I am trying to run the LEAN report creator on a local Linux machine using the following command line instruction according to tutorial:
./QuantConnect.Report.exe --backtest-data-source-file sample.json --report-destination Example.html I have changed the permissions of the .exe to grant it execution priveleges, but am still receiving the following error: bash: ./QuantConnect.Report.exe: cannot execute binary file: Exec format error I believe this is because the architecture of the .exe is a 32 bit (i386) executable that cannot be executed in Linux. Is there any workaround to this for LEAN development on Linux?
Aaron Janeiro Stone
Have you tried ```mono QuantConnect.Report.exe --backtest-data-source-file sample.json --report-destination Example.html```
CAPOCAPITAL
Aaron - Thank you for the suggestion. I now see the report executable is attempting to parse files and I am now running into a possible path error. My terminal command produces the following output
$ sudo mono ./Lean/Report/bin/Debug/QuantConnect.Report.exe --backtest-data-source-file ./Lean/Results/BasicTemplateFrameworkAlgorithm.json --report-destination ./Lean/Results/Example.html

The path /Data/market-hours/market-hours-database.json looks fine and I did confirm the file is in the correct place.
Jasper van Merle
Hi CAPOCAPITAL, please try running the report creator from the ./Report/bin/Debug directory with mono QuantConnect.Report.exe --backtest-data-source-file ../../../Results/BasicTemplateFrameworkAlgorithm.json --report-destination ../../../Results/Example.html.
CAPOCAPITAL
Thank you Jasper - I am one step closer. After running the command from within the Debug directory I receive a System.DLL.Notfoundexception

The report creator requires Python to be set up within LEAN. See Algorithm.Python's readme.md file, it contains the following steps to fix that error:
- Find libpython3.6m.so in your Python installation folder. If you installed Python with Miniconda, it may be found at:
For the report creator you'll also need to install matplotlib using pip install matplotlib in the Python environment you set up in Python.Runtime.dll.config./home/{your_user_name}/miniconda3/envs/{qc_environment}/lib/libpython3.6m.soNote that you can create a new virtual environment with all required dependencies by executing:
Â
conda create -n qc_environment python=3.6.8 cython=0.29.11 pandas=0.25.3 wrapt=1.11.2Â
Open Lean/Common/Python/Python.Runtime.dll.config, add the following text under <configuration> ... </configuration> and save:
Â
<dllmap dll="python3.6m" target="{the path in step 1 including libpython3.6m.so}" os="linux"/>Â
