Pricing Asian Options' Cell Notebook References Code in a Separate Branch That Hasn't Been Merged into Develop

When troubleshooting an issue with a Jupyter notebook, it's essential to provide detailed system information to help identify the root cause of the problem. In this case, we're using a Linux system with the following specifications:

OS Platform and Distribution: Linux selle 6.8.0-48-generic #48~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Mon Oct 7 11:24:13 UTC
Are you using Google COLAB notebook: Yes
Browser if using Jupyter: Safari
Browser version if using Jupyter: 18.3 (20620.2.4.11.5)
Mobile device (e.g. iPhone 8, Pixel 2, Samsung Galaxy) if the issue happens on mobile device: N/A
QMCPy installed from (source or binary): source
QMCPy version: Develop branch
Python version: 3.9.13
Installed using virtualenv? pip? conda?: conda
GCC or Windows C Compiler version: gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0

The issue arises in cell five of the PricingAsianOptions Jupyter notebook. The code in this cell is attempting to create a LookBackOption object using the qp module, but it's encountering an AttributeError.

The error message is as follows:

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
Cell In[13], line 4
      1 #LookCall = qp.LookBackOption(qp.IIDStdUniform(dimension=d,seed=7), volatility= volatility,start_price= initPrice,
      2 #                             interest_rate = interest,t_final=1/4,call_put='call',in_out = 'in')
      3 #x = LookCall.discrete_distrib.gen_samples(sampleSize)
----> 4 LookCall = qp.LookBackOption(volatility= vol,start_price= initPrice,
      5                              interest_rate = interest,t_final=1/4,call_put='call')
      6 x = LookCall.discrete_distrib.gen_samples(2**12)
      7 y = LookCall.f(x)

AttributeError: module 'qmcpy' has no attribute 'LookBackOption'

To reproduce the issue, simply run the PricingAsianOptions.ipynb notebook and navigate to cell 13. The qp.LookBackOption function should raise an AttributeError.

The expected behavior is that the code in cell 13 should not raise an AttributeError, as the LookBackOption class is not available in the qp module. However, since the code is referencing a separate branch that hasn't been merged into the develop branch, this is the expected behavior.

Unfortunately, we cannot provide a screenshot of the issue, as it's a Jupyter notebook error. However, the error message above provides a clear indication of the problem.

The code for the LookBackOption class has not been merged due to issues with the code. This was discussed on Mon Mar 10 7:05. As a result, the qp module does not have the LookBackOption attribute, leading to the AttributeError.

To troubleshoot this issue, we can take the following steps:

Verify the code: Ensure that the code in cell 13 is correct and not referencing a non-existent attribute.
Check the qp module: Verify that the qp module has the LookBackOption class and that it's correctly imported.
Merge the separate branch: Merge the separate branch into the develop branch to ensure that the LookBackOption class is available in the qp module.
Update the Jupyter notebook: Update the Jupyter notebook to reference the correct branch and ensure that the code is working as expected.

By following these troubleshooting steps, we should be able to resolve the issue and ensure that the PricingAsianOptions Jupyter notebook is working correctly.
Pricing Asian Options' Cell Notebook References Code in a Separate Branch That Hasn't Been Merged into Develop: Q&A

A: The issue arises in cell five of the PricingAsianOptions Jupyter notebook, where the code is attempting to create a LookBackOption object using the qp module, but it's encountering an AttributeError.

A: The error message is as follows:

---------------------------------------------------------------------------

      6 x = LookCall.discrete_distrib.gen_samples(2**12)
      7 y = LookCall.f(x)

AttributeError: module 'qmcpy' has no attribute 'LookBackOption'

A: The expected behavior is that the code in cell 13 should not raise an AttributeError, as the LookBackOption class is not available in the qp module. However, since the code is referencing a separate branch that hasn't been merged into the develop branch, this is the expected behavior.

A: The cause of the issue is that the code for the LookBackOption class has not been merged due to issues with the code. This was discussed on Mon Mar 10 7:05. As a result, the qp module does not have the LookBackOption attribute, leading to the AttributeError.

A: To troubleshoot this issue, you can take the following steps:

Verify the code: Ensure that the code in cell 13 is correct and not referencing a non-existent attribute.
Check the qp module: Verify that the qp module has the LookBackOption class and that it's correctly imported.
Merge the separate branch: Merge the separate branch into the develop branch to ensure that the LookBackOption class is available in the qp module.
Update the Jupyter notebook: Update the Jupyter notebook to reference the correct branch and ensure that the code is working as expected.

A: The solution to this issue is to merge the separate branch into the develop branch to ensure that the LookBackOption class is available in the qp module. Additionally, update the Jupyter notebook to reference the correct branch and ensure that the code is working as expected.

A: To prevent this issue in the future, ensure that all code changes are properly merged into the develop branch before referencing them in the Jupyter notebook. Additionally, regularly update the Jupyter notebook to reference the correct branch and ensure that the code is working as expected.

By following these troubleshooting steps and solutions, you should be able to resolve the issue and ensure that the PricingAsianOptions Jupyter notebook is working correctly.
