St.file_uploader with TDMtermite (requires path of file)

[Specht]

Hi,

I try to read and process TDM and TDX files with python and streamlit.
The TDM file is a xml formated header file and the TDX file contains the measurement data as binary. Writing TDM and TDMS Files in LabVIEW - NI

For reading the files I use the package TDMterrmite. TDMtermite · PyPI

I upload the TDM and TDX files with st.fileuploader and try to pass them as input to the TDMtermite package but it seems that the TDMtermite package needs the path to a file and not a uploaded file.

This is the example code for TDMtermite:

import TDMtermite
import re

try :
jack = TDMtermite.tdmtermite(b’samples/SineData.tdm’,b’samples/SineData.tdx’)
except RuntimeError as e :
print("failed to load/decode TDM files: " + str(e))

I tried the following with streamlit:

files_tdm = st.file_uploader("TDM ", type=[“TDM”,“TDX”], accept_multiple_files=False)
files_tdx = st.file_uploader("TDX ", type=[“TDM”,“TDX”], accept_multiple_files=False)

try :
data_raw = TDMtermite.tdmtermite(files_tdm,files_tdx)
except RuntimeError as e :
print("failed to load/decode TDM files: " + str(e))

I get the error from TDMtermite: TypeError: expected bytes, NoneType found

Is it smehow possible to pass the “path to the cash” where the data is to a package?

Save the bytes to a NamedTemporaryFile as advised in this post:

Steamlit - Upload and use User Shapefile and Tif File

Hello @Geobro1! If you have a package like pyosp that requires an actual file path, one option is to use NamedTemporyFile, like this (this example uses PIL, but it should work with any library that is reading from a file) from tempfile import NamedTemporaryFile import streamlit as st from PIL import Image uploaded = st.file_uploader("Upload a file", type=["tif"]) if uploaded: with NamedTemporaryFile("wb", suffix=".tif") as f: f.write(uploaded.getvalue()) # f.name is the …

Hi Goyo,
