我在Bootstrap 4中的自定义文件输入类有问题.在我选择了要上传的文件后,文件名不显示.
我用这个代码:
<div class="input-group mb-3">
<div class="custom-file">
<input type="file" class="custom-file-input" id="inputGroupFile02">
<label class="custom-file-label" for="inputGroupFile02">Choose file</label>
</div>
<div class="input-group-append">
<button class="btn btn-primary">Upload</button>
</div>
</div>
知道如何解决它而不会太复杂吗？
I have to convert some files which come by default as .dcm to .png, I've found some code samples to achieve that around here but the end results are too bright. Could anybody have a look at this, please?
def convert_to_png(file):
ds = pydicom.dcmread(file)
shape = ds.pixel_array.shape
# Convert to float to avoid overflow or underflow losses.
image_2d = ds.pixel_array.astype(float)
# Rescaling grey scale between 0-255
image_2d_scaled = (np.maximum(image_2d,0) / image_2d.max()) * 255.0
# Convert to uint
image_2d_scaled = …我试图将我的应用程序分成两个 Docker 服务 - 前端和后端，我的项目布局看起来与此类似。
