Deep Learning

How to make really empty tensor?

a = nn.Torch([])
b = torch.empty(2,3)
for i in rang(3):a = torch.cat(a, b, dim=0)

Mismatched attribute type in ’ : value’ ==> Context: Bad node spec for node. Name: OpType: Constant

pip uninstall onnx; pip install onnx==1.11

参考:
onnx
Try running yolov3_onnx sample

Can’t pickle local object 'MiniImagenet.init..

windows不支持：
No, it is not supported on Windows. The reason is that multiprocessing lib doesn’t have it implemented on Windows. There are some alternatives like dill that can pickle more objects.
类似问题：

Can’t pickle local object ‘DataLoader.__init__.<locals>.<lambda>'

Python 3.11 + pytorch in win11 has error

Use python 3.10.

Freeze layer bugs

Model.named_parameters()会忽略掉一些参数，比如：

Conv1.Bn.running_mean
Conv1.Bn.running_var 
Conv1.Bn.num_batches_tracked

解决方法，用model.state_dict()：

for k, v in model.state_dict().items():print kprint type(v)

参考资料：
Model.named_parameters() will lose some layer modules

Python

Import “imgaug.augmenters” could not be resolved PylancereportMissingImports

解决方法：

conda install imgaug

Cannot import name ‘_registerMatType’ from ‘cv2.cv2’ #1494

在cmd等命令窗口卸载imagua。Uninstall imagua in user folder by cmd.

pip uninstall imagua

The frame append method is deprecated use pandas.concat instead

从

self.F1ScoreDF = self.F1ScoreDF.append(pd.DataFrame(TCnn.F1Score).T)

改成

self.F1ScoreDF = pd.concat([self.F1ScoreDF, pd.DataFrame(TCnn.F1Score).T])

set_yticks does not show up

Map类型的数据不要用来做label。It is nothing about figure size, but just the label names are stored by map object, which is illegal.

ax.set_yticks(np.arange(data.shape[0]), labels=ClassNames)ClassNames = map(str.upper, opt.class_names)
to
ClassNames = list(map(str.upper, opt.class_names))

Anaconda

OMP: Error #15: Initializing libiomp5md.dll, but found libiomp5md.dll already initialized.

OMP: Hint This means that multiple copies of the OpenMP runtime have been linked into the program. That is dangerous, since it can degrade performance or cause 
incorrect results. The best thing to do is to ensure that only a single OpenMP runtime is linked into the process, e.g. by avoiding static linking of the OpenMP runtime in any library. As an unsafe, unsupported, undocumented workaround you can set the environment variable KMP_DUPLICATE_LIB_OK=TRUE to allow the program 
to continue to execute, but that may cause crashes or silently produce incorrect results. For more information, please see http://www.intel.com/software/products/support/.

解决方法：
将mkl在anaconda得navigator删除。
remove mkl in anaconda navigator。
