Fix ValueError: invalid literal for int() with base 10: '' in tqdm/utils.py #10673
Description
Valid for conda version > 4.8.3
At line-336 in _vendors/tqdm/utils.py (db380cc#diff-a2e083f5ce1f74db5268f51073df0c2cdb07b7e2d64f65be3e65f5964e023417), os.environ is called which returns an empty string and thus fails with value error when int() is called on it. In the previous code, a default value of 1 was used (line-204 in _vendors/tqdm/_utils.py ). I suggest that the line-336 in _vendors/tqdm/utils.py should be changed to return [int(os.environ.get(i, 1)) - 1 for i in ("COLUMNS", "LINES")]
