Warning: Using ``*`` for matrix multiplication has been deprecated since CVXPY 1.1.

Hello, I am using Dipy for IVIM. I am using the command for the fit: ivimmodel_vp = IvimModel(gtab, fit_method='VarPro', bounds=([0., 0., 0.], [0.9, 0.9, 0.9])) However, when I run my script, I am continuing to have the warning: warnings.warn(__STAR_MATMUL_WARNING__, UserWarning) /Users/xxxxxxx/anaconda3/lib/python3.8/site-packages/cvxpy/expressions/expression.py:524: UserWarning: This use of ``*`` has resulted in matrix multiplication. Using ``*`` for matrix multiplication has been deprecated since CVXPY 1.1. Use ``*`` for matrix-scalar and vector-scalar multiplication. Use ``@`` for matrix-matrix and matrix-vector multiplication. Use ``multiply`` for elementwise multiplication. I would like to know if this warning can affect my results. Also, I tried to remove it by removing some lines in expression.py, and now, I do not have the warning. However, I am not sure if my procedure is correct. Thanks, Maurizio
