I try a code like this:
import pandas as pd
import numpy as np
test_data='train.csv'
csv_reader = pd.read_csv(test_data)
x_list = csv_reader[['spectra']]
x_list = np.array(x_list)
x = [float(o) for o in x_list[0]]
y_list = csv_reader[['molecule']]
and then I get this:
Traceback (most recent call last):
File "D:/Users/11825/source/repos/deep/shiyishi.py", line 16, in <module>
x = [float(o) for o in x_list[0]]
File "D:/Users/11825/source/repos/deep/shiyishi.py", line 16, in <listcomp>
x = [float(o) for o in x_list[0]]
ValueError: could not convert string to float: '[0.0267469, 0.0272395,
0.0268747, 0.0267555]'
this is the data's picture:

The lists stored in column spectra are actually stored as string after you save and load the dataframe.
Try this right after you do read_csv:
import ast
csv_reader['spectra'].apply(ast.literal_eval)
csv_reader['molecule'].apply(ast.literal_eval)
