如何使用st.file_uploader在Streamlit中返回的内容?

我正在重用一些旧代码,但我试图通过使用Streamlit使其看起来更好。我正在添加一个file_uploader,我想用它上传CSV文件。

在此之后,我想读取该文件的前11行,以确定如何处理它(我的文件不一定都是相同的)。

但是,使用Streamlit,file_uploader返回一个类似字节的文件,因此我不能使用“I.readline()”,也不能使用我查看文件开头的代码的下一部分。

有人能帮我吗?

谢谢!

    ifile = st.file_uploader("Upload your CSV file here!", type="CSV",accept_multiple_files=False)
    if ifile is not None:
        with open(ifile, 'rb') as i:
            ln = 0header = []
            while ln < 11:
                header.append(i.readline())
                ln += 1
            if any("CGTR" in s for s in header):
                T = 1.e-3
            else:
                T = 200.e-6
            if header[0].startswith("#Version:"):
                data = np.genfromtxt(ifile, delimiter=",", skip_header=6, skip_footer=1, names=True) # Skip 6 first lines with header.
            elif header[0].startswith("#discard="):
                data = np.genfromtxt(ifile, delimiter=",", skip_header=1, skip_footer=1, names=True)

            else:
                skip = int(input("\nUnknown log format. How many header lines to cut before the channel names? "))
                data = np.genfromtxt(ifile, delimiter=",", skip_header=skip, skip_footer=1, names=True)
