如何在加载图像后隐藏 streamlit 中的 file_uploader?
How does one hide the the file_uploader in streamlit after the image is loaded?
我正在使用 streamlit,我想做的是在一个有 2 列的容器中显示 2 个图像。
代码如下:
col1, col2 = st.columns(2)
with st.container():
with col1:
st.header('Top Glass Image')
top_image = st.file_uploader('Choose Bottom Glass Image', type='jpg', key=1)
if top_image is not None:
# st.write(top_image)
# st.write({'filename': top_image.name, 'file_type': top_image.type, 'filesize': top_image.size})
st.image(load_image(top_image), width=200)
with col2:
st.header('Bottom Glass Image')
bottom_image = st.file_uploader('Choose Bottom Glass Image', type='jpg', key=2)
if bottom_image is not None:
st.image(load_image(bottom_image), width=200)
屏幕如下所示:
理想情况下,我希望看到 2 个 file_uploader,一旦它们被选择并显示,只显示图像。
关于如何做到这一点有什么想法吗?
创建一个空容器作为支架。
参考:https://docs.streamlit.io/library/api-reference/layout/st.empty
with col2:
st.header('Bottom Glass Image')
holder = st.empty()
bottom_image = holder.file_uploader('Choose Bottom Glass Image', type='jpg', key=2)
# bottom_image = st.file_uploader('Choose Bottom Glass Image', type='jpg', key=2)
if bottom_image is not None:
st.image(load_image(bottom_image), width=200)
holder.empty()
