为什么我的deepbrain.extractor出现此错误？

Question

使用的代码是这样：

Step 16/17 : COPY /build/libs/myApp-0.0.1-SNAPSHOT.jar ./app.jar
COPY failed: stat /var/lib/docker/tmp/docker-builder441781405/build/libs/myApp-0.0.1-SNAPSHOT.jar: no such file or directory

当我运行它时，错误提示deepbrain.extractor没有模块运行。可以直接https://pypi.org/project/deepbrain/

获得此代码

然后，获得的错误是：

# Load a nifti as 3d numpy image [H, W, D]
img = nib.load(img_path).get_fdata()

ext=Extractor()

# `prob` will be a 3d numpy image containing probability 
# of being brain tissue for each of the voxels in `img`
prob = ext.run(img)
