?

[gleefeng]

You can git clone this project to solve this problem. some git messages must be checked by execution_env.py

Hi @gleefeng ,

Unfortunately resuming from a quantization session is not supported currently. See #21 (comment).

Cheers,
Neta

Yeah, it's ok, thank you!

I encountered the same problem:dog: I just want to evaluate the accuracy of quantized model.
Temporary modification:
quantizer.py:87

        # if train_with_fp_copy and optimizer is None:
        #     raise ValueError('optimizer cannot be None when train_with_fp_copy is True')

class WRPNQuantizer(Quantizer):

    def __init__(self, model, optimizer=None, bits_activations=32, bits_weights=32, bits_overrides=OrderedDict(),
                 quantize_bias=False):

@hustzxd the workaround you detail indeed works, thanks for posting here.
We'll work on a more permanent solution.

[stvreumi]

Hmmm...I also have problem here.
The quantized checkpoint can't be loaded for summary and testing, and the error message is the same.

[guyjacob]

We'll track this on #185, closing this one.
