Error while installing dependencies

I was trying to install the following requirements

While installing those dependencies in streamlit sharing the following error occured.

error: can't find Rust compiler
  If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it. Installing from the wheel would avoid the need for a Rust compiler.
  To update pip, run:
      pip install --upgrade pip
  and then retry package installation.
  If you did intend to build this package from source, try installing a Rust compiler from your system package manager and ensure it is on the PATH during installation. Alternatively, rustup (available at is the recommended way to download and update the Rust compiler toolchain.

Hi @sowmya_lr

Was this on your personal computer or on the streamlit-sharing server?
Obvious from the error Rust is not installed, and this is needed for compiling transformers==2.5.1. See issue on github.

On your personal computer you can download and install Rust from or try the proposed solution on github if you’re on mac/linux. I’m not sure if this is possible on the streamlit servers.

Issue is coming in streamlit sharing while installing dependencies.In my local computer I am able to work.

Then the streamlit sharing server does not support compiling packages using Rust.
You could try to compile a installation wheel locally for transformers==2.5.1, put it in you repo and refer to the local package in your requirements.txt file. I don’t know how well Rust compiles cross platform.

Perhaps the streamlit team can help with the Rust compiling on the server.

@sowmya_lr what’s your repo?

About rust compiler you can add a packages.txt file on your repo, with the debian package required for it, rustc, I guess.
