2. Context length is increased quickly due to the output of the package installation. So, changed the output of pip installs to a single line. https://github.com/OpenDevin/OpenDevin/issues/1616#issuecomment-2106134659

3. Changed regex to non-greedy versions for the following LLM output

Install the module using
<execute_ipython>
%pip install matplotlib
</execute_ipython>

Then import using this ...
<execute_ipython>
import matplotlib.pyplot as plt
</execute_ipython>

4. Refactored execute_cli
