I installed Streamlit version 0.68.0 in Anaconda navigator virtual environment on Windows. I am getting the following error with “streamlit hello”.
Bad message format
.concat(…).flatMap is not a function
I also tried versions 0.68.1 and 0.69.1, but that did not solve the issue
“steamlit hello” runs with vesion 0.64.0 with the same setup
go to terminal of anaconda’s virtual environment in which you had installed streamlit.
now write “pip install streamlit==0.65.0”
press enter
now write “streamlit hello”
It worked for me, I hope it should work for you also
being precise, streamlit 0.65.0 is more stable than latest version
In general, recommending people downgrade several versions is not good advice. If a version is released with a bug, we try to make patch releases as quickly as possible. But this requires users actually inform of us of bugs.
@Sanat, how did you install Streamlit, globally or are you running using a virtual environment? This sort of issue sounds like there is a dependency mismatch of some sort, which might be resolved by using a virtual environment/clean install.
Thanks Randy
I am using a virtual environment under Anaconda. It was a fresh virtual environment created specifically for the project I am working on. Here is the requirements list. Do you suspect any of these in particular?
kaleido==0.0.3
lmfit==1.0.1
numpy==1.19.1
openpyxl==3.0.4
pandas==1.1.0
plotly==4.9.0
scipy==1.5.2
streamlit==0.68.0
sympy==1.6.1
XlsxWriter==1.3.3
Thanks Baba.
I am actually planning to use the multi file upload functionality in the latest version. I guess it wasn’t there in 0.65.0. So that is not an option for me
Thanks @Sanat. I installed 0.68.0 in a fresh Miniconda environment with Python 3.8 and didn’t run into an issue. But, other users are reporting this issue as well.
Not exactly sure what to tell you here, as it seems like you’ve done all the normal debugging/installation steps
