Configs not persisting

[mpetruc]

Hi,
TradingAgend-gui was installed and started with uv:

git clone https://github.com/TheLocalLab/TradingAgents-GUI
cd TradingAgents-GUI
uv venv --python 3.12
uv pip install -e .
uv run python -m gui.app

Upon starting, an empty .env file is created in the TradingAgents-GUI folder.
In the Configuration section of the GUI, a custom Ollama Server URL is configured and 2 Custom Model Strings added. Click "Save Configuration" ->
"Configuration saved — will be loaded on next restart".
However:

• the configuration does NOT get saved. The .enf file is not updated, still empty (0Kb).
• When the page is reloaded, or the gui.app restarted, the custom config is gone, - the default Ollama url is shown.

I modified the .env.example file and created the .env file manually. Saved it everywhere i could thing of: TradingAgents-GUI, TradingAgents-GUI\gui, TradingAgents-GUI\cli, %USERPROFILE%.tradingagents, still nothing, the custom config does not get loaded. Here's my .env:

OLLAMA_BASE_URL=http://192.168.3.146:8080/v1

# Optional: override DEFAULT_CONFIG without editing code.
# Any TRADINGAGENTS_* variable below, when set, replaces the matching key
# in tradingagents/default_config.py. Values are coerced to the type of
# the existing default (bool / int / str), so "true"/"3" work as expected.
TRADINGAGENTS_LLM_PROVIDER=openai
TRADINGAGENTS_DEEP_THINK_LLM=gemma-4-31B-it-NVFP4-c131k-p8-vllm:thinking
TRADINGAGENTS_QUICK_THINK_LLM=gemma-4-31B-it-NVFP4-c131k-p8-vllm:thinking
TRADINGAGENTS_LLM_BACKEND_URL=http://192.168.3.146/8080/v1
#TRADINGAGENTS_OUTPUT_LANGUAGE=English
#TRADINGAGENTS_MAX_DEBATE_ROUNDS=1
#TRADINGAGENTS_MAX_RISK_ROUNDS=1
TRADINGAGENTS_CHECKPOINT_ENABLED=false

I can keep entering the info manually every time i start the app. However it would be nice not having to do so and just load it for the .env. Thank you!

Hey, why exactly did you use an alternate installation method? The project is specifically designed to use the install.bat or .sh if your on linux, which has additional scripts needed to ensure everything installs as it should.

I'm use uv exclusively for python env and package management. I have no system wide python installed.

Anyway: it seems that the ui DOES save the Ollama URL, but to %USERPROFILE%/.tradingagents/ui_state.json only (not to .env), while the API keys are saved to .env. The API keys saved to .env persist between restarts, so at least this part works. The problem is with the settings saved from the Configuration page. Also, adding OLLAMA_BASE_URL value manually to .env doesn't help as it is not read by the app upon restart, and the 'custom_backend_url' address in ui_state.json gets reset as soon as the Configuration page is accessed again after restart. Other than this small inconvenience, the app works marvelously, and i'm very grateful you chose to share your work with us!
