TypeError on the Only Tension Test Example 1

[subedinaresh]

I am trying to run the "VC_Tensile-Only_Calibration_Example_1" notebook in my Windows 10 PC using Jupyter Notebook in Anaconda 3 environment. When I ran the second cell in the given example (without any change) the program gives TypeError after fist iteration (exact error message below).

Do I need anything additional except Python and RESSPyLab to run the program?

Thank you.

C:\Anaconda3\lib\site-packages\RESSPyLab\scipy_dumper.py in dump(self, x, state)
32 np.savetxt(fi, x.reshape((1, len(x))), fmt='%7.6e')
33 with open(self.function_file, 'ab') as fi:
---> 34 fi.write('{0}, {1:5.4e}, {2:5.4e}\n'.format(it_num, f_val, norm_grad_lag))

TypeError: a bytes-like object is required, not 'str'

Can you try in Python2?

It worked in Python2, thank you.

Good to know. You can keep this issue open if you like since I (we) would like to have Python3 compatibility at some point. It's been a few years since I looked into the issue, but from what I remember the main issue was algopy, this may have been fixed since.

Sure, I am keeping this issue open because it would be nice to have Python3 compatibility in the future.
