 with 32bit python, pip install tensorflow return error message like  "ERROR: Could not find a version that satisfies the requirement tensorflow (from versions: none)" Googled it and one post of Stackoverflow.com says that it comes from 32bit version confliction issue.  So, I uninstalled it and reinstall python 64bit again. 

 Some of you may know, original ear pads of Sennheiser HD 238i left black leather flakes on ears.  But, it's replacement part is only leather ear pads.  I have googled "velvet earpads Sennheiser HD 238i" but nothing came up.  So, I googled "velvet earpads Sennheiser headphone" and something shown.  But it is for Sennhiser momentum on-ear headphones not HD 238i.  I purchased a pair of them for trial.  It comes and found that its size fits perfectly. but I need plastic parts for fitting with HD238i.  So, I detach it from original old earpads and glue it to new earpads.  Now, it works perfectly.  Sennheiser Momentum OnEar earpads @ USD3.50 https://ko.aliexpress.com/item/4001243791588.html
