BUG合集

Python

File “/home/XXX/Code/…”, line 50, in init
self.input_shape = input_shape
File “/home/XXX/.local/lib/python3.7/site-packages/tensorflow/python/keras/engine/base_layer.py”, line 1639, in setattr
super(Layer, self).setattr(name, value)
AttributeError: can’t set attribute

• 解决方案
  被赋值的变量与super的属性重名了，且其不是一个setter，更改一下变量名，改为“self.inputShape = input_shape”就可以了。

Pycharm/Python OpenCV and CV2 install error
ERROR: Could not find a version that satisfies the requirement cv2 (from versions: none)
ERROR: No matching distribution found for cv2

• 解决方案
  You are getting those errors because opencv and cv2 are not the python package names.
  These are both included as part of the opencv-python package available to install from pip.

File “h5py/_objects.pyx”, line 55, in h5py._objects.with_phil.wrapper
File “h5py/h5f.pyx”, line 78, in h5py.h5f.open
OSError: Unable to open file (file signature not found)

• 解决方案
  源文件下载的时候有问题，在网页从download进再下载一次；检查上一次访问该文件时是否用close()正常关闭了

  通过命令 sudo du -h --max-depth=1，查看内存使用情况，清理一下内存

FutureWarning: The behavior of AMI will change in version 0.22. To match the behavior of ‘v_measure_score’, AMI will use average_method=‘arithmetic’ by default.

• 解决方案：使用
  from sklearn.metrics.cluster import adjusted_mutual_info_score adjusted_mutual_info_score(labels_true, labels_pred, average_method='arithmetic')

linux下-bash: ***: command not found

• 解决方案
  一般就是最近添加PATH路径的时候没有写对，一种直接的方法就是进入 /etc 文件夹，用文本编辑修改正确profile文件，可能会提示没有权限修改，复制到别的文件夹改好后再copy回来；或者参考下面的链接
